are all the slot machines rigged

Legitimate and licensed casinos do not rig their slot machines. Rigging slot machines to unfairly favor the house would violate gaming regulations and result in severe penalties, including fines, loss of license, and criminal charges.

Modern slot machines use random number generators (RNGs) to determine the outcome of each spin. These RNGs generate random sequences of numbers at a very high speed, ensuring that each spin is independent and unpredictable. The randomness of slot machine outcomes is rigorously tested and certified by regulatory agencies to ensure fairness and integrity in gaming operations.

While it's natural for players to experience winning and losing streaks when playing slot machines, these outcomes are the result of chance and randomness rather than manipulation or rigging by the casino. It's important to play at reputable casinos that are licensed and regulated by relevant gaming authorities to ensure a fair and safe gaming experience.
