What are some multiplayer android games that are not *SLOW* turn based games ?

By slow, I mean 1 day+ for other players to submit their move. I'm looking more for games that are real-time, i'm not sure if they would be networked by bluetooth or over a regular tcp/ip connection. Like a tennis or soccer game for example. They don't have to be sports. Even a turn based game like chess or checkers would be fine as long as I see the opponents move pretty quickly after they made it. If this question is too ambiguous, vague, incomplete, or rhetorical, please comment and I will try to make it less so. Please do not close this, i'm really interested in finding answers to this. I'm happy to reword my question to make it more clear , just let me know.

• 2 Player Reactor is hillarious and frantic fun for two players. It is free unless you upgrade it to 4 Player Reactor. Mind you, you will all need to sit close to each other.

  It has limited replayability though, as you will soon figure out who has the fastest reflexes among your friends :P

  slim : finally, an answer that actually pertains to my question and not some advice how to use the site. I played this game. You're right, it is really fun. Thanks

• Cestos is a great free game that supports up 2-4 players online. It is turn-based in a sense, but all players participate during each turn which lasts for a maximum of 10 seconds.
