How to play
Complete Czarina when every card reaches a legal foundation under its suit, base, direction, capacity and source restrictions. The engine checks the full card partition and terminal rule rather than a visual approximation.
- Czarina reconstructs its exact pile counts, concealed-card mask, seeded foundations and stock remainder from the route seed. The stock exposes 1 card per draw before any source-defined redeal transition. Restart reproduces the same deal locally without a network request.
- A move is accepted only when its source is exposed, its packet satisfies rank down wrap, and its destination satisfies rank down wrap plus the any vacancy gate. Invalid, stale, non-finite and post-terminal actions do not mutate state.

Strategy tips
- In Czarina, delay a locally tidy move when it blocks the only remaining stock or packet route. One random foundation card fixes a common wrapping base for four suits; five rank-descending wrapping columns force waste refills into vacancies and a draw-one stock has no redeal.
- The most common Czarina error is treating a wrapped rank edge as ordinary non-wrapping adjacency; the move may be legal in a neighbouring family while being rejected or strategically fatal in this exact profile.
- Before the final commitment in Czarina, count every live card, locked source and legal destination. Confirm that every card reaches a legal foundation under its suit, base, direction, capacity and source restrictions.
