Realistic physics
Pour, mix, knead
The slime is driven by a real-time material simulation: it flows, stretches, keeps a dent for a while and slowly settles back. Every touch answers with its own sound and haptic feel.
-
Pour
Choose a colour from the shelf and let the paint flow into the bowl. Tilt the phone to pour faster.
-
Mix
Drag your finger through it: the colours marble first, then blend into a single shade as you keep mixing.
-
Play
In the Play Area, stretch the slime with two fingers, squeeze it, poke it and fold it.
The aurora paint shown here is part of Yumuş Plus.
Blue and yellow make green.
Colours mix like real pigments rather than light on a screen: blue and yellow turn green, not grey. A spectral mixing model from paint science makes this possible.
The free version includes 27 colours, 4 textures (Glossy, Cloud, Butter, Clear) and 5 add-ins. Save a slime you love in a jar and share its recipe code so friends can make the same one.
Mini games
Eight calming toys
Each is built around a single object: few options, direct touch and sounds of its own.
-
Pop It
Square, heart, round and cloud shapes; four colour schemes, three sizes.
-
Stress Magnet
A pair of hematite magnets: flick them, shake them, toss them up; they buzz as they snap together.
-
Sand Tray
Draw patterns in the sand; a turning bar smooths the surface again.
-
Bubble Wrap
An endless roll in three sizes; every bubble pops in its own way.
-
Cutting Board
Slice soap bars and sponges with a knife; every slice tips over realistically.
-
Zen Garden
Rake lines into the sand, place stones and draw waves.
-
Breathing Balloon
Breathe in as the balloon grows and out as it shrinks; 4-7-8 and box breathing.
-
Water Ripples
Tap to let a drop fall and watch the rings spread and blend across the water.
