Lost City

Lost City is checkpoint 5 of 7 in Drain the Lake — ruined buildings surfacing on the lakebed. Reaching it awards the Ancient Ruins badge worth 110 Gems, and it becomes a respawn point so a swim or a Shark no longer sends you back to the start.

2,905,860 players have reached it — about 58% of everyone who has drained a first bucket, down from 64% at the Molten.

Reaching the Lost City

Ruined buildings and ancient structures surface on the lakebed. Seeing them nearby is the community cue that the bottom — and the phone — is close. This is a late-run checkpoint where downtime is expensive.

When the Lost City ruins rise around you, the finish is near — so stop tinkering and just drain. This deep, every wasted second is a far longer trip than it was near the surface, so skip detours and hold the fill-and-pour rhythm straight to the Abyss.
