Whoops! I thought this was a game about my grandma.
That sounds like BreakDown for mobile phones. I'll definitely try it.It's a PC game ported to DS. Basically, blocks rise and I think it's like, if three or more like color blocks are touching, you can click them to clear the blocks. The more you clear at one time the more points you get. As levels go up it gets faster and faster.
There are also probably some more modes in this game than originally on the PC.
