The 3D catalog: game boxes on wooden shelves, with the cat sitting at the counter next to its greeting.

The catalog in 3D

The same catalog has a room you can walk around in. The cat behind the counter is the AI Catbot, and they pick real games from it when you tell them what you feel like playing. Nothing is for sale, here or in there. Go in from here and this game is already out on the counter, with more like it waiting on the shelf next to it.

How it feels

A chill, logic-based puzzle game that feels like a relaxing mental workout with endless variations.

What players say

Players say the game delivers basic Sudoku but is missing features expected even in free alternatives: no notes or pencil marks, no numpad, no undo, and no dark mode. Some report crashes, and one reviewer says puzzles are logically unsolvable. A few find the hard difficulty too easy. It is free.
