Solitaire: Three Magic Towers

The game starts with eighteen cards dealt face-down on the tableau to form three face-down "pyramids" of six cards each, and a row of ten cards beneath. This is built by dealing out ten cards face-up in a row; then nine cards face-down above them, offset by half a card to the right; then six cards above those, offset by the same amount (and leaving a one-card gap after the second and fourth cards); then three cards to cap the three pyramids.

The twenty-four remaining cards make up the stock. The first card from the stock is put in the waste pile (sometimes known as the foundation/discard). For a card in the tableau to be moved to the waste pile, it must be a rank higher or lower regardless of suit. This card becomes the new top card and the process is repeated several times (e.g. 7-8-9-10-9-10-J-10-9-8, etc.) until the sequence stops. Along the way, any face-down cards that are no longer overlapping are turned up.

In case the sequence is stopped, i.e. no card on the tableau can be put over the top card of the waste pile, a card is placed on the waste pile from the stock to see if it can start a new sequence. Cards are transferred from the stock to the waste pile one at a time as long as it does not begin a new sequence with the cards on the tableau.

If there is no scoring being tracked, the game is won if all three peaks are cleared before or after the last card from the stock is discarded to the waste pile. However, the game is lost if there are still cards that cannot be placed on the waste pile after the stock has run out. When a scoring system is used, the game takes on different strategies depending on the rules. For example, in the original TriPeaks game, winning was less about clearing the peaks, and more about the tactics of making the best choices to create better winnings and limit losses by possibly quitting early.

TriPeaks can also be played with a wild card. This variation makes it easier to clear all three peaks. It is also possible to make all cards in the peaks face-up; this makes the game more thoughtful and strategic. It is also possible that the waste pile is empty so that one of the exposed cards can be chosen to go to the waste pile for a "head-start".
