thumb on the scale
A method of deception or manipulation that creates an unfair advantage for the swindler, likened to a merchant holding a thumb on the scale when weighing goods for sale, therefore increasing the weight and price. You have to suspect that the casinos have their thumb on the scale when it comes to the slot machines. There's no way you're getting fair odds.
