Looney Pyramids
Looney Pyramids are colored pyramids that are used in many published and user-created board games by Looney Labs and others, similar to how a deck of cards can be used to play a multitude of games.
They were originally part of the single game Icehouse created by John Cooper, and until 2011 they were generally called Icehouse pieces or Icehouse pyramids. The original game, Icehouse, is based on a fictional game Andrew Looney described in a story he wrote. The four original colors were red, yellow, green, and blue, but today, they come in many hues.
A "stash" contains 15 pyramids (5 sets of the 3 sizes) of one color. A small pyramid has one dot; medium, 2 dots; and large, 3 dots. They are sized such that they nest neatly: small inside medium inside large.
Other games that use these pyramids include:
