Lost City - Day 22

Lost City - Day 22 is the 22nd level of Lost City. It is the first level with trap tiles, and it does not contain any Gold Tiles.

Strategies
See below for a video walkthrough.

The provided Puff-shrooms should not actually be used to attack the zombies; rather, they should be used to trigger Trap Tiles. Excavator Zombies should always be taken out with Trap Tiles, as none of the plants provided can defeat them. Iceberg Lettuce and Stallia can be used to slow down zombies, gathering them into groups for you to attack with Trap Tiles.

It is possible to win by only using trap tiles to kill zombies, by placing your plants on the trap tiles when the zombies come.

Trivia

 * Like Wild West - Day 10 and Far Future - Day 19, it has two flags despite showing only one.
