Three Keys is a timed door-picking game where the goal is to collect three keys before the timer runs out.
Each round starts with a 60-second timer and a grid of doors. Tap a door to reveal what is behind it: a key, an empty result, or a trap.
The game shows your current progress, including keys collected, attempts, and time left. Traps reduce the remaining time by 5 seconds.
You win by collecting 3 keys before the timer ends. If time runs out first, the round is lost.
The Door Map section lets you choose door packs. Each pack can change the result chances, such as more traps or more empty doors. Packs can show locked or unlocked status and save the best result.
