About this game

Connecting the colours is the easy part. Filling the whole board is the puzzle.

Every board has pairs of coloured dots. You drag from one dot to its match, without crossing any path, until EVERY tile is filled. That second rule is what changes everything: there is almost always a way to connect the colours, and it almost always leaves holes.

HOW IT PLAYS
Drag from one end to the other of the same colour. The line follows your finger tile by tile. Paths cannot cross or run over one another. Tapping a finished line restarts that colour, and undo steps back one move at a time. No move is ever irreversible.

FOUR MECHANICS, ONE AT A TIME
Obstacles that block the way and force you around. Bridges, where two paths cross without touching, one going straight across and the other straight down. Portals, linking two distant tiles: the line goes into one and comes out of the other. And connected edges, where the line leaves one side of the screen and returns from the opposite one.

Each debuts in a level of its own, with a short explanation, and only then starts mixing with the others. Nothing shows up unannounced.

400 LEVELS, EVERY ONE PROVEN SOLVABLE
From 4x4 up to 14x20, with as many as 10 colours on one board, in a single progression. An automatic solver checked each one before it shipped: no level reaches you without a proven solution. If you are stuck, the path is there.

Stars for time, points for speed, and a record per level. An optional Bomb mode, for anyone who wants the level against the clock.

ONE BOARD A DAY, THE SAME FOR EVERYONE
The Daily Challenge is identical for every player in the world, with a streak counter and a best streak. It gives you something to talk about and a reason to come back tomorrow.

BUILT TO ACTUALLY BE PLAYED
A colourblind mode, where each pair gets a shape on top of its colour. Statistics for levels, stars and time played. And the game picks up exactly where you left it, half-drawn line included.

OUR SIDE OF THE DEAL
No ads. None, nowhere: there is no video, no banner and no interstitial in here. No pay-to-win, because what we sell are themes, which only change how it looks, and hints. All 400 levels and the Daily Challenge are free from the first to the last, and you get a free hint every 15 minutes without paying anything. Play offline: nothing here needs a connection, your progress stays on your device, and the game collects no personal data.

All the art is generated by code, shapes, glow and animation, and the levels are created by algorithm. Not one pixel was drawn by hand.
