UNO!

When I do English conversation with kids, we often play card games. One favorite game is Uno; we play "the Japanese way", where you get to put down several cards in a row. For example, if the color is red and the number is 5, you can put down as many 5's as you have. You can also do this with any other card.

Here's one of my students who whittled down all of his cards until he had four left, all draw 4's. See his expression of glee? He won, because he went out with those four, and his poor brother had to draw sixteen cards.

That day the kids also learned Spanish; they had no idea that "Uno" meant "One".
