The game has 13 letter dice that players roll up to three times, trying to form a crossword with them before a sand timer runs out. When a player is done or time runs out, they score the value of the words minus the value of unused dice. First one to reach an agreed score (usually 200 points) wins the game. A classic since the late '70s - early '80s, Rapigrama remains one of the most popular boardgames in Argentina, sold in every toy store and supermarket.
