Summon Master – Rule the Ages with Slimes

Step into Summon Master, an idle RPG where you summon slimes from different eras, evolve them through time, and grow your power through endless battles.

Begin your journey in the earliest age with simple slimes. Upgrade your summoning altar, unlock stronger forms, discover new slime types, and progress through ancient worlds, medieval times, futuristic lands, space realms, and the mysterious Quantum Age.
