STOP IT DEAD ON. You get a number — say 15:00:00. Press GO. The clock runs completely blind. Count the seconds in your head, then press STOP dead on the number. ±5ms is a PERFECT: confetti, screen shake, x10 points, full dopamine. That's the whole game. It's also the hardest thing you'll do today. SOLO Endless rounds, random targets from 1 to 15 seconds. Build CLEAN-or-better streaks. Chase your first PERFECT — then nine more (the 24K gold button waits at ten). 1V1 DUELS Same number, same nerve — closest average over 3 rounds takes the W. Ties go to sudden death. • COUCH — split screen, one phone, two thumbs • VS BOT — rookie, solid, or cracked practice bots • ONLINE CASUAL — quick matches worldwide • RANKED — RP on the line, protected by fair-play detection: matches with beyond-human precision are voided automatically and never move RP. • CHALLENGE LINKS — hit a monster score, send the receipt. Friends tap your link and run the exact same number. Bet they can't. IMPOSTER (3–6 PLAYERS) Everyone sees the target… except one of you. Run the clock one at a time — every time stays sealed until the vote — then vote out whoever's faking it. Play online (3–4 players) or pass one phone around the party. Ties let the imposter slide. MAKE IT YOURS Button skins (SLIME, LAVA, HOLO, GLITCH, more), LED clock faces (MOLTEN, CRYO, VAPORWAVE, more) and arena backdrops. Opponents see your equipped skin — that's the flex. Some things can't be bought: the 24K gold button (hit 10 PERFECTs), THE PERFECTIONIST clock (25,000 points, earned by playing) and the UNDEFEATED clock (15 online wins). GAME CENTER Leaderboards for ranked RP and best average, plus achievements to grind. Your internal clock is worse than you think. Prove us wrong.
