A rainy afternoon of board games is a great way to shred a family dynamic or discern who in your social circle has other issues in their lives that drive them to hound petty victories over their friends. Tip the balance with this guide to board-game cheating:

Scramble (Harsbo, 1948): In this game, billed to the scant demographic of literate children in the 1940s as “the crossword puzzle you build yourself,” you can easily secure victory by preemptively removing any dictionaries from your home and inventing long, complex words with vague definitions, such as quizlix: “a medical term, often used by highly intelligent Scramble players.”

Boatleshoot (Marshall Bradford, 1967): This guessing game of naval warfare is just like regular warfare—once you’re surrounded by it, there are no rules. Every time your opponent guesses a point on your grid that is a “hit,” reply instead “miss.” Your board is, after all, obscured from their view and in international waters, there is no honor system.

Chess (sixth century AD): If someone invites you to play chess, they have revealed three crucial weaknesses: they know how to play chess, they enjoy playing chess, and they have spent enough time practicing to have an expectation of victory. Cheat at chess by punching them in the face and taking anything they have that you yourself want.
