With most of the blocks already complete, you are ready to make the base. Start by oversizing the base and playing a test game, if it is very easy to stack all the blocks, then the base is too big. We made a round base with a 3 3/4" (95mm) diameter, but the shape is not critical - it doesn't even have to be flat. Bring the size down in small increments until stacking all the blocks becomes challenging or make more blocks to accommodate the size of the base. We recommend that you make a few more blocks to ensure that it is virtually impossible to balance all the blocks on the base. This will make for a challenging solitaire game. A few extra blocks is also a good way to keep the game functional even if you lose a block or two.

The shapes are not critical, but we recommend that the base be relatively flat and the blocks are of similar size. The only critical component is the ratio of the base size to the size and number of the blocks. If the base is too big, then the game will not be challenging, if it is too small then you will only be able to fit a few blocks on it.
