ZERO: Logic Puzzle Brain Game

Tap a tile. It flips together with its neighbours. Bring the whole board to ZERO.

ZERO is a calm, clever logic puzzle and brain game. Every tile is either a plus or a ZERO ring. Tap one and it flips along with the tiles its shape reaches: a plus flips up, down, left and right, a cross flips its diagonals, a corner flips two tiles in an L. One tap can fix a row – or undo three good moves. Find the order that clears the board.

LEARN IN ONE MINUTE
A short hands-on tutorial teaches the rules on tiny boards. No walls of text: tap, watch, understand.

500 LEVELS
Start with a single tile and work up to boards that mix plus, cross and corner tiles, gaps that stop the effect and locked tiles you can only change through their neighbours. Every level has a move target: reach it for three stars, finish without hints for a diamond.

A NEW DAILY PUZZLE EVERY DAY
Five rounds, sixty seconds each. Fewer moves and faster solves score more points. Finish all five rounds to keep your streak alive.

ENDLESS PRACTICE
Finish level 30 and endless practice opens: fresh puzzles for as long as you like, with the shortest solution one tap away.
