About Ubin Naga – A Free Mahjong Tile Slot Game

Where the idea came from

Many Chinese-Indonesian families have the same sound in their memories: the soft clatter of tiles being shuffled on a table after dinner. Grandparents, aunts and uncles take their seats, tea is poured, the children hover nearby to watch, and for a few hours the whole house seems to gather around one square table.

Ubin Naga ("dragon tiles") grew out of that warmth. We wanted a slot game that feels like a festival night in an old tea pavilion: red lacquer, gold leaf, lanterns overhead and ivory tiles carved with little pictures instead of writing. Our game, Naga Emas, turns that scene into symbols, from dots and bamboo tiles to plum blossom, lotus, gold ingot, phoenix and jade tiger tiles and the grand Red Dragon tile. Our blog has a longer story about mahjong tiles as a family pastime.

Meet the pavilion family

Cik Mei is the pavilion host who explains the rules. She greets every guest at the door and is happy to tell you exactly how every way, tumble and dragon wild works.
Engkong Ahok is the tile master with a hundred stories. He has played at the same table for decades, keeps his tea cup within reach and has a tale for every tile on the screen.
Ayung is Engkong's grandson, and he loves the dragon. When the golden dragon sweeps across the reels, he is the first to cheer.
Si Kim is a tiny golden dragon and our mascot. He is round, a little clumsy and very proud of the glowing pearl he carries everywhere.
