Every tile on the board holds a number from 1–5. The tray below holds adjustment chips.
Drag a chip from the tray and drop it onto any tile on the grid.
The chip's value is added or subtracted from that tile's number (numbers stay between 1–5).
If that move lines up 3 or more matching numbers in a row or column, they clear, you score,
and a new chip joins the tray!
No match? The chip is still used up. Run out of chips and it's game over — so plan each drop wisely.
