Competitive Number Games
Bulls & Cows, Equation Duel, 24 Game, and Higher/Lower — with real Elo ratings, friend rivalries, win streaks, and daily puzzles. Not a game collection. A competitive platform.
Crack your opponent's secret code before they crack yours. Each guess reveals bulls (right digit, right spot) and cows (right digit, wrong spot). 3–6 digits. Pure deduction.
Wordle — but the answer is a math equation. Every guess must itself be a valid equation. 6 guesses to find it. Your arithmetic instincts vs. your opponent's.
Four numbers. Any operations. Make exactly 24 faster than your opponent. No turns — first correct answer wins. Pure speed and arithmetic creativity.
Both players pick a secret number. Race to guess the opponent's number with only higher/lower feedback. The fewer guesses you need, the better.
One tap to challenge any online friend. A lobby code pings their phone instantly. No waiting rooms, no matchmaking queue — just you and them.
Consecutive wins tracked per game type and globally. Streaks reset on a single loss. Defend it, or watch it burn.
Players you've gone back and forth with become rivals. Your head-to-head record is front and center every time you meet.
