How to Play Maths Warriors

Maths Warriors is a two-player dice battle game where mental arithmetic wins fights. Each player commands six polyhedral dice and must capture all of the opponent's dice to win — using raw strength or clever arithmetic expressions.

The Dice

Each player starts with one complete set of six dice:

D41–4
D61–6
D81–8
D101–10
D121–12
D201–20

Each die shows a random value within its range. Values re-roll after attacks, so the board state changes every turn.

Objective

Capture all 6 of your opponent's dice to win. When you capture a die it leaves their side of the board permanently. Whoever loses all 6 dice first loses the match.

Who Goes First?

At the start of each game, both players' dice are sorted smallest to largest and compared index-by-index. The first player whose corresponding die is smaller goes first. If all six pairs are equal, a tiebreaker roll decides.

Going first comes with the First Player Penalty on the final move — see below.

Attack Types

Strength Attack

Select one of your dice and target one of your opponent's dice. Your die's current value must be greater than or equal to (≥) the target's value. If successful, you capture their die and your attacking die re-rolls.

Example

Your D12 shows 9. Opponent's D8 shows 7. 9 ≥ 7 — Strength Attack succeeds. You capture their D8; your D12 re-rolls to a new random value.

Mind Attack

Select two or more of your own dice and combine them using arithmetic operators (+, −, ×, ÷ and parentheses) to form an expression that exactly equals the value of the target opponent die. All dice used in the expression re-roll on success.

Example

Opponent's D20 shows 18. You have D6=3 and D8=6. Expression: 3 × 6 = 18 — exactly equals the target. Mind Attack succeeds: you capture their D20, and both your D6 and D8 re-roll.

Advanced Example — Three dice

Target is 7. You have D4=2, D6=4, D8=3. Expression: (2 + 3) + 4 / 4... or more simply 4 + 3 × (2 − 1). Any valid expression evaluating to 7 works — you can use as many of your own dice as you need.

First Player Penalty

The player who goes first has one handicap: their final capture (the move that would win the game) must use a value strictly greater than (>) the target, not just ≥. This applies to both Strength and Mind Attacks on the last remaining opponent die.

This rule prevents the first player from having too large a structural advantage.

Winning

The first player to capture all 6 opponent dice wins. If the game timer expires first, the player with fewer remaining opponent dice wins. A tie in dice count goes to the non-starting player.

Strategy Tips

Timer

Games have a configurable overall timer (default: 12 minutes). When it runs out, the player with fewer opponent dice remaining wins. You can also set an optional per-move timer to keep turns snappy in competitive play (default: off).
