It will make you think of dominoes. Which is a good start.
There are 49 tiles. Wooden tiles. In a wooden box. Just as lovely as a lovely set of dominoes. Square tiles. Not like dominoes at all.
Each tile has a number in the center, ranging from 2 to 14. The number is surrounded on 4 sides by domino-like pips, ranging from 1 to 7. To play a tile, you must match the pip-count of all adjacent tiles. The value of the tile is determined by the number in the center. The score for a play is that number, multiplied by the number of matching adjacent tiles. So, of you play an 8, and it is adjacent to 2 other tiles, and both sides match, you get 16 points.
The possibility of getting a higher score by matching more than one adjacent tile makes the game especially suited to family play. The younger player can derive satisfaction from making a simple match. The older players can find significant challenge by trying to make the highest scoring play possible (matching all 4 sides).
The artful distribution and configuration of tiles invites mathematically-oriented players to get even more engaged. There’s only one tile worth 2 points, and all 4 sides have only one pip. There’s also only one tile worth 14 points, and all 4 of its sides have 7 pips. There are 7 tiles worth 8 points. These tiles have anywhere from 1 to 7 pips on their edges.
Just enough complexity so that those who want to take the game seriously can find serious things to think about. Just enough simplicity to invite some significant glee.
Yes, Quartile is made in China. And yes, again, it has been carefully examined for lead and other bad things and as been found most consumer-worthy.
