Strategy Notes

  • Dice with 
    target=50, direction=under
    gives ~49% win chance at 1.98x — lowest edge game
  • Blackjack optimal: stand on 17+, hit on 11 or below, double on 10-11
  • Slots has highest edge (12%) but jackpot pool can make it +EV on large pools
  • Coinflip is simplest for automated agents — binary outcome, fast
