Lost City Checkpoint
Drain the Lake Lost City checkpoint: ruins, lava, chest side paths, Ancient Ruins badge, and Abyss approach.
Lost City Overview
Lost City features ruined structures, lingering lava hazard, and branching paths with chests that grant Gems. Reaching it awards Ancient Ruins for 110 Gems — one of the ten badges on the Ancient Bucket path.
Chest Side Paths
Optional detours spawn chests worth Gems. Each player can open chests independently in multiplayer. Lucky Find and Sunken Riches badges track chest totals.
Navigation
Balance Gem hunting with run pace if you are rushing Phone Ending. Veterans farm chests here for Diamond income.
Gear Check
S-tier buckets (Toxic, Dragon) make Lost City drainage significantly faster. Ancient Bucket is ideal if unlocked.
Final Push: Abyss
After Lost City machine progress, enter Abyss for the phone pickup and Find My Phone badge (140 Gems).
