Bonus games are a key element of modern slot machines. They add extra gameplay, increase player engagement and create the potential for big wins.
The bonus round is activated when certain conditions are met in the main game. Most often it is a drop of special characters, collecting certain combinations or achieving a game event.
During the bonus game, the mechanics may differ from the main one. The player can select items on the screen, receive additional spins, or launch individual game modes.
When developing bonus games, the mathematical model, RTP balance and general style of play are taken into account. The bonus should be rare enough to retain value but frequent enough to keep players interested.
JackCode develops various types of slot machine bonus games, including free spins, pick games, bonus wheels, and multi-level bonus mechanics.
