To move the tiles, swipe up, down, left, or right. A swipe with three similar tiles in a row or column will score and merge the three tiles into a single tile with three times the value. On a scoring move, the two tiles that are eliminated are replaced with randomly placed "5 tiles." A non-scoring swipe will add a new "5 tile" at a random location.

A swipe with two or more scoring rows or columns will populate fewer "5 tiles" as a bonus. Also, a swipe with a full row or column of identical tiles will populate even fewer "5 tiles" as an extra bonus.

The game ends when there are no more scoring or non-scoring swipes on the board. A good game will last about 10 minutes and can achieve upward of 20,000 points.
