Connect the dots of matching colours and fill the whole board. Simple at first
glance - but the further you go, the less of it is luck.
HONEST PUZZLES
Every one of the 2540 levels has exactly one solution. Not one of many - the
only one: each board was checked by a solver that exhausted every alternative.
So a level cannot be stumbled through, only reasoned out.
LINES THAT MOVE
The line does not snap to the grid - it trails your finger, lags a little and
springs into place. A joined pair bursts into sparks, and a wave of light runs
along the finished line.
