Slime Smash Guide: Mix, Rescue and Play Without Limits

Slime Smash is a free browser-based DIY slime simulator with no download. You stand at your own table in a long voxel slime studio, and your living Gloop may wish for a recipe, but that wish is only a bonus. The counter is always open, in any order and with no limits.

Start by holding to pour clear or white glue; the batch grows as much as you like. Add food colouring, glitter, foam balls, shaving foam, lotion, soft clay or glycerin. Then pour activator slowly: borax solution, contact lens solution with baking soda, or liquid starch. Stir between pours. The slime should move from runny to sticky to a glossy dome. Extra activator keeps working while the slime rests, so over-pouring makes it stiff and rubbery. If that happens, stir in a little water, lotion or glycerin to rescue it.

Once your slime is ready, play as long as you want. Tap bubbles for wet pops and combos up to x8, hold to squish, drag inside to swirl colours, or drag past the rim to stretch. Hold on grumpy Sour Bubbles instead of popping them, and fill the Satisfaction meter for a five-second Mega Squish with double points. There is no clock, so you can also invite friends, compete with bots or try the daily recipes at your own pace. For real-life slime, borax is for grown-ups: never taste slime and wash your hands after making it.
