How To Win At Popular Casino Slots

There is no method that guarantees a win at the most popular slots. Slots games play is random, which means the results are determined by a random number generator (RNG) software and there is no way of “guessing” them: Each spin is unique. However, we can still give some tips & tricks that will increase your winning odds.

Tip

  • Play popular slots online free as long as you can. The demo versions of popular slots have the same rules, features, and winning chance. Use them to practice and learn the game. More importantly, use them to find the games you really like. Both won’t cost you a penny.
  • Progressive jackpot slots are not that good. They pay big and they are probably the most popular slots, but progressive jackpot games have too low RTP values. In the long run, you will lose more. Prefer fixed jackpot games as long as possible.
  • Go for the spin number. By making more spins, you can get more chances to win. Each spin offers a new chance to score a payout. So, your goal should be getting as many spins as possible. To do that, prefer low-cost slot machines (i.e. penny slots) and play them with the minimum bet amount.

Famous Slots Need Famous Developers

So, who makes slot machines? You may think that the online casinos make them but that’s not true: There are software companies out there whose sole job is to develop these games. And, as can be expected, some of these companies are better than others. We list the best ones below – these are the companies that make the best slot machines with bonus games.

  • Microgaming Slots Analyze
  • Microgaming

    The developer of Mega Moolah and many other famous slots. Microgaming literally invented online slots by launching the first online casino in the world back in the 90s. It has a delivery platform named “Quick Fire” that hosts more than 600 games.

  • Red Tiger Gaming big logo
  • Red Tiger

    Founded in 2014, Red Tiger uses HTML5 to develop the best slot machines to play online. This means all of its games are compatible with mobile devices – no matter which platform it is; the games of Red Tiger will simply run. We recommend taking a look at Diamond Blitz, The Wild Hatter, and Golden Cryptex.

  • Nextgen gaming logo
  • Nextgen Gaming

    : If you like high limit slots, Nextgen will be your most popular developer. It is a part of SG Digital nowadays, another famous provider who develops good slot machines. Nextgen offers a variety of themes and lots of adaptations, such as King Kong Fury, Flame, and The Mask. Its “Foxin Wins” slots are one of the most popular casino slots series out there

Best Payment Methods To Play The Best Online Slots

You can find hundreds of free new slot machines online and play them as long as you like, without spending a penny. Take a look at our online slots guide or the best payout online slots UK, for more info: We explained this topic in detail. However, sooner or later, you will want to try your chances with real money – playing the best online slots free is good but playing with real money is a completely different experience. When that happens, you should use one of the payment casino methods we listed below for your deposits and withdrawals, we recommend our neteller casino list

Paypal big logo

PayPal

The most popular e-wallet service to pay for the most popular slots. A PayPal Casino is available literally everywhere, you can use it at almost all online casinos. Its payments are safe, secure, and nearly free of charge. PayPal should be your first choice to pay for the best online slots.
skrill big logo

Skrill

Skrill is a good alternative for playing popular slots games: It is almost as good as PayPal. In fact, it may be better than PayPal – Skrill supports more currencies and used in more countries. If PayPal is not available, Skrill should be your first choice to play slot.
Visa big logo

Visa

You can, of course, use your credit card to make deposits and withdrawals. And since VISA is the largest credit card provider in the world, we bet that you also have one in your wallet too. VISA is also a good option to play game slots – it is fast and practical. We recommend checking out our Best Visa Online Casino to learn more. However, you should still start with e-wallets, if possible: They are simply more secure.
Neteller big logo

Neteller

Lastly, we recommend using Neteller for the best slot machines to play online. Neteller is the “sister” of Skrill: Both brands belong to the same company. (In fact, even the Paysafe Card belongs to the same company.) If Skrill is available as a payment method, you can be sure that Neteller is available too.
