Try and remove all the blocks from the screen. Sounds easy does not it - but you'd be wrong! Pit your wits versus Standard mode and see if you can progress to the higher levels of play. Raise your game and play Countdown mode with limited time to make each move. Take too long and it's game over! When you are ready try Survival mode which is fast and frantic as you try and stop blocks building up to the top of the screen.
