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).

- Merge matching parts to create better items

The forge never stops. Even when you do. Merge two matching parts and they fuse into something better — scrap into bolts, bolts into circuits, all the way up to the Nexus. Every merge pays out, and the game keeps banking coins while you're away. Come back to a pile of offline income. Spend it. Watch the numbers climb. Do it again. WHY PLAYERS KEEP COMING BACK: • Eight tiers of gear to chase, from Scrap to Nexus Core • Colossal Dreadnought Titan Raids — breach compartments for Titan Cores • Autonomous Drone Fleet — send probes on deep-space salvage expeditions • Offline earnings and passive income that reward you for logging in • Dynamic Anomaly Storms triggering cosmic nova chain reactions • Weekly season pass — free and premium reward tracks • Prestige mechanics for permanent multipliers on all salvage yields • Contracts, syndicate black market tech, and daily bonuses always stacking • Upgrades that make every single coin and merge worth more No energy meters. No timers between merges. Tap, fuse, grow. Free to play. Rewarded ads are optional and only ever boost your coins.
