Kaiten - Sushi Deckbuilder is a single-player strategy deckbuilder for PC that blends card play with a conveyor-belt combo system in a cozy sushi restaurant setting. Players draw sushi cards, serve combinations to meet flavor targets, and build permanent upgrades while handling increasingly demanding customers across short roguelike runs.
Gameplay
The core loop centers on serving customers at the counter. Each customer specifies a flavor target. Players draw a hand of sushi cards and select up to three dishes to serve, calculating points multiplied by any active multipliers to reach the required flavor score before running out of serves. Served plates remain on the conveyor belt for the next two turns, where matching types provide boosts to new dishes of the same kind. Serving three identical types in one turn triggers an Omakase Set bonus for extra value.
Deck building happens between customers through the Fish Market. Tips earned from satisfied customers buy new sushi cards or Chef Upgrades that grant permanent passives such as the Aburi Torch, Golden Chopsticks, or a Longer Conveyor. Weak cards can be discarded and the stock rerolled to refine the deck toward preferred playstyles. The belt mechanic encourages chaining similar sushi types for escalating multipliers across multiple serves.
Regular customers favor specific sushi types, while boss customers introduce rule changes that alter serving conditions. The Picky Food Blogger avoids tuna, the Sushi Purist rejects rolls, the Speed Eater limits discard time, and the Grand Critic in round eight discounts combo value. These encounters require adapting the deck and serving strategy on the fly.
Game Modes
Standard runs consist of eight customers and typically last 20 to 30 minutes. Each run functions as a self-contained roguelike experience where deck choices and upgrades carry forward only within that attempt. Success against the Grand Critic unlocks Endless mode for continued play beyond the standard eight-customer structure.
Progression elements include a collection of 24 sushi cards and 14 Chef Upgrades that can be combined in different ways across runs. The game saves automatically between customers, allowing players to pause and resume without losing progress in the current run.
Controls and Presentation
Input supports mouse, keyboard, or controller for selecting cards, managing the hand, and confirming serves. The visual style features hand-drawn artwork with bouncy animations that highlight successful serves and score popups. These elements reinforce the satisfying feedback loop of building combos on the moving belt.
Is It Worth Playing?
Kaiten - Sushi Deckbuilder suits players who enjoy short, focused roguelike deckbuilding sessions with a strong emphasis on combo timing and light customer management. The conveyor-belt system creates a distinct rhythm compared with traditional card games, rewarding repeated plays of the same sushi types while the upgrade shop allows meaningful customization of each run. Those seeking quick strategy experiences with clear goals and escalating challenges will find the eight-customer structure accessible, and the unlockable Endless mode extends replay value for those who master the base loop. The game delivers a complete single-player package centered on its core mechanics without additional layers that might dilute the focused design.
