THE RULES
The goal
Every slot in the pipes waits for one colour. Fill them all and the stage is cleared. Put a ball in a slot that was waiting for another colour and the run ends there.
How a ball falls
Tap a ball in the reserve. It drops into the top of the pipe and falls to the lowest free slot. If that slot opens onto a branch that still has room, the ball carries on down the branch, and the same rule applies there.
A branch that is already full is blocked, so the ball stays in the main pipe and the stack keeps rising. Pipes fill from the bottom up, which is why the order you drop the colours in is the whole puzzle.
Reading a big stage
Tap any branch to zoom in on it. Drag to slide the board around, pinch to zoom, and press Zoom out to see the whole network again. The reserve never runs out, so take your time.
Stages and worlds
Stages are grouped into worlds of 15, each with its own look. The first three are a warm-up; after that every stage is generated, so they never run out and they keep getting wider and deeper. The stages page shows what you cleared and what comes next.
