Ancient Nubari tile game

A sort of tile-based game that was played by the Ancient Nubari of the Malatran Plateau, usually for the purpose of teaching their children.

Description
This game came in a box, measuring wide and  long. They were made of a hard form of ceramic that the Ancient Nubari had developed and used in place of metal. These boxes had a lid that was hinged from the inside, which was opened by simultaneously pressing down upon the top left corners and bottom right corners of their long side.

Within each box were twenty-four colored tiles, which were marked on both their sides with symbols that came in pairs. The goal of the game was to turn the tiles over so that each pair showed.

Background
Within the adventure this game appeared in it was described as a sort of rebus puzzle, particularly comparing it to the American tv gameshow Concentration.
