+### [Checkers](https://en.wikipedia.org/wiki/Checkers)
+
+> Checkers, also known as American Draughts, an abstract strategy game where players move disc-shaped pieces across an 8 by 8 cross-hatched ("checker") board. Pieces only move diagonally, and only one space at a time. If a player can move one of his pieces so that it jumps over an adjacent piece of their opponent and into an empty space, that player captures the opponent's disc.

 ### [Lotería](https://boardgamegeek.com/boardgame/5878/loteria)
 
 > Lotería (Spanish word meaning "lottery") is a traditional game of chance, similar to bingo, but using images on a deck of cards instead of numbered ping pong balls. Every image has a name and an assigned number, but the number is usually ignored. Each player has at least one tabla, a board with a randomly created 4 x 4 grid of pictures with their corresponding name and number. Players choose a tabla (Spanish word for "board") to play with, from a variety of previously created tablas, each with a different selection of images.
