Number Duel Rules

How to Play Number Duel

Number Duel is a quick tactical board game built around numbers. Your goal is to claim the right cells and finish a winning line before your opponent.

Basic Turn Flow

  1. Choose a game mode and check whose turn it is.
  2. Check the center target and choose your active number when the mode has a number picker.
  3. Use the center target to find legal highlighted cells.
  4. Claim a highlighted legal cell, then build a winning line or combination.

Sum Duel

In Sum Duel, both players keep one active number. Add the two active numbers to create the center target. You can claim any open board cell with that matching sum.

Product Duel

In Product Duel, the two active numbers are multiplied instead of added. Choose a number, match the product, and claim the highlighted cell.

Fifteen Duel

In Fifteen Duel, there is no number picker. Claim any open number from 1 to 9. The first player to own three numbers that add to 15 wins.

Winning and Passing

In Sum Duel and Product Duel, connect four claimed cells horizontally, vertically, or diagonally to win. If no active number can create a legal claim, you may pass.
