Don't let credits reach 0? Any truth in this?

[muchacho]

I read somewhere that you can 'confuse' fruit machines by doing things the FMC doesn't expect you to do -

For example, it gives you 2 cherries and an orange and gives you the option of holding - so you hold the orange and let it spin.

Whilst Im not sure if this is true, I then read not to let your credits reach 0 as this allows the FMC to reset itself. Instead, put another £1 in to prevent this from happening.

So guys, is there any truth to this at all?

Confusing the machine as you like to call it, can indeed work. I'd call it knockbacks.

e,g When you know its ready to pay on certain machines u can knockback certain boards/wins in order for it to overcompensate and give u a larger win. This was particularly useful a few years back but can still be adopted on some more recent machines such as monopoly's. Even some talk of not collecting wins on partytimes until they spin straight in...
