are slot machines predetermined

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, even when the machine is not being played. When you press the spin button or pull the lever, the slot machine's software uses the current random number to determine the result of your spin, including which symbols appear on the reels and whether you win or lose.

In this sense, the outcome of each spin is not predetermined in the sense that it is influenced by your actions or previous spins. Instead, it's determined by the specific moment when you initiate the spin and the random number generated at that moment.

However, some players may perceive certain patterns or sequences in the outcomes of slot machines, leading to the belief that the results are predetermined. In reality, each spin is independent and random, with no connection to previous or future spins.
