ZeroOut
Slide boxes together until only one is left.
How to play
- Boxes move like a chess rook: any distance along a row or column, but never past another box.
- Tap a box, then a marked square. Or swipe the box, or use the arrow keys, to slide it all the way.
- When a box runs into another box, they merge into one box and their numbers add up.
- If the new number ends in 0, the zeros drop off: 23 + 37 = 60 becomes 6.
- Double-tap a box (or press S) to break it in half: 14 becomes 7 and 7, and 7 becomes 3 and 4. The new half goes on a free square next to it, and a split counts as a move.
- Merge everything into one box in as few moves as you can. Boxes that add up to 10 share a color.
