We wanted to create a puzzle game where the player could experiment with the perception of numbers; a game with simple rules which gives freedom for strategic thinking and exploration. Tallnum is not just a game but also a collaboration platform. We invited five incredible artist to join in and share their own visions of what a game could look like, each became a premium skin for the game. Tallnum is a puzzle game about numbers and the different ways one can perceive them. Players are taught how to control a set of numbers through simple swipe interactions and are encouraged to experiment with various strategies. By combining equal values together players can put their mental power to the test and try to beat the highest score.
