Ryuukyuu — About this game
Ryuukyuu turns poker hands into a placement puzzle. Choose a card from four piles and fit it into the board, looking for matching ranks, suits or runs across rows, columns and diagonals. A strong move supports more than one possible hand, so keep several lines alive rather than filling a convenient gap immediately. The wild card can rescue a difficult arrangement or strengthen a valuable line. Start with the single-player stages to learn the scoring target, then try a single-board score challenge or a match against an opponent.
