Polyhex Puzzle

A tiling puzzle using polyhexes.

Individual polyhexes fit easily wherever you place them - but these ones want to bring their friends along and will be more challenging to deal with! Can you group them in more than one ways?

Each tile comes in two versions, one plain and one featuring a geometric pattern. Plain tiles are 5mm high, while the pattern is 1mm high (starts at 5mm) and its lines are 1.2mm wide.

The frame also comes in two versions: one consisting of the outline only, and one with a 2mm high base.
