54 wooden bricks, a cardboard stacking sleeve, and a storage pouch. Stacked tower: 2.5 in. x 2.5 in. x 9 in. (6.3 x 6.3 x 22.8 cm). Rules included.

Three games from one set of bricks: the traditional tower game, dominoes, and a matching game using the symbols printed on the bricks.

The cardboard sleeve is what makes the tower game possible away from a table. Building a 54-brick tower by hand takes ten minutes and a flat surface; the sleeve does it in one go, which means it gets played more than once.

A nine-inch tower is the camping size — stable enough on a picnic table, and it packs into a pouch rather than a box.

Wooden bricks, so they survive being dropped on gravel and being packed wet, neither of which a cardboard game set does.

Printed symbols turn the same bricks into dominoes and a matching game, which is the difference between one evening's entertainment and a week's.

Coghlan's does not publish a player count or full rules on their product page, so we have not invented either. What is listed above is the box contents exactly as Coghlan's gives them.
