**Simple rules. Memorize the number, then type it back in the same order.**
A number appears on screen. Once it hides, tap it back in order on the custom number pad. Every correct answer adds another digit, so it keeps getting tougher. Miss, and you lose a life—run out and the game ends. How many digits can you reach?
Quick to play and easy to pick up, Kioku is a number-memory game made for short breaks and chasing a new high score. Perfect for the commute or any spare moment.
