Drag and arrange the boxes of the same color in a row of 3 (vertically, horizontally or diagonally) and clear the boxes of that color. Stack 3 of the same color on the same grid and get the grid cleared. Easy and addictive gameplay!
It's well-designed, it looks good and it manages to be both original and fun to play. Plus, you can use the power-ups (changing the given box and refill by watching an ad)
