HEXAMIX - A Color Merge Puzzle

HEXAMIX - A Color Merge Puzzle

HEXAMIX is a strategic hexagon placement puzzle built around color mixing.

You are dealt primary colored hexagons — red, yellow and blue — one at a time, and you choose where to drop them on a hexagonal board. The moment a piece lands, it merges with every compatible neighbor at once, and the cell settles on the color that took part in the most merges. Secondary and tertiary colors are never handed to you: they can only be earned by mixing.

The reward grows exponentially with the size of the merge, so the game is a constant tension between playing it safe and setting up a big combo. Cross a score threshold and the board grows into a larger one, scattering whatever you left behind onto it — so today's mess becomes tomorrow's obstacle. Tertiary colors are dead ends that merge with nothing, slowly clogging the board. The game ends when there is nowhere left to place a piece.

Every so often a wildcard hexagon appears in the queue, pulsing and cycling through every hue. It blends with any color, and it is the only way to clear the dead-end tertiaries.

Features

• Star merge: a placed piece merges with all of its compatible neighbors simultaneously
• A 12-color RYB wheel — primaries mix into secondaries, secondaries into tertiary dead ends
• Exponential scoring: every extra merge doubles the reward, up to 64 points in a single move
• Eight progressively larger boards, from 7 cells up to 721
• Leftover pieces carry over into the next board, scattered to new positions
• A rainbow wildcard hexagon that blends with any color, including tertiary dead ends
• Built-in illustrated help pages explaining the merge rules
