Timber offcuts donated by local builders are shaped and smoothed into blocks. Each pack typically includes oak, beech, birch, ash and pine blocks.

The idea of the game is to take it in turns to remove a block from within the stack and to place it on top of the tower without the tower falling over. Easy at first, but increasingly difficult as the game progresses.

When the game begins, the tower is 60cm tall.

The blocks come in a hessian sack for easy storage.
