I don't have much experience with slot gaming, but are there slot games that actually require some strategic understanding or is it all pure luck and it doesn't even matter which button you push?
Obviously you need to understand how the slot works first before you can play it. Ussually on slot games, you have 2 choice, 1 is bet with 1 bet (you set how much your bet and how many lines, then it will multiply your bet, i.e bet 1mbtc on 3 lines, so it would cost you 3mbtc for each time you bet) and the second is buy the bonus feature, when you buy that, you will have 5-10 free roll, depends from what slot game you playing. Usually you can hit huge jackpot on here, but you can get less than you paid too from bonus feature if you didn't hit any jackpot or huge multipler.
There is no strategy works in any kind of gambling games
