Joker Jailbreak

A solo card puzzle played with a standard 52-card deck (jokers removed). The layout places a joker token in the center with four face-down wall stacks of six cards each on its sides and two face-down corner stacks on each diagonal; one card on each stack is turned face-up, creating eight surrounding open cards and a remainder pile. Players remove cards by pairing opposite colors of equal rank or by combining multiple cards of the same color to match a single opposing rank (A=1, J=11, Q=12, K=13). Revealed cards beneath removed cards are turned face-up and become available, and up to three cards from the remainder may be played onto the joker as temporary aids but must be cleared before a wall is empty. The objective is to clear all cards from any one wall; play ends in failure if no legal pairs remain. Difficulty adjusts by changing corner stack sizes.
