All 52 cards are visible across ten columns in Xantia. Its tableau accepts neighboring ranks of the same suit in either direction, giving you more than descending runs to work with.
A suited chain can change direction
An exposed card can join the next higher or lower rank of its suit. A connected group can move together when each neighboring pair meets that same suited, one-rank rule; the chain need not descend throughout. Kings and aces do not connect. Any card or legal group fills an empty column.
Check the chain before carrying it
Four foundations build upward by suit from ace through king. Before joining a card to a chain, inspect whether you will need that card individually soon. A flexible tableau move can release a low rank, but a chain above it may still need separating. There is no stock or redeal.
