For the Pirate's of the Caribbean fans, you'll probably recognize this game. I was taught this game while I was stopped for the night on my recent cross country road trip of sorts. Liar Dice, or Liar's Dice or Perudo or Dudo or Call My Bluff or Mexacali (a drinking game equivalent) or doubting dice or etc is an easy game to pick up but you're likely to have a harder time learning much strategy as it's difficult to anticipate moves.
Step 1: What You'll Need
For this version of the game, you'll need:
5 Dice per player
1 Dice cup per player (anything to obscure your roll from your opponent(s))
You'll also need at least one other person to play with, but having at least three is recommended.
