Mixwell

Part colour-mixing lab, part crossword grid: blend chips in a tray and place them so each row and column reads as a clean gradient between its endpoints.

How to play

Each row and column has fixed endpoint swatches. Mix a chip from the primaries in the tray, then place it in a cell so every line blends smoothly between its two ends.

• Add cyan, magenta, or yellow (plus a white base) to mix a chip — two primaries make a clean secondary.
• Over-mix beyond two components and the chip muddies and drifts off target.
• Click a cell to paint your chip; with an empty tray, click a placed cell to lift it back, or right-click to clear.
• Solve when every row and column blends cleanly within tolerance; faster and fewer placements score higher.

Controls

• Desktop: click primaries to mix, click cells to place, right-click a cell to lift a chip; choose size and Daily/Practice.
• Phone & tablet: tap to mix and place — touch-friendly (the right-click lift is a desktop convenience).

Game modes

• Daily and Practice seeds, plus 4x4, 5x5, and 6x6 board sizes.

Tips & strategy

• Keep chips to two primaries where you can; muddied chips rarely land within tolerance.
• Solve the endpoints' neighbours first — they pin down the rest of each blend.
