Sell Lemons has many hidden secrets, and the Sewer Map is one of them. It is a full underground sub-area that contains four mazes. Now, as you can expect, the hidden maze comes with some secret rewards, and to get them, you must learn completely about the map. Here is a full breakdown of the Sell Lemons Sewer Map, so you know about all the levers, keys, and rewards locations.

The sewer is located under the map you play Sell Lemons in. To get there, stand on any of the street manholes. Once you drop in, there will be four lanes and a leaderboard section in the center.
