Slot machines appeared as a form of entertainment at the end of the 19th century. Initially, these were mechanical slot machines. The drums were set in motion by pressing a lever. Gaming sessions on such devices did not last long, because they required physical effort.
Types of video slots
The abandonment of physical reels allowed developers to implement different ideas when creating online video slot machines. Slots can differ externally and functionally, while maintaining the main game principle – the formation of combinations.
The list of slot machines on online platforms includes:
- three reel slots;
- five-reel slot machines;
- devices in which six or seven drums are involved;
- nine reel slots.
The number of prize lines also differs. Their number ranges from 1 to 100. There are also machines where lines are replaced by ways of forming combinations.
Among other things, slots differ in bonuses. Some slot machines offer a classic set of additional features: free spins, risk game, bonus round. Others expand the range of options with respins, prize features on the main screen and progressive jackpots.
How to play video slots
Playing video slots is easy. Even a beginner who has never played before will master the rules. All that is required for a gaming session is:
- set a bid;
- set the number of pay lines;
- select the game mode: automatic or by pressing the spin start button;
- collect combinations.
On most slots, combinations are formed from the same symbols, located sequentially from the leftmost reel to the right. Some combinations of symbols activate prize options:
- replacement of missing pictures in the sequence;
- launching free spins or respins;
- opening the built-in mini-game.
