The SlotsMate Guide To Best Slots


User experience is an important factor when it comes to expressing one’s opinion regarding an online slot, and you can read below about some of the factors which real casino players keep in mind when rating any of the games on our website. So, what exactly makes a slot machine game a top-rated one?

  • Payout: This is, of course, a major reason for playing online slots. Even if you’re not playing for real money, on our page you can accurately see how a certain slot pays. Some pokies are more generous than others, so take this aspect into account when rating the slot you’re playing. You can check out this detail on the slot game page, but it may not be available for all slots, as we only use the information we get from the software providers themselves and not all of them are sharing this information.
  • Software: Since all slots are based on roughly the same concept, setting them apart is the responsibility of their designers. Providers such as NetEnt, RTG, Betsoft, and Microgaming have a diverse and rich portfolio, which showcases their unique take on the video slot concept. For this reason and more, you’ll encounter many of their titles in our Top Slots list.
  • Features Variety: There’s a wide variety of slots out there, from timeless classics to new, innovative arrivals which constantly showcase more and more flashy ways of increasing your winnings. Let’s take a look at some examples below:
    • Free Spins: These words are known by any slot enthusiast by now. They’re free rounds and represent real opportunities for considerable winnings. They have been making an appearance in most of the modern slot machines and has established itself as one of the most appreciated features among players. You can see for yourself how exciting free spins are in the Champions of Rome slot:

    •  Bonus Rounds: Variety is always welcome, even when we’re discussing slots features. Bonus rounds, which are fun alternatives to free spins, come in all shapes and sizes and, they too, offer potential free winnings. For example, in Blood Suckers II, you’ll be able to try your luck in a multi-level Hidden Treasure round, as you’ll see below:

If you want to read about these and more, such as scatters and progressives, check out their dedicated pages, where you’ll find a detailed explanation about each special element, as well as a list of slots featuring them.

  • Game Mechanics: Some pokies feature spinning reels, while others simply “drop” them on your screen, as you’ll see in the Gonzo’s Quest slot below. Autoplay and spin speed are other mechanics which considerably improve the player’s experience quality, but aren’t featured in all slots games. If you feel that a slot made it easier for you to have fun, don’t forget to give it a high score!

  • Graphics Quality: We know looks matter, for both classic and video slots, as they showcase the work that went into making them as enjoyable for the player as possible. While this may not seem like such an important detail, when you’re spending your free time with a video slot, you might as well find it visually pleasing. Check out Betsoft’s high-quality graphics trailer if you want to see how good can video slots look:

  • Compatibility: This point does not necessarily refer to mobile availability, as players also take into account the way a certain slot runs on more outdated devices. As slot machines evolve, they should be compatible with both old and new platforms, as not all players keep up with technological advances. Furthermore, given the fact that you can play most, if not all games without downloading them, they should not require too many resources to assure an enjoyable gambling experience.
