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 calm, methodical puzzle game where you fill grids using logical deduction from cage sums, feeling like a satisfying mental workout.

What players say

Players appreciate the challenging puzzles and clean interface, but complain about missing basic features like background music, achievements, and a screenshot option after solving. The note-taking system is widely criticized as inconsistent, and some find the difficulty curve steep for newcomers. A few players also note that certain puzzles feel computer-generated rather than hand-crafted.
