FAQ

How many digits can I play with? +

Choose 4 digits for a shorter sequence or 6 for a longer one. Start with 4 if you’re new.

Can I adjust the pace and motion? +

On iPhone, you can turn off the time limit, reduce motion, and adjust sound in Settings. Regular Watch rounds start with a 3.5-second memory countdown. A valid challenge notification goes straight to the number pad. Watch animations follow the watchOS Reduce Motion setting.

How do challenge notifications work? +

They’re optional. Turn them on and choose their timing in Settings. Notification challenges don’t count toward the regular leaderboards. The app schedules up to 7 days of challenges and adds more when you open or return to it. Delivery depends on your device settings and conditions.

Does LOOPT use real authentication codes? +

No. All numbers are generated for the game. LOOPT doesn’t generate or store real authentication codes or OTP secret keys.

What can I do on Apple Watch? +

Play 4- or 6-digit rounds for free, with no ads or in-app purchases. Each round ends with a result. Tap ↻ on the right for a new round with the same number of digits, or × on the left to choose 4 or 6 again. Open a valid challenge notification forwarded from your iPhone to enter those same digits immediately. The Watch won’t show the number again. Leaderboards and the Remove Ads purchase are available on iPhone. Notification delivery depends on OS settings and conditions.
