Abstract: A computer implemented method, system, and software for an online gaming system to permit users to measure and improve their skill at playing games that include both chance and skill by competing against computer system players (directly or indirectly), and then comparing their performance against another user who has played an identical game. Games may comprise: cards (i.e., poker and blackjack), roulette, craps, backgammon, and chess. In SkillBet™, users play against computer players in identical games, and then compare their game results against the other users. Because users are presented the same game options as the other users, the winner is determined by the user's superior skill In Total Skill, users play a game against each other, while duplicate computer players play an identical game. The winner is the user who outperformed his/her duplicate computer player.
