Reels, paylines and RNG — three core concepts
At the heart of every slot game are the reels (vertical columns that spin), paylines (the lines along which matching symbols produce a win) and an RNG or Random Number Generator (a software algorithm that continuously determines the outcome of each spin at random). The result of one spin has no effect on the next — every spin is entirely independent.
RTP or Return to Player is the percentage a game theoretically returns over the long run. For example, Fortune Mouse has a maximum RTP of 96.96%. This is not a guaranteed return — it is an average figure calculated over millions of spins.
