Do you even play slots? (facepalm) There are three main features of Fruit machine slots:
i. Nudge: A nudge is nothing but a choice given to a player who is also popularly known as punter to perform a single step rotation of the reel chooses by the player. Nudges are never allowed by the machine for all the reels in a machine.
ii. Hold: The player could be provided with an opportunity to hold one or more reels before the spin. This means that except for the reel or reels selected by the player rest of the reels would spin.
iii. Cheats/Hacks: Cheats can also be made available on the internet or through emailed newsletters for subscribers. These cheats give the player the impression of an advantage, whereas in reality the payout percentage remains exactly the same.
