The rules of Puzzle Battle are simple:

  • Solve as many puzzles as you can in the given amount of time.
  • Each puzzle gets harder as you go.
  • Three strikes and you’re out.
  • Solve more puzzles than your opponent to win.
  • You and your opponent receive the same puzzles in the same order—so no excuses!
