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 praise Agari as a straightforward, no-frills riichi mahjong client focused purely on the game. It is valued for offline and friend-only online play, with a clean interface and responsive developer who adds requested features quickly. The AI is competent for intermediate play, though some note the lack of random matchmaking and minor polish issues like small font and missing sound effects.
