## What is Pet Mahjong?

Pet Mahjong: Cat Dog Duo is real mahjong with three rule sets in one app: Hong Kong mahjong, American mahjong and Vietnamese mahjong. Take a seat at a cozy pixel-art table, play against cat and dog opponents, and enjoy a relaxed game at your own pace.

This is the game formerly called Cat Mahjong 3in1. The cats are still here, and now the dogs have joined the table.

Pet Mahjong is a one-time purchase: no ads, no in-app purchases and no subscription. Buy once, and every rule set, theme and avatar is part of the game.

Play fully offline: no internet connection needed.

THREE MAHJONG RULE SETS

Hong Kong mahjong
The Cantonese-style game many players know from family tables in Hong Kong. Draw, discard and build your hand toward a win. If you grew up around Hong Kong mahjong, this mode will feel like home.

American mahjong
Our American mahjong mode uses the studio's own American-style rules. American-style play is built around a card of hands, and in Pet Mahjong you can set up custom American mahjong cards and play toward the hands you choose.

Vietnamese mahjong
A Vietnamese mahjong rule set, right next to the other two styles. If it's the style your family plays, it's here.

Switch between Hong Kong, American and Vietnamese mahjong whenever you like. One app, three ways to play.

QUICK START FOR BEGINNERS
1. Choose your avatar and name. Pick a pixel-art cat or dog and type your name. You can change both anytime in Settings.
2. Pick a rule set. Not sure? Start with the style you've seen played at home.
3. Read the table. Each seat shows its points, and the center shows the round wind and how many tiles are left.
4. Draw and discard. On your turn, take a tile and let one go, keeping the tiles that bring your hand closer to a win.
5. Watch what your opponents throw away. Discards tell you a lot about the hands around the table.
6. Try the other styles once one feels comfortable.
