Deadlocks
As in ordinary Klondike, Hana Klo can produce patterns that cannot be cleared, known as deadlocks.
Specifically, the game cannot be cleared when all four cards of month n are in Rows, and all four cards of month n-1 are face-down cards underneath them.
When playing with physical cards, you can treat the game as successful once you determine that it is deadlocked.
When implementing a digital game, it is recommended to avoid deadlocks algorithmically, for example by reshuffling.
