    Enjoy 10 different puzzle game types:

    ◆16 Puzzle

    Rearrange 16 scrambled image pieces to complete the picture.

    ◆Spot the Difference

    Among 16 scrambled pieces, some contain pieces from different images. Identify and select the odd pieces by comparing with the sample shown in the top right.

    ◆Sorting

    Using left and right mouse clicks, determine whether each given piece belongs to the left or right image displayed on screen.

    ◆One-Stroke Drawing

    Move your cursor across a masked screen, avoid obstacles, and pass through every area exactly once without revisiting any spot to reveal the image.

    ◆Pop It

    Move your cursor across a masked screen while avoiding moving obstacles, then click all areas to reveal the image.

    ◆Thief Defense

    Use left/right movement and shots to repel obstacles trying to steal image pieces and protect them for a set duration.

    ◆Maze

    Navigate your cursor toward the goal in the bottom right corner.

    ◆Belt Puzzle

    Rearrange 16 scrambled pieces by moving 4 vertical and 4 horizontal pieces simultaneously to complete the image.

    ◆Rotation Puzzle

    Rearrange 16 scrambled pieces by rotating groups of 4 adjacent pieces in different directions to complete the image.

    ◆Tilt Maze

    Place missing puzzle pieces back into the holes in an incomplete image, but pieces can only be placed after clearing a maze.

    Editorial Review

    PuzzleCollection with 粟 occupies a deliberate niche within adult game design: the gamification of CG access. Rather than presenting illustrations as immediate rewards or narrative payoffs, this work treats them as puzzle prizes, appealing to players who enjoy both the friction of gameplay and the satisfaction of systematic unlocking.

    What distinguishes this collection is its deliberate puzzle variety. Ten distinct game types—ranging from traditional 16-piece rearrangement and spot-the-difference challenges to more kinetic tasks like one-stroke drawing and maze navigation—prevent the unlock mechanism from becoming monotonous grind. The Thief Defense mode, which layers action-game reflexes onto the CG-unlocking formula, is particularly clever; it recontextualizes the images as objects worth defending rather than mere rewards. This structural thoughtfulness elevates the work beyond basic CG galleries dressed up with token minigames. The Touhou Project IP anchor provides established character recognition and fan enthusiasm, which matters for audience retention in a work that asks players to complete ten different puzzle types.

    The appeal hinges entirely on whether you value the puzzle-as-gating mechanism itself. This isn’t a visual novel where gameplay and narrative reinforce each other; it’s a collection where gameplay *is* the content. The production quality’s adequacy matters less than the puzzle design’s engagement and the CG quality’s appeal—both invisible from the synopsis alone, making this a trust-the-artist purchase.

    Players seeking immediate visual gratification will find this approach needlessly obstructive. Players fatigued by traditional CG galleries and seeking mechanical engagement will find genuine value in the variety and thoughtful puzzle selection. This work knows its audience precisely and caters to them without compromise, which is exactly what a strong doujin design should do.
