About FLOW
FLOW is a pipe puzzle on a glowing board. Drag from a dot to its twin to lay a pipe of that colour; pipes cannot cross, and the board is solved when every pair is joined and every cell is filled. One hundred and fifty levels from 5 by 5 to 9 by 9, each with a full solution built in. One drag per colour earns three stars.
How to play
Drag from a dot to its matching dot. Drag over a pipe to redraw it from there. Clear starts the board again.
FLOW runs in any modern browser on iPhone, Android, tablets and computers. Tap Play and you are in: no app store and no sign-up. Hold your phone upright and play with one thumb. Your best score goes on the worldwide leaderboard, and on a phone you can add the game to your home screen.
