This game is good for wasting time, as hinted by the name. You need to do things like click specific coloured buttons, in a specific order to win each round. Every few rounds there is a checkpoint, which you'll go back to if you don't finish the current round.
This is quite a good game but it may frustrate some people. Our advice is if you keep losing then don't try to play the level, instead just watch whats happening so you know what to do.
