🎰 Online Slots Game Types

Over the years, top software providers have developed a number of different types of real money online slots games. Some of the best and most popular real money slots types include:


Video Slots – A modern computerized version of a classic slot machine. Video slots usually incorporate a specific theme which consists of bonus games and additional ways to win.

Jackpot Slots – Known for giving out big paydays, jackpot slots feature either a fixed or progressive prize pool. A player can win the prize pool by triggering a special winning combination. Most jackpots are quite difficult to win but can get into the hundreds of millions of dollars.

Classic Slots – Old-school slots games that mimic playing at brick and mortar casinos in days past. Most classic slots have fewer reels and paylines and limited special features. Common examples include fruit machines and three-reel single slot games.

VR Slots – Using cutting-edge technology, VR slots immerse players in a 3D virtual reality mirroring the experience of a real-life casino floor. VR slots are generally extremely interactive and give players access to multiple games.

What is the difference between playing real money slots and free slots?

When you play real money slots games, you are playing titles that offer real money cashouts. To play real money slots, you will first have to make a deposit at an online casino.

Free slots are games that do not have any real money gambling but allow you to play the slot with free tokens. Generally, free slot games are used to ‘try before you buy’ by players to test out a slot.

How do online slots work?

Online slots apply Random Number Generator (RNG) technology to create random sequences every millisecond of the day. These sequences guarantee that the result of spins is truly random. So the result of your previous spins will have no bearing on your next spins.

How slot spin works:

  1. Player presses the spin button, and a random number is generated via RNG.
  2. The game software reads where the reels should stop based on the number.
  3. Reels stop where they should, and the game calculates the result of the spin.
  4. The player is provided with the net outcome of the spin.

🎁 Slots Bonus Types

There are two main slot bonus offer types that are popular amongst casinos in Canada:

  1. Deposit Bonuses
  2. Free Spins
