The different Categories, Types and Themes in slot machines

Most of the slot machines we know today rely on the same basic principle to function. There are only few games with distinctive characteristics and basic structure. These games are often separated from the core category encapsulating slot machines when it comes to the classification of slots by categories. These sub categories, so to speak include games such the video pokers, and the Dices slots.

Dice slot machines are popular variants of slots, mostly played in western Europe, and specially at casino ( also offers Book of Ra, and several other Novoline Slots). Besides the two examples of direct variants, it’s important to know that there are many more alternatives or games derived from classic slots.

The most important differentiating characteristics in slot machines are:

  • The theme, and the storyline.
  • The number of Reels, rows, and paylines.
  • The maximum and minimum stakes
  • The Free Spins, Bonus rounds, Extra features and Gamble options (wild card, scatter, gamble options and more).

It is therefore possible to classify slot machines in recognizable categories and themes, according to the above criteria and standards. But, sometimes the difference between one category to the other might be as insignificant as a small variation in the graphics, design, or the storylines.

Slot machine Categories found among Novoline Slots

  • Classic Slots - fruit slotsClassic Slots: Mostly featuring 3 to 5 reels, and up to 10 paylines, classic slots are often represented in themes revolving around fruits. The idea of using fruits dates to the down of slot machines. Back in the day, similar themes such as flowers, sweets, gums, or food products have been tried out and developed, but none shared the massive success of classic slots with fruits symbols. The fruit machines are mostly characterized by a classic look and feel with a twist of contemporary graphics. As a rule of thumb, online casino software developers such as Novoline, Microgaming, Netent and others, tend to use the following fruits: Cherries, Apples, Grapes, Strawberries, lemons, and many others.


  • Adventure SlotsAdventure Slots: Also featuring 3 to 5 reels and an average of 10 paylines, the adventure slots category have some of the most popular and widely renowned titles. Probably, the most popular adventure slot machine would be the Book of Ra by Novoline.

But, franchise slots are set apart because of their presence and success in other areas such as movies, comic books, super heroes stories, Animes and so on. Franchise slots feature wild symbols, scatters, bonus rounds and free spins. The winning symbols are usually representative of the hero. Due to the enormous challenges and expectations to match the success of the slots’ counterparts in cinema or comic books, software developers put lots of efforts into creating games with amazing graphics and special effects to enhance the players’ experience.


  • 3D Slots (3-dimensional slot machines)3D Slots (3-dimensional slot machines): Due to the latest innovations and better rendering of products built with 3D technologies, many manufactures of slot machines entered the race build interactive slots.

This, without counting the many constants tied to offline casinos that players had to meticulously accommodate themselves to.

This is seen as a fantastic opportunity to test and discover the games without the pressure of risking funds, that can later be used to play the suitable real money slots after testing.
  4. No matter the casino chosen to play Novomatic slots, the games’ odds and payout rates will always be higher than those found in offline casinos. According to the RTP (Return to Player metric which represents the percentage of the total amount wagered in a machine, that will be redistributed to players) Novoline online slots have the highest payout rates in the casino industry with an average of 86% to 97% returned to players.
  5. Progressive slots in online casinos such as the Novoline Book of Ra Deluxe Jackpot Edition, Mega Moolah, Golden Sevens, or King’s treasure, offer an opportunity to win bigger jackpots than in land-based facilities. Due to their connected state (Progressive slot machines’ jackpots are linked in a network and every waged coin feeds the jackpot sum), the Jackpot grows much faster.
  6. A bigger game selection. The average online casino feature around 100 to 1000 slot machines in the game portfolio. The flexibility found online, allows providers to feature many different slot machines from various manufactures at the same time.
