Block Attack (Unknown manufacturer)

The idea of this game is to fill up the gaps in the randomly generated playing area with your 4 shapes of blocks. Similar to tetris except the blocks are completely controlled by you, and are not falling from the sky. As you start playing, a counter reduces from 9999 to 0 very quickly. When you complete the level, the counter stops, and that is the score you get. Unfortunately, as each level takes such a long time to fill in, you spend 5 minutes frantically pressing buttons, then end up with a disappointing 10 points or so.
