Hedging bets is by far the most successful betting strategy. This is where you're able to place multiple bets to cover all possible results and still make a profit regardless of the outcome of the game.
A Horn or craps-11 bet, as it is typically called, is a one-roll wager that on the next roll of the dice their sum will be 2, 3, 11 or 12. If they total anything different (4, 5, 6, 7, 8, 9 or 10), you lose. If 3 or 11 appears, you are paid 15:1.
