How to make slime, then play with it: mix glue, colour and activator into a living slime with no limits, then poke, squish and stretch it in ASMR combos.
Slime Smash is a free online DIY slime simulator that shows you how to make slime, then lets you play with it, in your browser with no download. You stand at your table in a long voxel slime studio, with other slimers' tables side by side, and your Gloop, a living slime with a face, wishes for a recipe like fluffy pink butter slime or clear glitter slime. The wish is only a bonus: the whole counter is always there, with no limits and no fixed order. Hold to pour as much clear or white glue as you like and watch the batch grow, add food colouring that mixes like real pigment, glitter and foam balls that stay suspended inside, shaving foam for fluffy slime, lotion or soft clay for butter slime or glycerin for stretch, then pour the activator a little at a time: borax solution, contact lens solution with baking soda, or liquid starch. Stir and watch it change for real, from runny glue to sticky strings to a perfect glossy dome; too much activator makes it stiff and rubbery, and a little water, lotion or glycerin rescues it. A freestyle slime is always valid, named after what is really in it and graded honestly out of 100. Then comes the fidget play, for as long as you like. Tap the bubbles to pop them with a crisp, wet sound that climbs with your combo up to x8, hold to squish, drag inside to swirl the colours, or drag out past the rim to stretch a gooey strand that oozes back or snaps. Grab Golden Charms, 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: points raise your level, a new Gloop joins your Gloop Jar every few slimes, your recipe book keeps every slime, and a 1080×1080 card shares exactly what you made. Invite up to 14 friends to the tables next to yours with built-in voice chat, climb the live ranking and take the crown in the room challenge everyone gets, or compete with bot slimers on your own. Drag to look around in 3D, slide along the studio to anyone's table, or try the daily list of three recipes at your own pace. Works on desktop, mobile, tablet and gamepad.
