Castle Cats - Idle Hero RPG

A free cat-collecting RPG with idle play

You play as the leader of a cat guild and build a team from a large roster of cat characters. The game is free to play, according to the listing. Its main pull is that the battles can run without you, so the game suits people who want to check in now and then rather than play in long sessions.

The listing names well-known cats such as Cole and Marmalade, Hosico, Monty, Nala and Waffles among the roster.

Summoning, evolving and equipping cat heroes

The roster holds more than 400 cat heroes. You summon new ones, evolve them, and unlock traits, skills and outfits for each. Outfits are cosmetic, so they change how a cat looks without being tied to its battle role.

Building a team means choosing which cats to summon and upgrade, since the team is what fights on your behalf during idle play.

Idle battles and real-time fights

Your cats fight on their own while you are away. When you return, you collect the rewards they earned and spend them on upgrades and new summons. If you want to act directly, you can step into a battle at any time and help your cats fight.

So one game covers both a hands-off routine and active combat, and you can switch between the two from one session to the next.

Customizing your guild leader

Your guild leader has its own appearance, and the game offers more than 200 items to dress it. The listing presents this as a way to make the leader look distinct from other players, alongside the cats in your team.

Seasonal cat-themed events

The game runs themed events on a regular basis. The listing names Superhero, Holiday, Summer and Winter as examples. Each event is a limited-time update that brings its own theme to the game.
