No, Hulk slots are not rigged. This is an urban legend and a myth perpetuated by those who lost a big sum of money. Slot machines cannot be set loose or tight. They are all programmed to be random. Every digital slot machine uses a random number generator, which is known in the industry as the RNG. The RNG is a software that guarantees each spin is independent of all the rest. It has no bias, and the slot will not know if the jackpot is already won or not. And because of this, there is no such thing as a hot slot, cold slot, or a rigged slot.
