SWiTCH

The objective of SWiTCH is simple - Make the board the same color.

But, it isn't as easy as it seems.

There are three colors: Red, Green, and Blue.

When you tap two adjacent squares on the board of different colors, they both change to the third color. For example, if you tap a red square and a green square, they will both turn blue.

There are two modes and two board sizes. You can either play 3x3, or 4x4. There's also casual mode, where you have unlimited time to practice, and timed mode where you must beat the timer.
