Objective

Fire numbered tiles up into five columns and match equal numbers to merge them into double. Tiles touching an equal number above, beside or below merge, and merges can chain into big combos. Every few shots a new row of tiles drops from the ceiling, so keep every stack below the red danger line and chase a high score.

How to play

1. Move your cursor (or tap) over one of the five columns, or press the left and right arrow keys, to choose where to shoot.
2. Click, tap or press Space to fire the loaded tile — it sticks to the bottom of that column.
3. When a tile touches an equal number above, beside or below it, they merge into one tile with double the value. Merges can chain into combos for bigger points.
4. Watch the "Next row in" counter: when it hits zero a new row of tiles drops in from the top and pushes every stack down.
5. If any stack reaches the red danger row the run ends. Clear every tile for a 500-point bonus.
