Juesos or Bones is another name for Dominos. I played a version of the game that I've not seen before. It dealt with multiplication by 5's. We were playing really late and we were tired, aka lazy, so we played by addition instead. In order to score, you first had to at least score 10 or more. To score, you count the numbers on the end of each tile that is on the end of the lines, then add the number of the tile that you were adding. You could only keep the number if you called it before playing it and if you had a number such as 5, 10, 15, 20, 25, 30, etc.
We played for about 2 hours and we found that was fun after we got the hang of it. There were 4 of us playing.
This could be a great game to teach multiplication or addition. It would also be a good game to introduce to get used to using numbers in another language.
