We've created a virtual online currency called Arcade Bucks.  Each of our games costs a certain amount to play, and the game's owner will be credited that same amount.  Temporarily, players will gain 5 Arcade Bucks for successfully submitting a score, and owners will be credited 2 Arcade Bucks.  Shortly, we'll be releasing our next major enhancement.  Which will be a variable reward for successfully submitting a score that's based on how well you played the game.  Game owners will receive a flat 10 Arcade Bucks, which will match the new cost for playing a game.  So, soon it will cost you 10 Arcade Bucks to play a game, but you'll have a chance to win up to 100 Arcade Bucks for playing the game well.
