Sprinter is a classic "tap-to-run" game. I found this one very easy to play against the programmed opponents. Competing with a human is a must! Whacker is a variant of whac-a-mole with a few extras - higher point moles, skulls that deduct points and lightnings that kill all moles at once.
The Balloon Pop is a classic too. Some of the Balloons explode in smaller Balloons and some of them are dangerous and take a life. The Math Game is a basic math operation game with a timer. Again, it's much more fun with a human opponent.
The Mail Sorter will test your reaction time and attention to detail. Your task is to sort packages and letters to three pigeon-holes. This game is challenging. The packages and letters don't differ that much...
By far the most interesting game for me is the Samurai Duel. It tests reaction only and it's quite exciting for a game that only needs one tap! Two samurais are standing in front of each other and two red bars start to grow. When they touch, the sword icon will dissapear and reappear randomly on the screen. If you tap it fast enough, you win.
The last but not least is the Fencing game. It challenges your reaction and orientation as well. The goal is to score point by touching the correct green light followed by another green light in a very short time limit. If you make a mistake, you have a chance to parry the opponent's attack. Two mistakes and opponent will score a point.
All the games are quite nice and entertaining, if you like these simple games. The advantage is that you have them all in one game. The addition of bluetooth multiplayer makes the games much more fun if you have a human opponent to compete against. Some of the games in single player could use a difficulty setting. When you master them, thet might get too easy.
