One little slime. More power with every round. Soul of Slime is a strategic auto battler where card choices, elemental synergies and resource management shape every fight. Make your decisions between battles, then watch your slime put them into action.

SHAPE YOUR BUILD, CARD BY CARD

Buy cards from the shop, manage your gold and make every limited card slot count. Get stronger now or save for your next upgrade? Merge duplicate cards up to L3, unlock powerful abilities and assemble a build whose parts work together.

COMBINE SIX ELEMENTS

Granite, Mercury, Ember, Frost, Astral and Quintessence. Specialize in one element or mix several to create synergies. Your cards and their levels shape how your slime fights. Individual power matters, but so does the way your cards work together.

LET YOUR STRATEGY DO THE FIGHTING

Once battle begins, attacks and card abilities activate automatically. Watch the outcome, spot weaknesses and prepare for the next round. Asynchronous PvP, planned for release, will pit you against real players’ saved builds without requiring your opponent to be online at the same time.

SURVIVE 10 ROUNDS

Start each run with 3 lives. Every lost battle costs a life; your goal is to complete 10 rounds before they run out. Keep adapting through new cards, upgrades and changing matchups.

PUSH FURTHER IN ENDLESS

After successfully completing 10 rounds, continue into Endless mode in the full game. Keep your build, gold and remaining lives as battles grow tougher. Carry on upgrading: there is no fixed final round, and your run lasts until your lives run out. Then start again with a different combination.
