Developer Yofukedo released the single-player title Ikasama Koi-Koi for PC via Steam on October 20, 2026. The game is currently priced at 1200 yen, though a launch promotion offers a 15 percent discount until October 29, bringing the cost down to 1020 yen.
Set in a nocturnal gambling den, the game blends traditional Koi-Koi Hanafuda rules with roguelite mechanics. Players must decide whether to declare victory with their current hand or continue playing to build higher-scoring combinations, risking a total loss if the opponent completes a set first.
The core gameplay involves outsmarting eccentric cheaters by utilizing special techniques and tools. Players can peek at face-down cards or swap hands, but must carefully time these maneuvers. If an opponent catches a player cheating, they face a monetary penalty and the temporary loss of that specific ability.
Progression involves choosing paths between opponents to reach the final boss, Ririka. Matches are decided by the total score across multiple rounds, with ties leading to extra play. Before starting, players select random skills, and victory rewards allow for acquiring new techniques, upgrading existing ones, or earning currency. Failure occurs if the player loses a match or runs out of funds.
