It's simple: A mysterious box is locked with a 4 to 8-digit code. Your only goal is to open it—with your own hands.
No hints. No puzzles. But who needs them? If you try every number up to 9999... eventually, it will open.
This is a game about perseverance, pattern, and reward. Can you crack the code?

If the input matches the code, the chest opens. Game cleared—and you earn generous rewards!
Though there are no hints, coins and gems will occasionally fall during gameplay. These can be spent on optional skills to boost your efficiency just a little.
The longer the code, the greater the reward.
Clearing without using any skills also boosts your final reward.
In Serious Mode, all skills are disabled. But in return, the rewards skyrocket.
This mode is designed for players who want maximum challenge and maximum payout. Clearing this mode also counts as completing Normal Mode for Steam achievements.
A short, basic tutorial is included.
