Online Casino Slots and Games

We base our reviews on the following criteria:

  • First Impression
  • Gameplay
  • Mobile Version
  • Free Spins and Bonus Features
  • Progressive Jackpot
  • Biggest Win

First Impression

The first impression is, as so often, pivotal. If the game or more precisely the design, theme or gameplay spark our interest, we immediately decide to continue playing.

Certainly, the expectation of winning is a crucial factor to game evaluation. This refers to the assessment of the so-called volatility or in other terms our subjectively perceived chance of winning.

The introduction to a game is also part of the first impression. Especially, the first gaming experience is significant in terms of personal interest.


The quality criterion gameplay includes the visual and auditory design as well as content input. In short, the theme of the game and its presentation and design are key factors.

Regarding the theme, there are no limits to slot games. Slot machines let players immerse in a multitude of game worlds. Whether in mystical ancient Egypt, in the adventure filled wild west, in a magical underwater world or in colorful candy land – the range of slot themes is endless. Since there is a wide range of games for each theme, there is a vast selection of online slots to choose from.

Another essential element of gameplay is the design or visual presentation of the game. Consequently, color selection, graphics, number of pay lines, layout and visuals are part of the rating and heavily affect the game quality.

Sound and music selection are other important components of gameplay. The quality of the background tracks and game sounds, for instance when hitting a jackpot or winning free spins, is crucial.

Game handling and functionality are the most notable features of a good online casino game. Accordingly, the game structure needs to be self-explanatory, and the game flow needs to run smoothly to make the gaming experience enjoyable and entertaining. Additionally, build in features provide entertainment and variety. Features enhance standard games and turn them into interactive and full-fledged games.

Mobile Version

Since more customers access online casino websites on their mobile devices, the availability of mobile versions is essential. That is why, providers either offer an online casino app or an online mobile version that adapts to the respective mobile device and browser. Technical aspects, for instance load speed and response time, are heavily affecting the rating.

Free Spins and Bonus Features

As mentioned above, free spins and built-in bonus features make online slot machines exciting and versatile. The trigger for free spins, the nature of the bonus features, the combination possibilities and respective winnings differ according to the slots and reels.

Players can win predefined sums or prizes by hitting certain symbol combinations on the reels. Depending on the so-called pay line, players can directly assess the winning combination. The number of pay lines and combinations has increased during the modernization of traditional slots. Hitting a pay line may trigger animations, sounds, or storylines.

Moreover, players have the chance to win free spins or enter bonus games by hitting scatters or scatter symbols. Of course, not all scatters trigger free spins. Depending on the slot machine, it is also possible to unlock bonus games, for instance a selection of prize boxes.

Players have the option to freely customize online slots according to their personal gaming preferences. Depending on the slot, you can decide to either bet money on all pay lines or to choose them and the respective stakes individually.

The wild card is another unique feature. Wilds are particularly attractive for players as they substitute missing symbols to fill winning pay lines and thus winning combinations. Moreover, multiple wild cards can trigger additional jackpots.

Our GambleBoost Streamers are constantly checking out games and evaluating them in test runs that consists of one thousand consecutive spins. This allows you to take a first glimpse at the gameplay. You can find the test run videos on the individual game review pages. The runs show, of course, solely an excerpt. Nevertheless, this is enough to get a feel for the game and gather valuable information. Therefore, you should always consider watching our GambleBoost spin test videos before choosing a game.


Progressive Jackpot

The goal is, of course, to hit a jackpot. However, the sum of the respective jackpots can vary depending on the online casino game. In addition to traditional jackpots, there are also games that provide a so-called progressive jackpot. The sum of the ladder will increase with each bet made by the players. To make the jackpot sum rise faster, progressive jackpots include a selection of games. Furthermore, online casinos usually provide multiple jackpots that vary in size according to the previously played stakes.

Biggest Win

As stated above, every player wants to enjoy an exciting gaming experience and, ideally, win. Therefore, it is especially interesting to get information about the chance of winning and the potential winning sum. Community experience reports are certainly a helpful source in this regard. Not only the sum itself, but also the selected game and the played stakes are crucial details.
