Good free games you play for a long time?

Damn can't beat your score XD already played around 10 times, my best was 073540 :/ .

But nice game . 2 years! Do you play any other version of tetris? There are bunch from slow to fast paced Tetris.

Actually I just play this one :O
I've tried others, but somehow this stuck with me. Whenever I play another version of tetris it just seems so unexciting and static (?) to play.

Hmm there are a bunch of Tetris games which are dynamic to play.
Fast paced: Cultris II: classic, time & piece-based combo, Tetris Friends: guideline, T-Spin
Slow paced: Ntris (multiplayer mode is fast paced though): 5 piece previews + hold, larger pieces on higher levels (or as a result of attacks in multiplayer)
Turn based: King of Stackers: All spins, 5 piece previews + hold - but bah, 'they' are way better than me.

And hey, guys, thanks! Now I have so many games to try :P .

Forgot to mention that I also like 2d / curtain shooting games, i.e. bullet hell, but I prefer games with slower and denser bullets rather than sparser but faster ones.
