Abstract
The toy construction set includes a plurality of blocks and at least one base plate. Each of the blocks has one or more axially shiftable and rotatable coupling cams mounted therein which can be projected from the bottom of the block to effect vertical attachment with another block or with the base plate, using a suitable hand tool to do so. The preferred base plate contains a number of appropriately located coupling cams so that it can be attached either above or below a number of blocks.
