## Description

Mahjong Demon is a Chrome extension that simulates traditional Japanese Mahjong. Use the on-screen slider to select tiles, then tap to draw, discard, and form four Melds and one Pair, following Japanese mahjong rules including Melds, Reach, and restrictions on Chi, Pon, and Open Kan.

It also covers key concepts like Lost Hand and how Reach affects gameplay. The page explains scoring interactions, such as paying 1,000 points to Reach and the rule that Ron cannot be completed with a tile from another player's discard; self-draw remains possible with Lost Hand. Practical tips help you reason about hands from opponents' discards and plan winning strategies.

## Review summary

Mahjong Demon is praised for its portrait layout readability, fast AI, and clear scoring with Riichi support. Common drawbacks are the lack of landscape mode, visual clarity issues with tile graphics, and robotic voices. A solid pick for Riichi players who prioritize quick games and rule variety, but UI/audio and orientation concerns are consistently noted.

### Pros

- Portrait orientation provides easy legibility and convenience.
- Fast, responsive AI opponents with instant gameplay and practice against CPU.
- Clear scoring and rules explanations; beginner-friendly yet challenging.
- Riichi/Japanese Mahjong support with many rule options.

### Cons

- Lack of landscape mode; vertical-only UI makes tile pressing difficult for some players.
- Tile graphics are small and visuals can be unclear due to a busier 3D UI and color similarity.
- Robot/annoying voices; audio quality could be improved.
