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.
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!
As you explore and solve puzzles, you'll visit a fiery volcano, an abandoned crypt, a secret ice shrine, and more exciting locations!
Uncover the secrets of the Mystery Boxes by unlocking and reading Maya's journal entries.
Collect badges by solving puzzles quickly, in few moves, or without using hints.
Complete 20 different challenges to unlock bonus cosmetic upgrades. Can you find them all?
