Kakuro Blend

Kakuro Blend is a logic puzzle in which you fill empty grid squares with colors instead of numbers. Each square belongs to a horizontal and vertical clue: place colors so their mixtures match the colorful triangles beside the relevant rows and columns. The 40 puzzles grow in difficulty and range from 6×6 to 15×10.

Solve the color clues

The color selection area offers nine colors spaced evenly around the RGB color wheel, avoiding mixtures dominated by browns and greys. Some colors, particularly the greens, look almost alike but mix differently with other colors. Some resulting mixtures also look alike despite having different correct answers, so you need to use the clues and test how colors combine.

Each puzzle has a unique solution. Eight color palettes vary the available mixtures across the game, and the puzzles offer over 10 hours of gameplay.

Tools for tough puzzles

Four tools can help when a level gets difficult: an error button, a hint button, pencil mode and the color lab. In the color lab, you can mix any available colors and compare the result with a clue. Right-clicking a color places it beside your mixture in the lab for comparison.

Interface and progress

The interface is designed to be easy to understand, and progress saves automatically. You can play entirely with a mouse, with keyboard shortcuts available for most controls and buttons.
