For my Space Pirates game I thought of having treasure in the form of crystals and maybe more than one type of crystal. I have come up with the following idea. Players would collect crystals which contain 3 important elements. One would be common, one less common and one rare. These crystals are triangular and can be pieced together to form a larger crystal of greater value. The larger crystals could be made up of two to six triangles. The more connection of the same colour the greater the added value of the crystal to be traded in for money – most money wins the game.
Below is the ideal ultimate red crystal. Each corner would have a value between 0 (no trace of the element and probably indicated by a white corner) and 3 with 3 being the highest concentration of that element in the given triangle crystal.
One triangle – no additional points
Two triangles – two points
