New variant
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.
Click a card to select it, then click a highlighted destination — or drag and drop.
Grampus is a compact foundation game with an unusual multi-step progression rule. Four pre-seeded foundations each build from a specific starting card, but the build interval alternates between steps — one card advances by one rank, the next by two ranks, and so on. Two reserve cells provide temporary parking. The game is a rapid foundation race where the alternating-step rule creates non-obvious sequencing requirements.
One 52-card deck. Four foundation piles are seeded with starting cards. Foundations build regardless of suit following an alternating progression: the sequence for each foundation alternates between one-step and two-step rank advances (implementation details vary). Two reserve cells hold single cards temporarily.
Stock deals one card at a time. Each card goes to a foundation (if it fits), a reserve cell, or the waste. Only the waste top card is available for play. Win when all 52 cards reach the foundations.
The alternating step rule means the sequence of ranks each foundation needs is not a simple ascending scale. Computing the full sequence for each foundation before play begins prevents the common mistake of playing a card “one rank above” the current foundation top when the actual next needed rank is two steps above.
The reserve cells become most valuable when the waste produces a card needed on a later step — parking it prevents losing it when the waste cycles, without committing it to a position that blocks a different foundation.
Two reserve cells are limited. Filling both with cards that have no clear near-term foundation path leaves no buffer for the next useful waste card. The best reserve use is a card whose specific step in the foundation sequence is known to be two or three deals away — close enough that the cell will not be occupied indefinitely.
