Blackjack Tournament

The tournament was run in two phases.

  • In phase 1, every player played 1000 games against my naive dealer.
  • In phase 2, every player played 1000 games against every other player in the tournament. In each phase, 10 rounds were completed.

    The games were scored as follows:
    game condition score (to player)
    both have blackjack (tie) 1
    player has blackjack, dealer went bust 2
    player has blackjack, dealer not bust 2
    player went bust, dealer has blackjack 0
    player went bust, dealer went bust 0
    player went bust, dealer not bust 0
    player not bust, dealer has blackjack 0
    player not bust, dealer bust 2
    player not bust, dealer not bust, tie score 1
    player not bust, dealer not bust, player closer to 21 2
    player not bust, dealer not bust, dealer closer to 21 0

    The top 5 players for the ten rounds (numbered 0 through 9) for each phase are shown here:

  • results of phase 1
  • results of phase 2

    To compute the tournament winners, a score was computed by taking the top 5 players from each round and subtracting their place within each round from 6. For example, a player who was in first place would receive a score of 5. A player in 5th place recieved a score of 1.

    A total score for each phase was computed. The results are shown below:
