Have you been playing online slots for a long time? Or have you just started? Is it your main hobby, or do you just check in from time to time when you have a moment and remember that you like to play?

In reality, it makes no difference how you play or how often; you still need to find the games that are going to suit you the best.

This is why it can be useful to do your research ahead of time, to ensure you already have a good idea of what to look for when you do have time to play when you deposit at 666Casino. Here are some of the best games to be starting out with. 

Who Wants To Be A Millionaire?

Who Wants To Be A Millionaire? is a game created by Big Time Gaming and, you’ve guessed it, it links back to the popular TV show of the same name. Part of the Megaways group, there are 117,649 possible winning combinations on this game, so add that to the already popular theme and you really do have it made.

To make things even better, there are free spins, extra (horizontal) reels, and even the help that you get in the show such as phone a friend and 50/50. There is a lot of potential here, but also a lot of volatility, so watch out if you decide to play this one; it could make or break you. 


When you play Cleopatra by IGT you’ll find a five reel, 20 payline video type slot that, with its ancient Egyptian theme, is a popular slot and one that has spawned many copycat games. However, this one is the original and, many would say, the best. You can earn 15 or more free spins throughout the game, and the jackpot is 10,000 credits. Even the RTP is respectable at 95.02%. 

This game was originally a real slot machine that you could find in casinos, and perhaps it is this that makes it such a good online game; the makers know just what to include to make this feel as good as the real thing, and that clearly makes a big difference. 

Book Of Dead

If you don’t want to have to think too much, or you’re just starting out, Book of Dead could be exactly what you need. Try Book of Dead slot for free on this webpage. This is a very simply game to play with the traditional five reels across three row, offering just 10 paylines. Although this may seem fairly unexciting when compared to other games, if you’re looking for something that offers you the perfect way to learn what slots are all about, this is the one for you. 

You can choose how many paylines you activate, of course, from one to 10, and the more you choose the more each spin will cost you, but the more you stand to win. You’ll have to work out for yourself what is going to be best; something a little more thrilling but potentially expensive or something that some would find boring but that allows you to play for longer.
