AR exploration tips — get more out of the camera mode
The AR catch screen has a handful of quality-of-life tricks most players miss. Lock-on, ring timing, and the catch-bonus stack are the big three.
Why AR matters The AR catch screen is where Brain Rot IRL earns its name. Every wild Rotmon is rendered into your phone's live camera feed at a real-world position. Throws use device motion data — flick your phone forward like you're underhand-tossing — and the catch ring tightens on a fixed cadence regardless of frame rate.
Lock-on Tap and hold the Rotmon for half a second to lock the AR position. Locked Rotmons don't drift between frames and won't strafe out of view when your phone's gyroscope twitches. Always lock before throwing.
Catch ring timing The ring tightens twice per second to its smallest point, then opens again. A throw landed at the smallest ring is a "critical catch" (+100% catch chance, 2x XP). Watch the ring for two full cycles before throwing — it's the single biggest skill ceiling in the game.
The catch-bonus stack Five small bonuses stack multiplicatively on every successful catch: 1. Critical catch (center ring) — +100% XP 2. Curveball (flick with a twist) — +20% XP 3. Streak bonus (consecutive catches without a miss) — up to +50% XP at 10 catches 4. Daily quest bonus — +25% XP if the catch satisfies an active quest 5. Limited passive — +5% per Limited Edition in your dex
Players who optimise the full stack end up with effective XP gains roughly 3x higher than casual play.
AR view best practices - Hold the phone in landscape for the widest catch ring. - Stand still during the throw — walking introduces motion-data noise. - Move into open areas before throwing Ultras. The Rotmon needs visible ground around it for the lock-on to stabilise. - Charge your phone. AR mode is the heaviest battery draw in the game by a wide margin.
Common AR issues and fixes - **Rotmon won't appear:** restart the camera permission from your browser settings. iOS Safari sometimes drops camera access between sessions. - **Lock-on is unstable:** point at a textured surface (carpet, grass, gravel) rather than a flat wall. AR tracking needs texture to anchor. - **Throws feel laggy:** close other browser tabs. AR mode is sensitive to memory pressure.
