Game: Speed Cluster

I've found a new favourite flash game and it's called Speed Cluster. What you need to do in this game is stack the cards in the appropriate order. You can either go up or go down, e.g. 123 or 321 or KQJ or JQK. The more cards you stack, the more points and time you get. It'll make sense once you started playing. Oh, in case you're as slow as me, A stands for ace or 1. It had taken me awhile to figure that out. Anyway, my best score was 109270 at level 25.
