## What is Cube Flow?

Tap a block. Watch it break into cubes and ride the belt.

Cube Flow is a color-sorting puzzle built on a factory line. Stacked blocks wait on the feeders. Every tap sends one of them onto the conveyor, cube by cube, and the belt carries it toward the crates waiting at the top of the line. Match the color, fill the crate, ship it out. Clear every crate to finish the level.

HOW IT PLAYS

- Tap a feeder to release its front block onto the belt.
- Cubes ride the branch line, merge into the loop and roll past three crates.
- A crate only accepts its own color. Send the wrong one and it keeps circling.
- Crates fill as one solid growing block, then pop and slide away.
- Clear all crates to win.

THINK BEFORE YOU TAP

The belt only holds so much. Flood it with colors nothing is waiting for and the line stalls: no room to feed, nothing that can be delivered, level over. Every level is a small logistics problem. Which block goes first? Which color can wait a lap? Which feeder do you keep in reserve? There is no timer breathing down your neck, but there is always an order that works and plenty that do not.

FEATURES

- Simple one-tap control, no dragging, no fiddly aiming - tap anywhere on a feeder.
- Hand-built levels, each one a different belt layout to read.
- Blocks in every size, from thin slivers to wide slabs that eat half the line.
- Iced blocks that only thaw once you get a delivery through.
- Linked blocks that will not move unless both halves are ready at once.
- Deeply satisfying flow: cubes leap into the crate, merge and grow, and the finished block jumps off the line.
- Plays in portrait, one hand, anywhere. Gameplay works offline.
- Free to play, with ads.

Cozy enough for a queue, tight enough that you will restart a level to get the order right. Get the line moving.
