Guide: Installing Mystery Boxes on Linux with Steam Proton

This guide describes how to use Steam Proton to play and run Windows games on your Linux computer. Some games may not work or may break because Steam Proton is still at a very early stage.

1. Activating Steam Proton for Linux:
Proton is integrated into the Steam Client with "Steam Play." To activate proton, go into your steam client and click on Steam in the upper right corner. Then click on settings to open a new window. From here, click on the Steam Play button at the bottom of the panel. Click "Enable Steam Play for Supported Titles."

Alternatively: Go to Steam > Settings > Steam Play and turn on the "Enable Steam Play for Supported Titles" option.

Valve has tested and fixed some Steam titles and you will now be able to play most of them. However, if you want to go further and play titles that even Valve hasn't tested, toggle the "Enable Steam Play for all titles" option.

2. Choose a version
You should use the Steam Proton version recommended by Steam: 3.7-8. This is the most stable version of Steam Proton at the moment.

3. Restart your Steam
After you have successfully activated Steam Proton, click "OK" and Steam will ask you to restart it for the changes to take effect. Restart it. Your computer will now play all of steam's whitelisted games seamlessly.

4. Launch Stardew Valley on Linux:
Before you can use Steam Proton, you must first download the Stardew Valley Windows game from Steam. When you download Stardew Valley for the first time, you will notice that the download size is slightly larger than the size of the game.
This happens because Steam will download your chosen Steam Proton version with this game as well. After the download is complete, simply click the "Play" button.

What is Mystery Boxes? Features and Description

Mystery Boxes is a codebreaking puzzle game. Send 4-digit signals to a mysterious artifact, which will respond with another sequence. Look for patterns in the responses to identify the rules, then use this information to produce the target response.

Help intrepid explorer Maya Robinson investigate a set of ancient cube-like artifacts buried deep in the jungle!

When you send a 4-digit signal to the Mystery Box, it will transform it according to a set of secret rules.

Sending 1234 to the box might give you 8642.
Sending another number, like 2244, gives you a different result like 8844.
Through experimentation and deduction, you can figure out the rules: in this case, double each digit, then flip the number backwards.

Once you figure out the rules, use them to obtain the target. With the rules above, what input would produce 6424?

Each rule creates a particular pattern of digits. Seems simple enough, right? But there's a catch: each box has multiple rules! The box takes the result of the first rule and applies a second rule to it. Can you find the patterns and use them to activate the boxes? As you progress, boxes will have more rules of increasing complexity.

Maya is also happy to assist you as you solve the puzzles. She'll give you assistance with more challenging rules, give you ideas of possible solutions, and offer you tips and advice. If you get stumped, don't be afraid to ask her for a hint!
