Key Metrics of Best Slot Sites
What makes online slot sites so popular? We look at some of the most important metrics for judging top-performing slot sites.
1. They Offer Great Casino Bonuses and Promotions
Bonuses and promotions are ways that online slot sites can stand out from the rest. The best slot sites offer bonuses for a variety of reasons. Some of these are:
- To attract novice players to their slot sites
- To attract seasoned bonus hunters to their online slot sites
- To push particular games
- To drive player activity during key parts of the year
- To build on player loyalty
New online slot sites might be extra generous with their promotions in order to build a player base. Established casinos will be looking to maintain their edge over competitor casinos in what is a highly competitive industry. There are many different kinds of bonus promotions:

Choose Your Casino!

With our spin-tracking tool, players can now take a data-driven approach to choosing a casino. Using our tool, you have access to statistics showing the overall performance of a casino, helping you to make smarter choices.
FAQ
Do some casinos pay out better than others?
Casino managers choose the slots they have running in their casino. Other than this, they have no control over the payout potential of their portfolio. The statistics shown on our tool are accurate representations of the performance of a casino’s games. This can be affected by whether the casino tends to favour high volatility slots or low volatility slots, or whether a big jackpot has dropped on one of the casino’s games.
How can I find the top 10 slot sites?
This question is entirely subjective. We encourage all players to look up casinos on our tool to check their statistics which are based on how previous players have fared at these casinos in the past. Remember that slots are inherently unpredictable. Once you’ve done all your research, you can wager your money at the casino.
Do games perform differently on different slot sites?
No. Games are not hosted on slot sites but are hosted on the supplier’s server and are therefore identical, irrespective of the casino where you are playing the game. There are – sometimes – different versions of the same game which casinos can choose to run on their casino, however this would be shown on the website page with the game’s stats being clearly listed.
