These eight new cards will be the bases for the eight foundations, each would be built up regardless of suit to kings in intervals each indicated by the marker cards, i.e. the foundation under the ace is built up by ones, the foundation under the deuce built up by twos, the foundation under the trey built up by threes, and so on.
The foundation system is based on a set of eight new cards that will be used to build up the foundations, with each level corresponding to a specific marker card value.  This means that the foundation under the ace will be built up using ones, the foundation under the deuce using twos, and so on.
