Random Number Generators (RNGs)
RNG’s are the algorithms used to pick a completely random sequence of numbers whenever you take a spin in a slot game, which translates to the totally randomized alignment of reels. In this way, online slots are balanced to be fair and unbiased.
Crucially, RNGs generate a new number every single pull, with no relation to the previously generated number. This is why streaks of good or bad luck are just that, with no possibility of being “due” for a change in outcome. RNGs are entirely objective and are inspected by regulatory and review bodies to ensure they stay that way.
Reels, Paylines, and Symbols
Each reel in a slot machine is decorated by symbols that determine your payout when they align in a payline. A payline is one pattern that needs to be filled with matching symbols to trigger a win, often in a straight or zig-zag line. Some special symbols include Wilds (which count as whatever symbol you require to complete a payline) and Scatters (which only need a certain number of matching symbols present across all reels to win, not necessarily in a payline).
Other fun features like free spins or multipliers let you play extra rounds for free or increase the size of your winnings, respectively. All these features help different real money slots stand out from one another and can cater to different playstyles.
Volatility
Sometimes called “variance,” volatility describes how reliably a slot machine pays out big or small wins. Slots that favour small, consistent wins with minor losses are low volatility, best if you’re a low-risk gamblers playing on a budget. Slots that favour huge wins and huge losses in equal parts are high volatility, promising heart-pounding gameplay for thrill seekers.
Volatility doesn’t necessarily affect the overall payout rate of a game—the term refers to the risk-reward proposition of a particular slot machine. Find the right volatility for you to enjoy games with a level of risk you find enjoyable.
Real Money vs Demo Mode
Most of the top online casinos in Canada will let you play online slots in “demo mode,” where instead of betting with real money you use play-money credits. You can’t win any real money playing demo mode, but it allows you to try out new slots for free to see if you like them before investing in real money wagers.
Demo mode also lets you practice your favourite online slots to better learn their mechanics without risking any cash. Using demo mode is a great way to avoid unnecessary spending, exercise reasonable caution around new slots, and gamble responsibly.
Payouts and Return To Player
How much an online slot machine pays out is measured by its Return to Player (RTP). Expressed as a percentage, RTP tells you how much of each wager you’ll earn back as winnings, on average. For example, if an online slot game has an RTP of 95%, you can expect to win $0.95 for every $1.00 wagered.
RTP is a key factor in evaluating online slots. You should almost always opt for the highest RTP slots you can find to ensure you’re getting a good return on your wagers. Keep in mind that RTP is calculated as an average over an entire play session, so any given spin may vary in outcome, but over several spins your wins and losses will average out.
