Our idle RPGs
We make two idle RPGs. They are new and still collecting ratings, so they are not in the table:

- Idle Summoner: Pixel RPG: summon up a chain of 55 pixel monsters, invade castles and rebirth. Pays you for up to 24 hours away.
How to choose an idle RPG
- Hero collectors (Castle Cats, Idle Heroes, AFK Journey) are about building a team; most earn from summons.
- Tap RPGs (Tap Titans 2) reward short active sessions.
- Roguelike idlers (Rogue with the Dead) change every run.
- If you play offline a lot, check the Offline tag in the table.
- If spending worries you, look at the top in-app price: Hero Tale stops at $8.99, most others at $99.99.
