Ten Seconds To Symmetry

Find the error out of the many colors covering the screen. Tap the single square that is different, (or its neighbor,) to continue. Be careful, for there is limited time, and the grids will only get more challenging.
The grid gets bigger for a few rounds, then a new color joins the game.

In Versus mode, play against a friend on the same device. Place it between you and pick a side. Player with the most points when the timer runs out wins.
