In both versions of slots, the game algorithms are identical. The differences can be only in access to various paid options. For example, when starting a demo version, the user cannot participate in the drawing of the accumulative jackpots. This option becomes available only when a gamer deposits a real money bet.
The difference between the demo game and the paid session lies in the change in users’ behaviour. Players often change their strategy of actions. It may give the impression that the free mode has some technical differences.
