Zero Flash

Sixteen digits, three minutes: link them, alternating plus and minus, to land right on zero, then challenge other players to a duel on the same grid. No ads.

Zero Flash is a numbers game: on a 4×4 grid, link neighboring digits, alternating plus and minus, to land right on zero. You have 3 minutes.

How to play • Trace a path of neighboring cells, in all 8 directions, never going through the same cell twice. • The first digit counts as plus, then you subtract and add in turn: 7 − 3 + 5 − 9 = 0. • A path of at least 2 cells that lands on zero scores points, the more the longer it is. • Start again from the last cell of a successful path to raise your multiplier. • Bonus cells double the points of the path that crosses them.

Challenge other players Take on other players in a duel on the same grid, each at their own pace.
