Tile Denial

Difficulty: Medium

Tile Denial is an achievement in Plants vs. Zombies 2: It's About Time which requires the player to complete a Far Future level without planting on any Power Tiles. It is worth 500 XP on Android devices.

Strategies
Far Future - Day 8 is a perfect level to obtain this achievement. In it, you can plant the Power Tiles on the plants, rather than planting the plants on the Power Tiles. Beware though, as that level has Gargantuar Primes, meaning the level will be harder. Day 16 would be easier, as it is a Special Delivery level, although with the same intent as Day 8. Or you can go to Day 1 (after you beat it, or else, there will be two Peashooters on the Power Tiles) and win without planting on Power Tiles because the zombies are easy to defeat.

Trivia

 * This is currently the only achievement in Plants vs. Zombies 2: It's About Time that does not let the player plant any plant on the tiles.
 * The player can still get this achievement by not feeding Plant Food on any plant on any Power Tile.
