You can find many different versions of the slot machines, both in the real casino and on the online casino, but they are just different in form, maybe different backgrounds or symbols, but the fundamentals are the same. Some of the following versions may be more interesting:
In a multiple game, the more coins you put in (usually up to 5, but also more), the more you win. Each coin is doubly paid, so if you set a 10:1, you can win 50 if you cast 5 coins.
In a traditional slot machine, you can win only if the three symbols in the middle wireframe match (or you don't need three symbols, but you must have a special symbol). Although you can see three wireframe boxes in most consoles, the top and bottom wireframe will not return any results. In a multi-line slot machine, you can add extra coins to activate these lines. Some consoles can enter up to 9 coins, or even more, requiring, for example, 5 matching symbols in three lines and diagonally aligned numbers to win.
Jackpot games in reality and online there are some of the most popular types, the cumulative jackpot game is one of them, it requires a certain proportion of the bet as part of the cumulative award pool, the jackpot is huge, but difficult to win. Any player who plays the jackpot will have to put a certain amount of money into the jackpot to make the final award, and once in, the winnings may be as high as $1 million or more. In this game, each rotation must be put into the largest number of coins in order to qualify to win the jackpot.
