About

Perion

Features
Read full description

Which Perion are you? Flying in TURBO, chasing PERFECT, or the one who never breaks a streak? One tap. That's it. But landing that tap at exactly the right moment is harder than you think — and far more satisfying. In Perion, the ring spins and you wait. Tap too early, it doesn't count. Tap too late, same thing. But nail that exact moment — PERFECT — and something in you says "one more." Even a MISS is oddly motivating, because it's usually close — you never know if the next one lands as GOOD, GREAT, or PERFECT. GET INTO TURBO Land enough hits in a row and TURBO kicks in. The screen shifts, everything speeds up, and suddenly you don't want to stop. Once TURBO grows, there's no going back — only forward. CATCH BRAVO Hit a 200 combo and BRAVO appears out of nowhere, exactly when you don't expect it. Extra shield, extra life. If you've got a Combo Shield, it forgives one mistake without breaking your streak. KEEP YOUR STREAK There's a daily streak, and yes, skip a day and it resets. Simple, but it works — it's one of the first things on your mind when you open your phone in the morning. Beat yesterday's score and the screen turns gold, and you can share that moment with a card. LISTEN TO IT An original soundtrack builds slowly over 90 seconds and explodes during TURBO. Not your average background music. Available in 10 languages: Turkish, English, Japanese, Korean, Spanish, Portuguese, French, Russian, Arabic, Italian. Download it, tap once, and let the rest happen.
