One concurrent player. Two reviews. A perfect 100% rating. The developer is literally called “100 Cozy Games, Cats.” Welcome to the marshmallow zone.

100 Marshmallow Cats launched May 10 on Steam at $1.79 — a 10% discount off its usual $1.99 — and it is exactly what it sounds like. Hand-drawn scenes. Hidden cats. You click them, they meow, they vanish, you get an achievement. Done.

This is not a joke. This is a franchise. The same developer has released 100 Korea Cats (1,093 reviews), 100 Funny Cats (1,656 reviews), 100 Radioactive Cats, 100 Ninja Cats, 100 Robo Cats, and roughly a dozen more. Every entry follows the same formula: tiny price, hand-drawn art, 100 cats, Steam achievements for each one found. Some are free. All of them work.

The appeal is almost pharmacological. As PC Gamer noted when recommending 100 Christmas Cats: “When you find a cat, you click on it, and it meows violently, pops out of existence, and you get a Steam achievement. It is incredibly enjoyable.”

The genre has grown large enough to attract genuine corporate warfare. Developer Nukearts Studio trademarked the phrase “Hidden Cats” in September 2025 and has since pressured competitors to drop the phrase from their titles. Reviews on Nukearts games have tanked in response. Nothing says “cozy gaming” like a trademark dispute over cat-finding.

But back to the marshmallow cats. The best review on the store page isn’t words — it’s a massive ASCII-art cat rendered in Unicode block characters, posted by someone who played for six minutes. That’s the whole review. That’s the whole community. Pure signal.

For $1.79 you get ten minutes of peace, a hundred achievements, and the certainty that somewhere a developer is already drawing the next batch.
