Our take on Sin Castle

Each opened grid can present a different combination of monsters, stores, linked spaces, and hidden spaces, making grid contents central to the puzzle structure.

What is Sin Castle?

Sin Castle is a puzzle-focused adventure game built around opening grids and overcoming their contents.

Progress depends on assigning attributes, using items, and combining equipment under strict rules. More than 20 puzzle designs use these decisions in different ways, while grids can contain monsters, stores, linked spaces, or hidden spaces. The game includes more than 40 ordinary items, more than 30 special items, over 10 rare items, and nine four-piece equipment sets with set bonuses. More than 40 monsters across three levels call for different approaches. Its visual style draws on ukiyo-e and glass painting.
