At snack shops and convenience stores around Portugal, you will often see a perplexing yellow and red box with punch holes near the cash register. We learned that it is in fact an awesome game-of-chance involving chocolate candy, called a “Caixa de Furos,” literally a “box of holes” in Portuguese. The boxes are branded by the chocolate brand Regina, so the surprise you receive will be chocolate. So what happens is you use a little pick to punch a hole in the white circle board and then a color-coded ball falls to the bottom of the box. Depending on the color of the ball, you get a different kind of chocolate candy from behind the counter. We tried our hand at a box and got a yellow ball, which got us a Regina chocolate umbrella, one of the most iconic Portuguese treats. You can even buy a small version for your home (which might by dangerous).
