Playing with Pyramids is a collection of rules for 12 of the best games that can be played with the Icehouse pyramid pieces from Looney Labs. Several of these games were submitted by fans of Icehouse, designed for use with the pyramids. The games are mostly abstract, but the diversity of games included (analytical, inductive logic, dexterity, turn less, roll-and-move) means that most people will find something to interest them. Since this book's publication, many more games have been created and posted online. Most of the games will require five Treehouse sets, although for Volcano, you'll also need Volcano Caps.

The book contains rules to the following games:

• Gnostica
• Homeworlds
• Icehouse
• IceTowers
• Martian Backgammon
• Martian Chess
• Pikemen
• RAMbots
• Thin Ice
• Volcano
• Zagami
• Zendo
