One way that you could increase the potential winning pay-outs that a slot machine could offer you, is by you activating few pay-lines than the maximum number of then that a slot has on offer.
However, you are only going to be able to activate fewer pay-lines when playing a slot machine if it has been designed as an optional pay-line slot, for there are quite a number of slots available these days that have fixed pay-lines or offer an All Ways or All Pays type of playing structure, on which players are forced to have to put into live play every single pay-line or every way to win a slot game offers.
So, if for example you come across a 10, 20, 30 or even 50 pay-line slots then by reducing the pay-lines you have in live play to 3 or 5 of them, but by wagering a higher coin denomination or by playing more coins on those pay-lines than you ever would when playing maximum line spins, there is always the chance of spinning in a high valued pay-out.
You should also be on the lookout when adopting this low pay-line slot playing strategy for slot machines that offer some form of bonus game, as when playing fewer lines but for higher stakes there is always the very real chance of a mega sized bonus game winning pay-out.
Pick and win bonus games do tend to be the ones that can award some huge valued winning pay-outs but pick out the slots which require three bonus symbols to line up on an activated pay-line to trigger those types of bonus games, rather than scatter symbols.
I say that as the chances of you triggering such a bonus game when you are playing fewer pay-lines, that are triggered by bonus symbols that need to line up on activated pay-lines will be much harder to trigger when playing fewer pay-lines, but when you do finally get one triggering there can be some large pay-outs achieved when you play off that bonus game.
