What the Hex? comprises merely four two-sided hexagonal tiles. Players take turns moving a hex to another location, rotating and flipping it as they choose for the destination. Once there, the hex affects all the other hexes it touches. The player gets a point for each "diamond" of matched color of hex sides on any of the tiles.

Start with the two-sided tiles (the back is a functional mirror image of the front: It's as if the colors bleed through to the other side) in a diamond. On your turn, take a tile, then place it elsewhere, adjacent to one or more other tiles. Feel free to flip it and reorient it however you like before you place it.

First to twenty points wins, or if at the beginning of your turn, you're already three points ahead, you win.

You get points by matching colors. The arrows on the tile you moved tell you what happens to the newly surrounding hexes.

A straight arrow pointing clockwise or counterclockwise means that you should rotate the neighbor hex in that direction 60°.
The twisting arrow that's nestled between the straight arrows tells you to flip the neighbor hex, keeping the same color touching the new hex.
The flipping arrow that's unique to one hex tells you to flip the neighbor hex away (the equivalent of doing the above twist, then rotating 180°)
