One of the predominant forms of games in online machines are bonus games. They consist of games on online machines that allow players to win and achieve bonus rounds in the game. However, one should distinguish these bonuses from the bonuses in casinos that are received through a paid deposit. Instead, the player gets a bonus in the machine itself. Players can get a bonus round in the game in several ways. Bonus games are generally obtained based on the symbols and various combinations that have appeared on the pay lines of the game.
