In the days of mechanical slot machines, manufacturers had to carefully balance a number of factors to get an acceptable payout percentage, including the number of winning symbols required for each spin, and the frequency of those symbols appearing on a pay line (which might be horizontal, vertical, diagonal or some other pattern). However, as microprocessors became more commonplace in the 1980s, it became possible for software to assign different probabilities to individual reel symbols. This allowed manufacturers to make the probability of losing symbols appearing disproportionately greater than their actual appearance on a physical reel, while making it appear that the winning symbols are occurring more frequently.
One of the worst things you can do while playing slots is keep pouring money into a game in the hope that ‘the next spin will be the one’. This is a sure way to burn through your bankroll quickly and leave you with nothing to show for your efforts. Because slots are luck-based, they have no rhyme or rhythm and are 100% random. In short, they are completely unforgiving. If you don’t have the means to quit, then by all means keep going – but be aware that every spin is a chance for a loss.
