Swipe the Flow

A new color guide tells you what the colors on screen mean, in words, and comes along in the photos and videos you save.

Move wind and liquid with your fingertips, then turn the motion into something of your own.

Swipe the Flow is an interactive fluid simulator that responds to touch in real time. No special knowledge or complicated controls are required—just swipe, draw, and watch flows and vortices come alive.

CREATOR UPDATE Add a photo, logo, or basic shape as an obstacle in Wind Tunnel. • Import photos and logos • Remove backgrounds on your device • Move, rotate, and resize each layer • Watch wind flow around your images • Save and share the result as a photo or video

FOUR WAYS TO FLOW

• Smoke Lab Follow the invisible air with smoke rising from chimneys. Drag the chimneys, spray smoke with your finger, and watch it split and curl around walls. Place a Smoke Sink to pull smoke in.

• Wind Tunnel Draw walls or place photos and logos, then watch the wind bend and flow around every obstacle in real time. Twelve colored structure presets and a Room preset are included, and Show air resistance draws an arrow and a number on each structure for how hard the wind pushes it. Show flow lines draws the paths the air takes, so you can see the flow split around what you drew and join again behind it.

• Liquid Art Create, push, merge, split, and stretch liquid drops. Tilt your device to shape them into living, shifting forms.

• Swipe the Flow Swipe freely across the screen to create colorful currents and spiraling patterns.

CHALLENGES

• Wind Paths Draw walls to guide the wind into the target. Fifteen stages in order: a narrow gate, a wind shadow, a 30/70 split, a vortex, a fast corner, reaching from afar, a vortex street.

• Wind Maze Carve a route through the solid block and get the wind out before the clock runs out. Around a boulder, spin a vortex, split three ways — and past stage ten, the maze arrives already sealed. You choose which wall to break, and rocks drop onto the path you opened, so you think again. Fifteen stages.

• Smoke Delivery Move the chimney and draw walls to send smoke where you want. Ten stages: dodge campfire smoke, keep the laundry clean, run a kitchen hood, open a window. The smoke is right there on screen, so you see what is happening at a glance.

Stages 1-5 are free in all three games; the rest (Wind Paths 6-15, Wind Maze 6-15, Smoke Delivery 6-10) are included in Pro. Compete with friends on Game Center leaderboards and achievements.
