Number Games · Play With Friends
Bulls & Cows, Equation Duel, 24 Game, and Higher/Lower — invite a friend, pick a game, and have fun. Daily puzzles, Elo ratings, and leaderboards come along for the ride.
Take turns guessing each other's secret code. Each guess tells you bulls (right digit, right spot) and cows (right digit, wrong spot). 3–6 digits. Pure deduction, played together.
Wordle — but the answer is a math equation. Every guess must be a valid equation. 6 guesses to find it. Share your result and see how your friends did on the same puzzle.
Four numbers. Any operations. Make exactly 24. First to get it right wins — so it's a great laugh with friends who love a bit of mental maths.
Both players pick a secret number, then try to guess each other's with only higher/lower hints. Quick, simple, and surprisingly addictive to play with a friend.
One tap to challenge any friend. A lobby code pings their phone instantly. No waiting rooms, no matchmaking queue — just pick a game and jump in together.
Keep your daily puzzle streak alive and see how yours compares with friends. A small ritual that's more fun when you're doing it together.
Your match history with friends is always there — see who's up, who's behind, and who keeps asking for a rematch.
