Unlike land-based slot games, online video slots are completely digital and run on software. Whenever you spin the reels (columns) or place your bet there is nothing mechanical and the result will be completely random thanks to a random number generator (computer process used to generate an unpredictable series of numbers).
Some of you might be skeptical about this, but reputable software providers will all have their games monitored and regularly audited for gaming fairness by third-party authorities such as eCOGRA. Video slots are completely luck-based but some some have a higher return-to-player percentage than others (RTP).
Video slots have a minimum of 5 reels (columns) and 5 rows but this can go higher. With a larger grid size (columns and rows) video slots offer more paylines.
Paylines are important, as these are the lines you need to land matching symbols on. New game mechanics have allowed video slots to increase the number of ways-to-win, so that some slots even offer paylines in the thousands e.g Forgotten Island. There are also some that let you choose which paylines you want to be operational during a spin e.g Ancient Fortune Zeus.
As technology improves, software providers are constantly trying to offer something more exciting for players to enjoy. New features to video slots include cascading reels e.g Deadmau5, cluster pays e.g Ghost Glyph and even the megaways reel mechanic e.g Cash N Riches Megaways.
