The Competitive Math Card Game
Place your bets, roll the dice, beat the clock, and prove your math skills under pressure.
MathJack turns arithmetic into a high-energy casino-style strategy game where players use cards, operation dice, chips, and a timer to solve equations before time runs out.
Fast, Strategic, and Easy to Learn
Each round builds suspense in stages: ante, reveal the operation, raise the stakes, flip the second card, and race the timer.
The Ante
The dealer lays down the first card. Players decide whether to enter the round with at least one chip.
Operation Reveal
Roll the operation die to determine whether players add, subtract, multiply, or divide.
Raise the Stakes
Once the operation is known, players can increase their bet before the final card appears.
Race the Clock
The second card is revealed and the hourglass starts. Correct answer before time runs out wins the payout.
Game Equipment
MathJack uses a dedicated deck ranging from negative to positive values, operation dice for beginner and expert play, an hourglass timer, and betting chips to track the score.
