Welcome to the Into Indie Games walkthrough for Days 11 to 30 in Treasure Beach.
Treasure Beach is a cozy job simulator where you have to find items that are buried on the beach. You can either find trash, normal items, or some that can sell for a lot of money. We have already published the first 10-day walkthrough, which can help you get started with very little effort.
In this guide, we will provide you with a complete walkthrough of the next 20 days, covering Days 11 through 30 in Treasure Beach.
For more information, you can head over to its Steam page.
Disclaimer
Treasure Beach is an RNG-based game where the items you find depend heavily on luck, so you may not receive the same items on the beach that we found during this playthrough. However, after playing through the first 10 days multiple times, we have noticed that getting lucky for several days in a row is not unusual. That said, do not compare your items with the ones we received during our playthrough. Other than that, our walkthrough makes it much easier to understand everything you need to know during the first 10 days of the game.

Treasure Beach – Day 11 Walkthrough

After unlocking the Town Square by reaching Day 10, complete the day and start the next one. You may not have a lot of money by now, mainly because of all the different upgrades and items you have purchased. However, that is completely okay, as that situation will change soon enough.
Start Day 11 and use the Sonar Radar to check how many items are buried on the beach. Once you have done that, start combing through the beach using your rake. Do not stop until you have found every single item. If you think something can sell for a high price, make sure to trust your intuition and place it in your bag.
That said, items such as tropical wear that you find regularly and boarding pass tickets are simply not worth much. They are usually better off being recycled because at least you will earn a ticket and have a chance to get lucky. Once you are done collecting the items, head to the recycling center and recycle all of the trash.
Note
As you start Day 11, keep in mind that there is a mini-game on the island called Seashell Merge. In this game, you need to merge seashells together to create shells with higher values. Each day, you will receive a limited number of clicks that can be used on the board, and you should use them to merge as many seashells as possible. Every time you successfully merge seashells, you will earn coins. Additionally, once you obtain all of the hearts from the granny in the Town Square, you will receive more daily clicks, allowing you to make even greater progress in the mini-game.
Head To The Workshop

After you are done recycling, it is time to head to the workshop. We already had a lot of items stored away, so if the same is true for you, do not worry too much about the ones already sitting on the shelf. Simply add more items to the shelf, pick up the ones that have dried, and place them into your basket so that you can sell them.
Once you are done, it is time to head to the shop.
Head To The Shop
Sell your items and try not to bargain if you are already being offered a good price. For a rare card, we were offered 100 coins, but we decided to bargain anyway. After attempting to bargain only once, we lost the customer completely. So, it is generally better not to become too greedy.
Also, make sure to keep an eye on the crab, as clicking on it will reward you with 25 coins.
Note
Another thing worth noting is that the Town Square is an extremely important location. Each day, there can be a different pair of characters there. You should talk to them and make sure to remain respectful during your conversations in order to earn their favor. Upon reaching the maximum number of hearts with a character, you will unlock a permanent reward. Therefore, make sure to visit the Town Square every day and speak with whoever is there in a respectful manner.
Treasure Beach – Day 12 Walkthrough

Once you are done with Day 11, head to the beach. This time, if you have not already unlocked the Law Firm, it is time to do so. In order to unlock the Law Firm, you need to complete a few tasks. There is a good chance that you have already completed them by this point. However, if the beach is still polluted, then you should head there and hover your mouse over the objects that are causing the pollution.
Doing so will tell you exactly what needs to be done, and the required tasks are not difficult at all. Once you have completed those objectives and cleaned up the pollution, the Law Firm will be unlocked. Then, use the Sonar Radar to check how many items are buried and take everything you find with you.
After that, simply head to the recycling center, then go to the workshop, and finally sell your items. Once you are done, head to the Beach Fair and try your luck for some additional money.
Treasure Beach – Day 13 Walkthrough

Follow the usual routine, and once you are done collecting the valuable items, head to the recycling center and recycle the trash. The items you should focus the most on recycling are generally paper-related and plastic-related items. Electronics should, most of the time, be kept in your bag for restoration.
Once you are done recycling, head to the workshop and restore your items. If you find a rare bottle, then you should use the Glass Repairing Kit on it as well. If you have not unlocked it yet, you really should because it will come in handy quite often. Then you should sell your items and start the next day.
Treasure Beach – Day 14 & 15 Walkthrough

Start Day 14 and collect all the items from the beach. If you already have a large number of items sitting on the shelf and still have not sold everything, you should consider placing more of the lower-value items into the recycling bin. Doing so will help you organize your inventory much more efficiently.
However, if you find items such as a wedding ring, a laptop, or a rare card, you definitely do not want to overlook them. Once you are done collecting items, repeat the normal process and eventually sell your items. Now, before you start the next day, there is something you need to purchase.
Unlock Pump Kit

Once you are done for the day, head to the electronics store and purchase the Pump Kit. This unlocks the Inflation Station in the workshop, which will come in handy later on. The DIY store also has some excellent upgrades, but for now, do not focus too much on them. Purchasing those upgrades will be much more beneficial once you have enough money available.
After you are finished with that, start Day 15 and repeat this exact same procedure once again.
You may also have a ticket or two by this point, so head over to the Beach Fair and try your luck. By now, you should have saved a good amount of money, but that still is not going to be enough for the DIY store, as purchasing multiple upgrades there at once is generally the most efficient approach.
Treasure Beach – Day 16 & 17 Walkthrough

Now, once you have started Day 16, you should focus on one particular thing. First, check how many items are buried on the beach. Once that is done, you should click on the book located at the top-left side of the screen. It will be positioned just below your coin count. After clicking on it, you will see several categories such as Lost Love, Mystical Memories, Pirate Relics, Mysterious Bottles, Smuggler’s Stash, and more.
Many of the items found within these categories can sell for a significant amount of money, especially if they have a valuable theme associated with them, such as a wedding ring from the Lost Love category. Therefore, whenever you discover something new from a category that sounds rare, special, or valuable, you should probably hold onto that item instead of getting rid of it too quickly.
From what we have noticed, items from categories such as Library Treasures, Tidal Treasures, and Children’s Kit generally do not sell for very much. However, there are still bound to be certain items within these categories that can fetch a respectable price, so do not completely ignore them.
Once you have collected all the items from the beach, recycle the trash, restore any useful items, sell them, and then start Day 17. Repeat the same process throughout Day 17, and once you are done, you will be ready for the next day.
Treasure Beach – Day 18 Walkthrough

Once you have started Day 18, collect all the items from the beach and complete your usual tasks. Do everything you normally have to do, but do not start the next day immediately. Once you have recycled, restored, and sold your items, it is finally time to purchase your first permit.
Buy The Whistle Island Permit

Head to the Law Firm, and there you will notice the first permit available for purchase. It costs 250 coins and is the one that you should buy. Purchasing this permit will unlock the first island for you. The island is called Whistle Island and can be found on the right side of the map, slightly north.
Note: You should make it a habit to visit the Town Square every day and talk to whoever happens to be there. During your conversations with them, make sure to be respectful whenever possible, as doing so will reward you with +1 Heart.
Treasure Beach – Day 19 & 20 Walkthrough

Now, you need to start Day 19 on Whistle Island, the new island that you recently unlocked. The overall process here is going to remain the same, but keep in mind that you are going to find new items on this island. There will, of course, still be some familiar items as well, but you should pay close attention to any discoveries because they are likely to provide better profits.
This island will not contain the same shops that are available on your main island. You will need to return to the original island whenever you want to recycle, restore, or sell your items. Also, while searching for items on the beach, you may notice bubbles appearing on your screen from time to time.
Make sure to tap those bubbles whenever they appear because they will reward you with free coins. Once you are done collecting items, recycle them where necessary, restore the valuable ones, and sell everything you can. After that, start the next day. Repeat the exact same process on Day 20, and once you are done, it is finally time to purchase a few new upgrades.
Head To The Electronics Store
Now that you have a Jewelry Station where you can create different types of jewelry from the gemstones you find, you also need a better polishing device. Creating jewelry from gemstones already increases their value by a considerable amount, but having those gemstones polished to a higher standard will make them worth even more.
Therefore, head to the Electronics Store and purchase the Premium Polishing Machine. This upgrade will not unlock an entirely new device. Instead, it will significantly improve the polishing machine that you already own. The upgrade costs 450 coins, which should not be too difficult to afford by this point in the game.
Unlock The Battery Kit

You should still have enough money remaining to purchase the Battery Kit as well. This upgrade unlocks the Electronics Repair Station in your workshop, which is a major improvement because electronics already sell for a substantial amount of money. Being able to repair them properly will increase their value even further.
Purchase this upgrade as soon as possible. However, if you do not currently have enough money, head over to the Beach Fair and use any tickets that you have saved up. Then, use any money that you potentially win there to purchase the Battery Kit and unlock the new station.
Treasure Beach – Day 21 & 22 Walkthrough

After spending a lot of money on upgrades and unlocking several new items, you probably will not have much money left right now. However, that is completely alright because you now have an entirely new island to gather items from, and you will start finding some pretty valuable ones.
So, head over to Whistle Island and begin Day 21. Start your day by clearing everything from the beach and then use your Sonar Radar to see how many items are buried beneath the sand. Once you have done that, begin combing through the beach and do not stop until you have found every single item.
Also, make sure to click on the bubbles that randomly appear across the beach, as they contain free money. Once you have collected all of the items from the beach, it is time to head to the workshop.
Head To The Workshop

Inside the workshop, you will now have a new station available, and your polishing machine will be significantly better. Therefore, if you have any items that require the new station, make sure to use it. Other than that, any items that require polishing should now sell for even more because the game specifically describes the upgrade as a significant improvement.
Once you have restored your items, head to the recycling center and recycle all of the trash. Once you are done, head to the Town Square and speak with the people there. You should try to remain completely positive during these conversations in order to improve your popularity and reputation with them.
Now, if you have any tickets available, you can head to the Beach Fair and try your luck. Once you are done there, it is time to head to the shop and sell your items. Keep an eye out for the crab on either side of the screen while you are selling your items because clicking on the crab rewards you with 25 coins.
Once everything is done, it is time to start the next day.
Note: While it can be tempting to buy items from the DIY Store because they increase the base prices of your items, improve customer patience, and make negotiations easier, you should remain patient for now. This is because the Electronics Store contains items that help you restore your finds. As a result, even without negotiating, you will be able to earn a much better price for your items. Once you have unlocked most of those upgrades, then purchasing items from the DIY Store will make much more sense.
Starting Day 22

Once you have started Day 22 on Whistle Island, collect everything you can find on the beach. If you find Mysterious Bottles, then the safest option is to keep them in your bag rather than placing them into the recycling bin. The same generally applies to electronics and jewelry.
Collect everything from the beach and then head straight to the recycling center. Recycle your trash and then head over to the Town Square. After that, it is time to restore your items and then sell them. Once you have completed your usual daily routine, it is time to buy something new from the Electronics Store.
Buy The Rarity Meter

This is arguably one of the most useful and important upgrades in Treasure Beach. The Rarity Meter tells you the approximate value of an item that you find on the beach, which can be incredibly helpful. With this upgrade, you will no longer have to guess which items are worth keeping.
For example, you might find a book with a mysterious title and assume that it is worth a lot of money. However, that may not actually be the case. The Rarity Meter helps you identify whether an item is genuinely valuable or not. Once you have purchased it, you should still have enough money left to buy one or two additional upgrades.
Treasure Beach – Day 23 & 24 Walkthrough

After purchasing the Sewing Kit, start the next day on Whistle Island. Once you have done that, dig up the buried items, restore the valuable ones, recycle the trash, and then head back home. Your home can be found to the south and slightly to the left of the main island.
There, you will find a Quest Board that provides various objectives for you to complete over time. Each quest rewards you with 50 coins, and there is a good chance that you have already completed some of them without realizing it. For example, you are highly likely to have already completed the quest that requires you to sell 50 items.
That said, many of the other quests involve finding every item from a specific collection. As a result, those objectives can only be completed with time and continued exploration. Now, you need to buy one item from the electronics store.
Buy The Sewing Kit

So far, you may not have been getting a particularly good price for clothing items, and that is completely understandable. The main reason for this is that you do not yet have the Clothing Restoration Station unlocked in your workshop. Therefore, purchase the Sewing Kit from the Electronics Store, and you will unlock it.
The Sewing Kit costs 375 coins, which should not be a problem for you by Day 23 or 24.
Head To The Shop
After that, head to the shop and sell your items. Once you are done, use your tickets if you have any available and then start the next day. Repeat the exact same process on Day 24 and then move on to the following day.
Treasure Beach – Day 25 & 26 Walkthrough

Start the day and head over to Whistle Island. Continue finding items, and if you discover the Secret Stash from the Smugglers Collection, it can sell for at least 250 coins. Therefore, make sure to keep it in your bag no matter what. After that, continue with your day and complete all of the usual tasks.
Once you have finished everything, it is time to buy something new.
Buy The Oyster Kit

Purchasing these kits is also very important because they unlock new stations in your workshop, allowing you to restore items that you previously could not repair or improve. Therefore, purchase the Oyster Kit and the Oyster Station will be unlocked inside your workshop.
Once you have done that, start the next day and repeat the usual process.
Treasure Beach – Day 27, 28, 29, & 30 Walkthrough

During the next several days, from Day 27 through Day 29, do not focus too much on purchasing new upgrades. Instead, focus primarily on earning money. Use your tickets, sell your items, and build up a healthy amount of coins. Once you have done that and finally start Day 30, repeat the same process one more time.
By Day 30 or maybe 31, you should have cleared all of the pollutants from Whistle Island, meaning that you are now ready to unlock the third island in the game. However, before doing that, there are still a few upgrades that you should purchase.
Buy The Better Shovel And Even Better Shovel

You may have noticed that the speed at which your shovel digs through the sand is still quite slow. Therefore, you should purchase both of these upgrades to make the digging process much faster. Doing so will save you a significant amount of time every single day.
Now that you have cleared all of the pollutants from Whistle Island, you can obtain the permit that allows you to travel to Tropical Island. It is the third island in the game, so you will need some money available to purchase the permit. Also note that you can now visit the Animal Hospital as well because the requirement for unlocking it was clearing all of the pollutants from Whistle Island.
Head To The Animal Hospital
At the Animal Hospital, you can now bring injured animals that you discover on the beach. You may not have found any so far, but now that the hospital has been unlocked, you will begin encountering them from time to time. In addition, there are also animals at the hospital that accept donations.
You can donate money to these animals, and every donation rewards you with a ticket. At the moment, since you still need to purchase the island permit, you do not necessarily need to donate right away. You will earn plenty of money soon enough, and at that point, making donations will be much easier.
If you do have some extra money available, feel free to donate to the animals and then use the tickets you receive to potentially earn your money back, or perhaps even make more than you spent.
Buy The Tropical Island Permit
The Tropical Island Permit costs only 500 coins, so go ahead and purchase it. Doing so will unlock the third island in the game. Once that is done, you will be ready to start your next day on Tropical Island and continue your adventure.
With that, the walkthrough of Treasure Island, featuring days 11 – 30, comes to an end.
