Touch Extreme is Slap Jack without the long wait. Every card gives you a chance to earn a point. Hit the button with the suit that matches the over turned card before your opponent and you get the point.
Tip: For higher scores, pick slower opponents. :)
If this isn't challenging enough use your one throwing star when you see a joker. Hit any button when you see the black joker and wipe out your opponents score. But be careful, hit any button when the red joker appears and you'll be wiping out your own score.
This game has a single player mode for improving your speed when you can't convince someone else to play.
The Japanese temple is the home button so you can bail out if the pressure gets too great.
