Slide and rotate the tiles to combine them according to the rules of algebra. Try and make a tile whose value matches the outlined target value.

How to play:

• Use the arrow keys to move all tiles in the direction of the arrow.
• When three tiles that form a valid algebraic expression touch, they are automatically simplified.
• If two equal operators touch, they merge into one.
• Clicking a tile or grid cell will rotate all tiles in that quarter of the board in a clockwise direction.
