Zero Flash
Zero Flash is a numbers game for Android and iOS: link neighboring digits on a 4×4 grid, alternating plus and minus, to land right on zero, against the clock, and challenge your friends to duels on the same grid.
Duels count in the leaderboard of the month. They are played with diamonds, given on each day you open the game; practice is free, within a number of games a day.
No ads. The game is free, with optional purchases in its shop: the Double Pack, the 30-Day Pass and the 50-Diamond Reserve.
