Kolam Flow is a pipe puzzle with one idea nobody else has: you can mix colours.
Drag from a coloured dot to its twin. Fill every single cell on the board, not just the ones between the dots. Then press Run, and the board comes alive: liquid pours from every source at once, races along the pipes you built, and each one plays a note as it lands. Your routing becomes a short piece of music, and no two solutions sound the same.
THE MIXER
Somewhere on the board is a ring with three arms. Two colours flow in, and the mixed colour flows out. Yellow and blue make green. Red and yellow make orange. That green endpoint has no green source anywhere on the board, so you have to make it. It is a proper logic puzzle, not just routing.
75 LEVELS, FIVE CHAPTERS
Every level is built to have exactly one answer, checked by a solver before it ever reaches you. Boards grow from 5x5 to 7x7, and the mixer arrives once you have the basics.
First lines: learn the drag
Room to move: bigger boards
The mixer: two colours in, one out
Wider: 7x7 with no help
Both at once: everything together
DRAWN, NOT PHOTOGRAPHED
Every line, dot and icon is drawn by the game itself. The look comes from kolam, the rice flour patterns drawn on doorsteps across south India: dots on a grid joined by one continuous flowing line. Two dark themes, Night and Earth. No neon.
