Playing the tableau
The first foundation accepts any card of its own suit. Each lower foundation begins with the same rank as the first base and may accept a rank only after that rank appears immediately above it. Only reserve and waste tops may move.
Goal and first plan
Build all four suit foundations. The waste may be redealt after foundation progress has been made.
Read the base rank and suit first. That rank is the key that opens the other three foundations; look for it among the reserve tops before cycling the stock.
