Pyramology

There are 70 pyramids, all unique, using four colours which have a numeric value. All you have to do is match the colours of the pyramids to score the corresponding points. As the game progresses it gets more difficult, first matching just one face of a pyramid, then two, three, and finally four faces by placing pyramids into the 3 x 3 base and stacking the pyramids vertically. —description from the publisher
