🎰 History of the Appearance and Development of Bonus Rounds in Slot Machines
Even at the dawn of the development of slot machines, when competition inexorably declared itself in the field of slot machine production, developers had to think about something more than increasing the number of reels and paylines. And this significant addition, which became a trump card in the rivalry of slot creators, was the bonus game. 🎲
The introduction of an electric drive into its device greatly contributed to the introduction of additional prize functions into the slot machine, since the capabilities of mechanics were still very limited. The first company to combine mechanics and electronics in the design of a slot machine was Bally Manufacturing. Thanks to a rather bold innovative solution for that time (we are talking about the mid-1960s), this slot machine manufacturer established itself as an undisputed leader for ten years and became practically a monopolist for this time.
Only in 1975 does the situation change, again thanks to the addition of a new element – the software RNG. The innovation belonged to a small commercial structure A1 Supply, which has long been absorbed by more famous brands and forgotten, but electronic algorithms, software modules, and other components of advanced computing machines created a solid foundation for the impetus of information technologies.
Then the appearance of microchips and software modules allowed increasing the number of variations of bonus games, and closer to the end of the 20th century, the rapid development of IT technologies, programming, and the emergence of the Internet took this feature to a new level. But classics with three reels remain a popular theme even in modern online slots, as does the bonus wheel.
In those years, when science fiction writers wrote and dreamers spoke about something only approximately similar to the Internet, even the risk game for doubling was taken for a bonus game. And this will not cause any surprise if we accept the fact that there was no special variety in the functionality of slot machines that exists now. Moreover, Gamble introduced an interactive component, causing the player to feel that the outcome of the game depends on which card they choose (black or red suit, first or fourth), even/odd, heads/tails, etc. In fact, this is not so. Such an opinion is false since the importance of the player’s choice in this case is an illusion, and everything is decided by mathematical algorithms based on RNG , in which a certain percentage of RTP is laid. Nevertheless, such a requirement for “feedback” remained at the peak of popularity for more than one year.
But in modern slots, bonus rounds really deserve attention.
✨ Bonus Game in Slots: Types and Winning Potential
Rounds declared as bonus ones are capable of significantly diluting the main game with interesting bright elements not only due to graphics but also solid cash winnings. Developers have created many diverse scenarios for such special game modes.

Popular types of bonus games in slots:
But these are not all varieties of bonus games found in slots. The imagination of developers is capable of creating other ideas that will be presented in the form of exciting bonus functionality of virtual gambling games.✨
🙌 How to Win a Bonus Round
The most popular conditions offered by gambling software developers are drops of scatters or bonus symbols in an amount of at least three pieces. Sometimes the requirement may be a collected collection of certain symbols. There are also more unique rules for launching a bonus game, capable of also arousing the interest of an online casino visitor and captivating them into the game process.

For example, on the Street Fighter II slot machine mentioned above, to go to the bonus round and fight bosses, you must initially defeat the first opponent in the main game. A blow that takes away energy is made when a productive combination of symbols with the image of the selected character falls out.
🆓 Bonus Game and Free Spins
It cannot be considered erroneous if someone calls a round with free spins a bonus game, because during such prize spins, special functions are often added to compose productive combinations, expanding the boundaries of winning potential and increasing chances of hitting a huge “win”. Nevertheless, free spins have begun to be attributed to a separate feature of a slot machine and now their absence sometimes even looks strange, and the slot – somehow unfinished or even flawed, and playing such a slot machine creates the impression that something is missing. Unless, of course, the absence of a round with free spins is compensated by the developer with an interesting variation of the bonus game. By the way, the same “Hold and Win” bonus game contains, albeit not typical, but still free spins and even re-spins. 😎
🌟 Well, when both free spins and bonus rounds with interactive elements are included in the slot functionality, such gambling games often become popular among regulars of internet gambling clubs. After all, playing a slot machine with a mass of bonus scenarios is much more exciting than one where mechanics only allow making spins, and for variety only a doubling game is provided. This is more to the liking of old-school players or strategists hatching their specific tactics.
💰 How Much You Can Win in a Bonus Game
Most often, it is in the bonus game that winning a jackpot is provided. For example, this is a bonus wheel or the Hold and Win function with a draw of several main prizes. Therefore, choosing a slot online by characteristics, you should take into account that the prescribed max win is prepared exactly in the bonus round. But most accurately, of course, it is written in the electronic documentation for the slot itself or will light up when loading a virtual slot machine.
It should be noted that now a winning potential of 50,000 and 100,000 bets is becoming the norm . But in a bonus game, a progressive jackpot can also be the main prize, and such amounts reach an order of magnitude larger values.
👉 Which Slot with a Bonus Game to Choose
If you want more variety, it is better to choose a slot where there is a bonus game, free spins, and, for a complete set, also a doubling game. But the last mentioned function is starting to lose its popularity.
Often a whole set of small bonus rounds are found in slots with cluster pays. Many games from top providers like Play’n GO or NetEnt are saturated with interesting functionality and additional prize rounds.
It is convenient to select slots according to certain criteria using a filter.

But the main thing is not to get carried away, keep yourself under control and play only for money that you can afford to lose. And if there is no desire to bet real money, then a huge collection of slot machines with bonus games for free is collected in this section! 🕺
