At my arcade olympics tournament games site there is a different game tournament run each month with a $5 prize given to the winner for that month. The game to beat this month is called "Spear Toss" and registration on the site is FREE, so it will never cost you anything to play in the contest. Check it out and have fun playing games!!
Let me know if there's a broken link, but all the tournament games work fine and have been tested by all the players. The game play is at the bottom of the screen, so you have to go there to see the game.
