Saidoku — Sudoku Flow

Saidoku ("color sudoku") is a logic puzzle where sudoku and color-making become one. Step into a traditional Japanese dye workshop. Solve the sudoku on the board, and colored water flows out of each tank by the amount of the number in its cell. Guide the water with sluice gates, rotating channels and holding vats into the dye pots, then fill the receiving jar with exactly the mix your customer ordered. Every color you finish, from madder red and golden yellow to indigo and young bamboo green, joins your swatch book of traditional Japanese colors. HOW TO PLAY - Tap a cell and a little craftsman walks over beside it. Pick a number and he smashes the stone slab with his hammer to reveal it. - The number in a tank cell is how much colored water that tank holds. The sudoku answer and the color recipe give each other clues. - Red + yellow = orange, yellow + blue = green, blue + red = purple. Add white for softer tones. Each color keeps its amount when mixed, and orders are judged by amount. - In ratio orders, work out each color's amount from the ratio and the total. - Release the water as many times as you like with no penalty.
