http://gameserpent.com/playgame/3267/Three-SevenThree-Seven is a tetris-like number crunching game. Similar to tetris in the fact that blocks drop down and you have to construct them in a way to eliminate blocks.
The game glitches on certain sequences of numbers that add up to 7 (for example, one row horizontally and one row verticlaly of 3 blocks will add up to 7 each but none of the blocks eliminate) and there are occassions where having three 7s horizontally or vertically doesn't eliminate the blocks.
Also I think it's pretty stupid that the blocks don't drop to the bottom when you clear them, why are they just floating there preventing you from getting a workable graph? It's nigh impossible to play an efficient game with blocks that don't fall to the bottom. I used to have nightmares if blocks in tetris would act that way... HOW COULD I EVER CLEAR THEM??
Such a sloppily written program, it's a shame this game could be really fun.
