This puzzle associates, three by three, patterns not always adjoining, which move together.
These associations combine with each other.
Caution is required in the face of the obvious.
These combinations, despite, sometimes, all similarity, only find their place in one position that must be found.
The size of the parts and the size of the model, as shown on the previews, are not contractual, as they depend on the format of the screen used.
The dimensions of the model and therefore the parts are easily set, the best ratio being 50% for the surface of the model compared to that of the play area.
The play area unfolds in full screen.
