Num Null

Num Null is a number puzzle built on one idea: bring numbers together until they cancel out to zero, then clear the board.

Tap a tile, tap a neighbour, and watch the numbers merge. Make a zero and the cell turns Null. Slide numbers into empty cells, plan a few moves ahead, and finish with as many Nulls as you can in as few moves and as little time as possible.

PLAY YOUR WAY

• Casual: relaxed single-player boards at your own pace.
• Compete: a five-minute race against another player's board. Highest score wins, with head-to-head stats at the end.
• Custom: replay any board from its seed, or share a seed so a friend plays the exact same puzzle.
• Four board sizes, from a quick 3x3 to a deep 9x9.

POWER-UPS Undo your last move or Flip a number's sign when you are stuck. Earn bits from daily rewards and good runs, and spend them in the in-game store. Bits are a virtual in-game currency and cannot be bought with real money.
