About this game

Slime Slapper combines an idle clicker RPG with a hands-on dungeon crawler. Collect your slime, build its strength, then take control as you explore rooms, dodge attacks and battle bosses.

Explore Greenwood and Crystal Caverns
Start in Slime Cave and progress through Abandoned Mine, Goblin Camp, Ancient Ruins and Greenwood Temple. Complete Greenwood Temple to unlock five Crystal Caverns dungeons, with crystal-lit chambers, new enemies and tougher bosses.

Take control in the dungeon
• Move through connected rooms and corridors.
• Dodge enemy attacks and use your slime's combat skills.
• Find seals and defeat bosses to clear each dungeon.
• Level up your equipped slime and prepare for the next challenge.
• Unlock new areas by completing the preceding dungeons.

Tap, upgrade and grow
• Improve manual slap power and automatic slime production.
• Activate constellation rings for temporary boosts.
• Unlock habitats and develop different upgrade paths.
• Return to rewards from idle progress while you were away.

Rebirth for permanent power
Choose from three rebirth paths and reset part of your progress to build lasting strength. Experiment with upgrades, refine your build and push your numbers higher each run.

Collect rare slime skins
Earn chests through play and reveal collectible Elemental, Mineral and other slime skins. Equip skins with different rarities, grades and traits, create loadouts, fuse extras and complete collections for rewards.

Quests and achievements
Complete daily and weekly quests, unlock achievements and climb the leaderboards as you grow your collection.

Play a few quick taps, focus on idle production or head into the dungeon for active combat. Slime Slapper brings collection, exploration and incremental RPG progression together on Android phones and tablets.
