Blocker

User Summary Blocker is one of those addictive games with coloured blocks filling a grid. Click on groups of three or more blocks that are the same colour to remove them from the grid. As time passes, more blocks arrive from below, pushing the existing blocks up. If any one column gets too high, the game ends. There are a fixed number of lines per level so you can see how far you've got to go before the next level. As the game progresses it gets faster; there's a bonus level every fifth level; there are special types of blocks on later levels too.
