Enter the thrilling world of Obby: +1 Shrink for Running! Dash across the arena, shrinking with each step — from a giant to a tiny tot, then to micro, nano, and finally, reach the status of a shrink god.
Five walls with increasingly narrow gaps lie ahead. Only the smallest can slip through. Each wall guards a money plate — step on it, collect coins, and return to the start to face the next challenge.
Use your coins wisely: unlock 15 unique trails (from smoke to purple lightning), snag awesome skins, and get pets that help you earn more coins. The tinier you become, the more valuable the plates and the harder the gaps get.
Rebirth to increase your level cap and shrink even further — down to just 15% of your original size. Discover portals to frost and fire worlds, tackle tighter walls, and claim plates worth hundreds of thousands.
Climb the leaderboards for shrink, coins, and time, visit daily for rewards, and grab playtime gifts. If you slip up, just run to the next challenge!
