Slide Merge · Number Merge Puzzle
Slide Merge is a sliding number puzzle on a 4x4 tray: every swipe pushes all tiles as far as they go and equal numbers merge into their sum. A new tile appears after every move, so plan ahead and keep the tray from jamming.
How to play Slide Merge
- Swipe or press an arrow key to slide every tile in that direction.
- Two equal tiles that collide merge into one tile worth their sum.
- The run ends when the tray is full and no tiles can merge.
Controls
Swipe — or arrow keys / WASD.
Tips & tricks
- Keep your biggest tile in one corner and build a chain of decreasing tiles beside it.
- Avoid the one direction that would pull your big tile out of its corner.
