Deuce rules

  • Each match consists of multiple games
  • On any game, if you win and your opponent busts, you get a point
  • Get two more points than your opponent to win the match
  • Gameplay is identical to contest mode in Solo, but rolls are entangled so that on each step, your roll is the same as your opponent's
Timer
  • Base timer: 60s
  • Increment: 10s/step entering steps 6–10, then 2s/step thereafter
  • As long as you don't time out, there's no advantage to finishing faster, so take your time!
