Each spin, flip, or draw is completely independent. A roulette wheel has no memory. If red comes up 10 times in a row, the odds on the next spin are still exactly 50/50. The feeling that you're "due" a win is one of the most powerful illusions gambling creates — and the casinos built their entire business model around it.

When a slot machine shows two jackpot symbols and a third just misses, your brain reacts almost identically to an actual win. Dopamine fires. You feel excitement. But you lost. This is engineered — near-misses are deliberately programmed to keep you playing. It's not bad luck. It's design.

Unpredictable rewards are far more addictive than predictable ones. When you don't know if the next pull will pay out, your brain stays in a state of heightened anticipation. This is the same reason you keep checking your phone. Slot machines are literally optimised using the same psychology. The uncertainty is the product.

After a loss, the brain shifts into a state where recovering the money feels urgent — almost rational. "I just need to win it back." But chasing losses statistically leads to larger losses. The house edge doesn't change. What changes is your emotional state, which clouds judgement and increases risk-taking. Walking away is never a failure. It's the mathematically correct move.

Gambling triggers a sharp dopamine spike — the same chemical released by food, sex, and drugs. But repeated spikes cause the brain to downregulate, requiring more stimulus to feel the same high. This is why wins stop feeling satisfying. The chasing isn't about the money anymore — it's your brain trying to recapture a chemical state it can no longer reach. Recovery literally rebuilds those pathways over time.
