Shamrocks

Shamrocks deals eighteen tiny fans of three and then imposes the rule that makes it hard: no pile may ever hold more than three cards. Building runs up or down and ignores suit entirely, which sounds generous until you realise most piles are already at their ceiling.

The result is a game with a lot of visible options and very few real ones, and wins are genuinely rare. It is worth knowing that a deal with a King sitting on top of a pile is usually finished before you start — recognising that early is most of the skill on offer, since there is no redeal to rescue you.

Eighteen small piles — seventeen fans of three plus one lone card — and a strict cap of three cards per pile, so you cannot consolidate your way out of trouble. Piles build either up or down in sequence with suit ignored, which is unusually flexible, but the three-card ceiling means every placement fills space you may need. Foundations build up in suit from the Aces. Only the top card of each pile plays, an emptied pile stays empty, and there is no redeal at all.

The three-card cap is the whole game and it works against you constantly: a pile at three is closed, so the flexible up-or-down building rule is much less useful than it looks. Count how many piles are already full before planning anything. The critical structural fact is Kings — a King buried at the top of a pile smothers everything below it permanently, and the reference is blunt that a deal without Kings at the bottoms of piles will not be won. Check that first and abandon hopeless deals early rather than grinding them.
