About Purr-imeter Defense
Purr-imeter Defense is a free online cat tower defense game. You have a lawn. You have cats. Things that are not cats are coming across the lawn. Place your cats on grass tiles, upgrade them, and hold the purr-imeter for as many waves as you can.
Each cat type has its own stats — damage, range, fire rate — and some cats don't attack at all but buff every cat around them. Biomes change as you progress, enemies get tankier, and your economy never quite keeps up. It's a proper tower defense game with cat-shaped towers, playable instantly in any browser.
How to Play Purr-imeter Defense
- Tap or click a grass tile to select it, then pick a cat from the shop to place it there.
- Enemies follow the path across the lawn. Cats attack anything in range automatically.
- Tap or click an existing cat to see its stats, upgrade it, or sell it back.
- Support cats buff nearby cats' damage and fire rate — stack them behind your front line.
- Survive the wave to earn currency. Spend it before the next wave hits.
Tips & Tricks
- Corners of the path are where enemies spend the most time in range — put your best cats there.
- One upgraded cat usually beats two fresh ones.
- Don't leave money sitting around between waves. Money doesn't earn interest. It's a lawn.
