Tap the moment the needle touches the dot. One tap, perfect timing, and the lock clicks open. Unlock Circle is back with its biggest update since 2016. The original one-tap reflex game is still here as Classic, now joined by four new modes, seven target types, boss locks and a Daily Lock that everyone plays together. How to play • A needle spins around the ring. Tap the moment it touches the dot. • Missed? You'll see how many milliseconds too early you tapped, or why the run ended. Five modes • Classic: the original 2016 game. Every hit is a move, and one miss ends the run. • Endless+: hit the white center of the dot for a Perfect. Build your combo up to ×4, and land 8 Perfects in a row to fire up fever mode. • Rhythm: targets land on the beat of the music, and the tempo keeps rising. • Daily Lock: the same lock for everyone, one scored attempt a day. Keep your streak alive and share your result. • Locks: 8 worlds × 10 stages, 80 stages in all. Earn up to 3 stars on every stage and beat the boss lock at the end of each world. Seven target types • Dot, double dot, sliding dot, trap, arc (press and hold), shield (two hits) and direction arrow. • In the Treasure Vault you play with two rings and two needles. Collect and unlock • Collect keys and unlock new needle styles. • Defeat bosses to grow your lock collection. • Three daily quests, achievements and Game Center leaderboards.
