In CPK and RNS a user sets a score challenge max amount, game type (kills, assists, points, placement, win, rank) and game then enters into a match. This activates an open "Challenge", an invitation and automated acceptance of participation into an open Player to Player contest. Upon entering a match Challenger will detect any other users with active matches and notify the participants of the new Challenge. Scores are tracked and funds transferred to the winner. A score is identified as a scenario in which two players interact in a complementary in game event, such as when Player 1 kills Player 2 in a multi-player First Person Shooter (FPS). In this scenario Player 1 would win the challenge and Player 2 would be debited. Both Players immediately enter into another Challenge. Like all of our game modes, there are no fees charged for either of the Challenge types.
