Drag the blocks and fill up the grids in Color Blocks. You’ll start with an empty grid and three blocks to add to it. When you’ve finished placing them, another three will appear. Plan your strategy, because part of the grid will clear when you get a full column or row, but you need to be careful to not leave gaps. How long can you play for before you can’t place a block? Color Blocks is easy to play and highly addictive. It’s now unblocked in HTML5 and you can play for free on PlaygamePA. Play Color Blocks now on PlaygamePA!
