All more fun with friends.

Classic number and math games you can play together — pick one, invite someone, and jump in. Each game has its own Elo leaderboard too.

Game How It Works Mode
Bulls & Cows
Turn-based
Take turns guessing each other's secret code. Each guess yields bulls (right digit, right position) and cows (right digit, wrong position). Configurable 3–6 digits.

Equation Duel
Turn-based
Wordle for math equations. A hidden equation is revealed through 6 guesses with colour hints. Every guess must itself be a valid equation.

Four numbers appear simultaneously. Use +, −, ×, ÷ to make exactly 24. First to get it right wins — great fun with friends who like a mental challenge.
