Uses 1 pack of cards.
The Stock deals only one card at a time to the Wastepile, making the game easier.
But, the Stock cannot be restocked from the Wastepile.
A card on the Wastepile can be played to either the Tableau or Foundations.
A card on the Wastepile can be moved to an empty Tableau Stack.
Only 1 card at a time may be played to a Foundation Pile.
A random Base Card is automatically placed in the first Foundation Pile. The value of the card determines what cards can be placed on the other, empty Foundation Piles.

Build each Foundation Pile in ascending value from the Base Card, with all cards in a Pile sharing the same suit.

Aces can be placed on Kings if they share the same suit.

The game is won when each Foundation Pile contains 13 cards of the same suit.

The Demon pile uses one less card than Canfield.
The face-up card of the Demon pile can be played to either the Tableau or Foundations.
When a Tableau Stack is emptied, any face-up card on the Demon pile is automatically moved to the empty Tableau Stack.
If the Demon pile is empty, you may move a card from the Wastepile to an empty Tableau Stack.
Cards cannot be moved to the Demon pile.
The Tableau Stacks are used to manage and store cards, before they are eventually moved to the Foundations.
Only three Stacks are used, compared to Canfield's four.
Cards from a Stack cannot be moved to an empty Stack.
A single, front-most card in a Stack may be played to another (non-empty) Stack if it builds in descending value, regardless of suit.

Kings can be placed on Aces, regardless of suit.

An entire Stack may be played to another (non-empty) Stack, regardless of suit.

Partial Stack moves are not allowed. Either the entire Stack, or a single front-most card can be moved.
