Jetpack for Brainrots Islands
Floating sky islands are the heart of Jetpack for Brainrots. Each tier gates Brainrot rarity, fuel cost, and guard difficulty. This map guide helps you plan every flight.

New Island (April 2026 Update)
The latest Saturday update added a new Apex-tier island hosting Meowl and Smurf Cat Exotic Brainrots. It sits above all previous Peak islands and requires Tier 5 jetpack (Rebirth 4) minimum for safe round trips.
Navigation Between Islands
Islands are not connected by bridges — jetpack flight is the only transport. Speed boost rings float between tiers on common flight paths. Learn the ring positions to save 10-15% fuel per trip.
Island Guard Difficulty
Guard speed scales with island tier. Starter guards are avoidable with basic steering. Apex guards require Tier 5+ speed and diagonal descent escapes. See our Avoid Guards Guide for tier-specific tactics.
