Equations

Equations is a phase-based math card game where you build valid mathematical equations from digit and symbol cards.

Every phase asks for a longer equation than the last, starting at just 3 cards and building to 10. Clear all the phases to win. It's designed to be winnable but tight: a sharp player will win often, a careless one will get stuck.

WHY IT'S DIFFERENT

• Real math, not "close enough." Every completed equation is checked for validity — proper PEMDAS order and correct multi-digit numbers.

• Every placement is a commitment. Cards you play can never leave the board, and slots fill in from the ends only. One rushed move can cost you the round.

• Escalating challenge. Early phases teach the basics with simple comparisons; later phases demand multiple operators, parentheses, exponents, and factorials.
