Play Classic Slots Online

Many popular slot games from physical casinos are available online. These online versions are almost identical to the originals.

Convenient Access

There’s no need to travel to a casino. You can play online slots anytime from your PC or laptop, making gambling easy and convenient.

Higher RTPs Online

Online slots often have higher Return to Player (RTP) percentages than land-based slots. While land-based slots may have RTPs in the mid-80s, online slots can go up to 98%. This means better chances of winning when you play online.

Best Online Slot Mechanics & Features

Online slots all have a similar basic concept, but many have unique game mechanics and features that affect how you play and what you can win. Here’s a breakdown of the main features:

Base Game

When you start an online slot, you’ll see the base game. This includes the standard reel setup and symbols. The paytable shows how much each symbol is worth and what you can win for different combinations. The base game is simple: choose your bet size and start spinning. 

Bet Size

You can adjust your bet size to fit your budget. The bet size often includes:

  • Coin Value: Your coin amount starts as low as €0.01.
  • Bet Level: The number of coins you bet per spin.
  • Paylines: Some slots let you choose how many paylines to activate.

Winning Combinations

Most slots need at least three matching symbols for a win, though some pay for just two high-value symbols. Wins are usually formed by matching symbols on adjacent reels from left to right. However, there are other payout structures, such as:

  • Pays Both Ways: Wins are paid for combinations from left to right and right to left.
  • Cluster Pays: Wins occur when enough matching symbols form a cluster, regardless of their position.
  • Anywhere Pays: Matching symbols can be anywhere on the reels.
  • Scatters: Landing three scatter symbols triggers a bonus game. Some slots offer enhanced bonuses for four or more scatters.
  • Wilds: These symbols substitute for others (except scatters or bonus symbols) to create winning combinations.

Bonus Rounds

While the base game offers frequent payouts, the real excitement comes from the bonus rounds. These are triggered by landing three or more scatter symbols, leading to free spins and special features with bigger multipliers. Here are some common bonus features:

  • Expanding Reels: A special symbol can expand to cover an entire reel, increasing your chances of winning. 
  • Retriggers: Getting more scatter symbols during a bonus round can give you extra free spins. “Danger High Voltage” is known for this feature.
  • Jackpot Wheels: Spin the wheel to determine your bonus round. Games like “Sausage Party” and “Genie Jackpots” have multiple bonus rounds.
  • Bonus Gambles: Some games let you gamble your bonus for a chance at a bigger one or risk losing it. “Extra Chilli” and “Vikings Unleashed” at Party Casino offer this.
  • Upgrade Symbols: Certain bonus rounds remove or upgrade low-paying symbols, increasing your win potential.
  • Ladder/Trail: Collect symbols during the bonus to climb a ladder or move along a trail for better rewards. “Big Bass Bonanza” at Captain Cook Casino is a good example.
  • Link & Win: This feature, also known as Lock ‘n Spin or Hold & Spin, gives you three spins that reset with each cash symbol that lands. Microgaming slots often use this mechanic.
