Not so.
All fruit machines have a 'logic chip' which assumes the way you will play, for example if you have 2 symbols in a row, with the third one in the next row up, it will often offer you a 'nudge'. It will assume you will use this nudge to bring the final symbol down. This is being processed by the 'logic chip'. But if you were to act 'illogically', the process is upset.
I don't wish to encourage anyone to gamble so I won't go in to any more detail other than my method relied on constantly confusing the logic chip, which paid great dividends
