Zero Numbers
A sliding-tile logic puzzle where you merge and cancel numbers to clear the whole board.

Controls
Drag a tile onto an adjacent tile with your mouse or finger to merge or cancel them.
How to Play
Zero Numbers is a number-elimination puzzle rather than a grid-filling sudoku. Every level starts with a small field of numbered tiles, and your job is to wipe the board clean. A tile can only move onto a neighbour directly beside it, so plan your route before you commit.
The rule that drives everything is simple: slide a tile onto an adjacent one, and if the two numbers match, both vanish. If they do not match, they add together into a single larger tile. The trick is to line up matching pairs, using sums along the way, until nothing is left. Clear the field and the next challenge unlocks.
Tips & Tricks
- Look for tiles that already share a value and cancel them early to open up space.
- Use additions deliberately: build a tile up to a number you know you can match later.
- Think one or two moves ahead, since a wrong merge can strand a tile with no partner.
Frequently Asked Questions
Is Zero Numbers a type of sudoku?
It sits in the wider logic-puzzle family and rewards the same careful thinking, but it is not classic sudoku. You merge and eliminate tiles to empty the board rather than filling a 9x9 grid.
What happens when two tiles do not match?
They combine into one tile whose value is the sum of the two. Matching tiles, by contrast, cancel each other out and disappear.
