When Bandit Keith activates "Gamble", and calls it wrong, you better hope to finish him off that turn, or stop his card with anything you have, because when the game tries to go to his turn, it skips it, which ends the duel, (which it shouldn't, as it should let you start another turn) resulting in a DRAW, no matter how badly you were beating him.

Normally this card has to be face-up on the field for 3 full turns for its double ATK/DEF effect to work, but if you use "Call of the Haunted" to revive it during your opponent's turn, on your turn following the opponent's, it's effect is applied, even though it's only the second turn.

On the main map, press R, then go to the Misc Menu. Select Password and enter these codes to unlock the corresponding card for your deck.
