Drag & drop cards onto the tableau without restriction. Once dropped they cannot be moved.
When all 52 cards are on the tableau the game will auto-promote to the foundation. You only win if the auto-promote sequence completes.
The strategy in this game is to carefully control the order the cards go onto the foundation.
Both versions, 8 Columns & 7 Columns, are free-to-play. No in-app purchases.
