Yes, slot machines absolutely use algorithms to determine their outcomes. Modern slot machines are controlled by computer programs called Random Number Generators （RNGs）. These RNG algorithms constantly generate random numbers, even when the machine is not being played. When you press the spin button, the RNG algorithm selects a number at that exact moment, which corresponds to a specific combination of symbols on the reels. This ensures that each spin is completely independent and random. 
The algorithms are designed and tested to be truly random and fair, meeting the regulations set by gaming authorities. The specific algorithm and its parameters, often called the \“payback percentage\“ or \“return to player\“ （RTP）, are set by the manufacturer and cannot be altered by the casino after certification. Therefore, while the outcome of each spin is random, the algorithm dictates the long-term statistical payout of the machine. |
