Number Challenge

You know the pen-and-paper game: one player sets a secret number, the other guesses, and little plus and minus clues point the way. This is that game on your phone. Same rules — except the person across from you is now a real opponent, from anywhere in the world. Set your 4-digit secret, then work out your opponent's from the clues: ➕ right digit, right place ➖ right digit, wrong place First to crack it wins. There's plenty beyond live matchmaking. Send a friend a room code and settle it in a private duel. Ranked mode gives you an ELO rating and leagues to climb, Bronze up to Diamond, with a leaderboard spot if you're good enough. No connection? Practice against bots on three difficulty levels. The deduction notepad keeps track of eliminated digits so your head doesn't have to — proper mastermind-style code breaking. Never played before? The tutorial teaches the rules inside a real two-minute match. No sign-up, no forms, no waiting. Download, set your number, play. The neon look comes in dark and light. Your rival has already started guessing.
