Entrejuegos is a game made to promote a board game store in Santiago.
It's a 2 player game, in the vein of Blink were you try to play all your cards as fast as you can. However, there are two main differences:
Speed is important, but most important is observation, because if, at any time a player plays a card that make an "Entrejuegos" you can call it and stop the game. An "Entrejuegos" (translation: "between-games") is a set of three cards, the first one of a type, the second of a different type, and the third must be the same as the first. So, for example, the last three cards are a Wargame, a Party Game and again a Wargame, you can call it.
The second difference is that the game has some scoring: 4 points for being the first one to throw all your cards, and 1 point for each Entrejuegos set.
