Can you find the 5 digits before your friend does? NumBool is a challenging multiplayer logic game. It takes a lot of logical thinking to win (and a tiny bit of luck won't hurt either). Each player picks 5 distinct digits in the beginning of a game. The goal is to guess the digits your opponent picked in the exact order. Both players make a guess each round and get feedback accordingly. Whoever guesses the other's digits first wins. NumBool features: • Ability to add your friends and challenge them. • A practice area in which you can hone your logical skills without any rush. • A ranking table to compare your stats against your friends. • Matchmaking feature (will be unlocked once you beat the game in practice hard mode).
