Support Features (Customizable)

• Manual Checking: Manually add red lines to numbers.
• Hint Arrows: Indicates rows/columns that can be completely filled based on the numbers alone.
• Auto-Fill X: Automatically places "X" marks in empty cells when a line's requirements are met.

About This Version

• This version is the same as the free software version and the Steam demo.
• It is based on a free title released over 10 years ago, now updated with modern support features.

Differences from the Full Version

• Contains roughly half the puzzles of the full version (though still over 1,500).
• There is a cooldown timer before the "HELP" function can be used.
• Save data from this version cannot be transferred to the Steam full version. (Note: The Steam demo version does support data transfer).

All puzzles are designed to be solvable without using "HELP." If you aren't in a hurry, this version offers plenty of gameplay on its own.

Regarding AI Usage

• Translation: All English text has been translated from Japanese using AI.
• Puzzle Design: Generative AI was used for approximately 10% of the initial concept sketches. It was used primarily for composition reference; no AI-generated images are used directly in the game.

2026/04/13 update

Fixed an issue where the resolution would revert to 1280x720 upon Windows startup or restart when playing in fullscreen mode.

Added a new "Auto-fill" support feature to quickly fill in confirmed lines.
