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.

What players say

Players call this a simple, skill-assisted riichi mahjong game focused on completing 58 achievements. The AI-drawn female opponents do not have adult content or reaction images. The game heavily stacks the starting hand and gives players skills to swap tiles, making big hands like four concealed triplets and thirteen orphans trivial, while luck-based yaku still challenge completionists.
