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.

A clean, minimalist logic puzzle that feels methodical and challenging, with a calm but demanding pace.

What players say

Players praise the challenging killer sudoku logic but are frustrated by a UI flaw where the number 1 note is hidden by the cage sum. There is no built-in note system, forcing players to rely on memory or external paper. The 100 puzzles across three difficulties provide long playtime, though some players note that puzzles sometimes lack a unique solution.
