Click on groups of colored blocks to remove them and earn points. Keep playing through levels and earning points for as long as you can.

An addictive puzzle game

Rainbow Blocks has many similarities to a game called Toon Blast. You have to click on groups of blocks with matching colors. You may also click on spinning rainbow blocks, which then randomize the surrounding blocks. Win the game by removing all the groups of blocks, or by removing all the rainbow blocks. You have to complete the level and get as much of the area cleared as possible to earn more points.

Only as addictive as you make it

Rainbow Blocks has been criticized for being a waste of time because all you do is remove blocks, but there are a great many games that are similar that were brought out before this game was released, and many of those were popular. Rainbow Blocks is similar to JT's Blocks and SameGame. The reason some people do not like Rainbow Blocks is because there is no way to win. You have to clear as many blocks as you can in order to score points, but all you ever do is progress to harder and harder levels. It is similar to Tetris in that you cannot complete it, you can only get higher and higher points before the game becomes too difficult to continue.
