13 ORPHANS CLUB

We named our club after Thirteen Orphans, one of mahjong’s rarest, most difficult, and highest-scoring winning hands.

That is what our club represents: different people coming together around one table. Beginners, experienced players, friends, and strangers all connected through mahjong.

Based around Metro Manila and Quezon City, 13 Orphans brings people together for social Mahjong gatherings at different venues. Beginners and experienced players are welcome to learn, play, and connect around the table.

Mahjong has long been part of Filipino-Chinese (Chinoy) family gatherings and traditions in the Philippines. At 13 Orphans, we bring that familiar game into new spaces through beginner-friendly events and social gatherings open to everyone.
