Derpy Cat — EchosOfMe LLC
Derpy Cat is a casual drop & merge cat game for iOS. Drop cats into the container, match same-tier cats to merge them into bigger, derpier cats, and try to survive as long as possible!
How do I play?
Drag to aim and release to drop a cat. When two cats of the same tier touch, they merge into the next tier. The game ends when cats stack above the danger line.
What is the Daily Challenge?
A new challenge every day with a fixed drop sequence. Everyone gets the same cats in the same order. Complete it to build your streak!
How does the streak work?
Play the Daily Challenge each day to build your streak. You get a 1-day grace period — miss one day and your streak survives, but miss two and it resets.
What is Catpedia?
Your collection of discovered cats. Drop or merge a cat tier for the first time to add it to your Catpedia. Can you discover all 10?
Can I continue after a game over?
In Classic Mode, you can watch a short ad to continue playing. Half of your cats will be removed, giving you another chance. This can be used once per game.
How do I turn off ads?
Go to Settings (gear icon on the main menu) and toggle "Show Ads" off.
How do I reset my data?
Uninstalling and reinstalling the app will reset all scores, streaks, and collection progress. All data is stored locally on your device.
