Grampus Solitaire

Also known as Stalactites. Deal four foundation cards, arrange the remaining 48 cards into eight columns of six, and build every card onto a foundation regardless of suit. Choose to build in ones (A-2-3-…-K) or twos (A-3-5-…-Q). Use the two reserve cells to park cards temporarily — but once parked, a card must go straight to a foundation.

What is Grampus?

Grampus starts four foundations with random cards and deals the remaining 48 cards face-up into eight columns. Choose a single build method for all foundations: advance by one rank or advance by two ranks, wrapping through the deck. Two reserve cells hold one card each. Suit does not restrict foundation placement.

Full rules

One 52-card deck. Four foundation piles are seeded with starting cards. Foundations build regardless of suit, using the chosen one-rank or two-rank progression. The other 48 cards form eight face-up columns of six. Only a column top can move, either to a foundation or an empty reserve cell.

A card parked in reserve can move only to a foundation. There is no stock, waste, or tableau-to-tableau building. Win when all four foundations hold thirteen cards.

The chosen rank progression

In ones mode, Six needs Seven. In twos mode, Six needs Eight. The mode is selected for the whole deal; steps do not alternate from one card to the next. The board shows the next rank needed on each foundation.

A reserve move can reveal the next card in a column, but the parked card must eventually reach a foundation. Check its likely exit before using one of the two cells.

Reserve cell discipline

Filling both reserve cells with cards that have no clear foundation path leaves no space to move another blocking tableau top. Compare the cards beneath each candidate with the next ranks shown on the foundations.
