Modern gaming machines use computer technology to operate their functions. Slot machine outcomes are determined unsing a Random Number Generator (RNG) which is a mathematically-based program that selects groups of numbers to determine which symbols are selected to produce a winning or losing outcome.
The truth is, yes casinos can control a slot machine or rig it only to give players small wins. Some casinos work with developers to create exclusive games. This gives them even more access to a game's code and RNG.
Many fruit machines have a 'hold' button. This lets you pause certain reels during play, increasing the chances of winning. For example, if you had two lemons in a row, you could hit 'hold' and continue spinning the remaining reel in the hope of getting another lemon.
Divide all players into three groups of fruit by going around the circle and naming them either apple, orange or pear. The player who is 'in', calls the name of a fruit. If he calls out apples, everyone who is that fruit must get up quickly and change places. Players who are not apples remain seated.
It's widely accepted among players that the optimal times to play slots are early morning or evening, with peak hours typically occurring between 8 pm and 2 am. Take some time to watch the particular machine to gauge when it is most likely to pay out.
Typically, the more money you have to use to play, the higher the payout percentage is. For example, machines that requireR$1 or more generally pay out 95% to 99%, where 25 and 50 cent machines usually pay out 92% to 95%.
