There is a strong argument that the “best” games to play are those with a low house edge, as these should cost you less money in the long run, but it’s ultimately down to the preferences of the individual. If you want to try and make your money lasts as long as possible, then the low house edge games probably are the most suitable. If you want to try and go for a big jackpot win however, the slots might be a better option. You could also argue that the best games are simply the ones that you enjoy the most.
