Shuffle Tactics is a deckbuilding roguelike game that revitalizes established mechanics within the genre. Players navigate grid-based maps filled with enemies and objectives, using action points to deploy cards for attacking and defending. The game features three distinct characters with unique specialties: the Doberknight, an archer with ricocheting arrows, and a turret specialist, along with a magic user. Players can customize their combat decks by adding or removing cards after encounters and can acquire relics for passive effects and items to enhance specific cards. The game allows players to recruit sidekicks with their own decks. Each playthrough offers a unique experience, although some mechanics lack adequate explanation. The narrative involves a king who has gone mad, but it serves more as a minor distraction than a central focus.
