Kod4

Challenge your friends or bots in an unforgettable number-guessing battle. Guess the secret 4-digit code before your opponent does!

KOD4 is a real-time 1v1 strategy game built on the classic "bulls and cows" logic.

How to Play Each player picks a secret 4-digit number. You take turns guessing your opponent's number. After each guess, you get feedback: + means the right digit in the right position, - means the right digit in the wrong position. The player who cracks the number in the fewest guesses wins.

Real-Time Gameplay You follow your opponent's moves live as they happen. Each round is timed — think fast, guess smart.

Social Features Add friends and set up private matches. In-game text chat, friend leaderboards, and a global ranking board keep the competition alive.
