Dialed is a one-tap precision game: a needle sweeps back and forth across a dial, and you tap the instant it lands inside the zone. Land dead center for a PERFECT and keep the run alive at full value. Chain PERFECTs back-to-back to build a streak bonus. Miss the zone entirely and the run is over. Easy to grasp, hard to master: • One tap, no hidden rules • Land dead center for a PERFECT — chain them into a streak bonus • The zone narrows and the pace quickens gradually, so the first runs are forgiving and mastery is earned over time • Your best score is saved automatically on your device • Sound and haptic feedback on every tap, toggle them off in Settings No account required, no personal data collected — just get dialed in.
