Trap tiles are environment modifiers in Plants vs. Zombies 2 and appear in some Locked and Loaded levels, including Lost City's boss battle. In contrast with Gold Tiles, trap tiles bring detrimental factors to both plants and zombies. However, the player can use them as their own advantage. They are triggered when a zombie steps on it, a plant is planted on it, or when Dr. Zomboss drops a sandbag in boss battle.
There are two types of trap tiles: one with an icon of a flame on it and one with a rolling rock on it. The one with the rock summons a giant boulder that rolls from the top of the screen to the bottom, destroying all plants and zombies in its column and the column in front of it. The one with the flame releases green flames across the lane that burns all plants and zombies in its row, which is similar to Jalapeno. All levels featuring trap tiles have pre-given plants.
Usually, it is a smart idea to use these to your advantage; planting low-costing plants onto them and using the rolling rock to attack zombies can make quick work of them, notably being able to kill a Gargantuar in one hit. They are also capable of hitting airborne zombies such as Bug Zombies, making them a viable offence against them.
If there are no airborne zombies around, such as Bug Zombie, a player can get away with not planting on lanes with these, since a zombie will just burn itself and everything on its lane upon touching it.
However, if an airborne zombie is indeed involved, things can get dicey particularly quickly; setting up a temporary defense against the airborne zombie until it hits the flame time can work, but setting up an entire defense not utilizing the flame tile whatsoever can also be viable if a player is struggling to keep this defense strategy up.
- Every Trap Tiles level has at least two flame traps and two boulder traps.
- The boulder seems to be dropped from one place, bounces once then proceeds to roll towards the other side of the lawn. Also, the boulder's shadow is too small.
- Currently, it is unknown if floating plants such as Ghost Pepper and Rotobaga can activate the trap tiles, as all levels have pre-chosen plants, and none of them have them (though it is possible in the Chinese version).
- It shares the same circle shape (surrounding the boulder/fire symbol) as the Gold Tile. This suggests that they are related.
- In the Chinese version, if zombies are killed by the flame trap, they will die normally and lose their heads, instead of turning into ashes, while plants killed by the flame trap will simply disappear instead of burning.
