Mahjong Daddy

Beautiful, colorful mahjong, created for true connoisseurs of this game.
There are no restrictions here: neither by time, nor by levels, nor by meaningless tasks.
Only the game itself, only mahjong!

A figure of knuckles is built on the playing field.
The task is to collect all pairs of identical bones.
They can be the same not only in design, but also in meaning.
For example, a summer tree and an autumn tree.
Tiles that have both long sides covered by other dominoes cannot be collected.
