Well you're thinking.. It looks very nice but how do you play it? The idea of the game is that blocks fall down the screen. They fall as combinations of jewels and blocks. If you get a row of jewels or blocks all the way across your play area the line disappears. Jewels can also be removed however, by surrounding them on four sides with blocks or the wall. A little bit confusing? Maybe, but when you get going its great fun, plays right like a cute tetris, and is by Taito - so how can you go wrong?
