What are the Best Features of Slots?

Special bonus rounds and features make online and mobile slots more exciting, captivating and entertaining. There’s so much more to features and The Slot Buzz explains how each bonus round significantly boosts your chances of winning. Let’s get down to the nitty-gritty details of the most favoured online casino slot features and bonus games.

Expanding Wilds

The number of different wild symbols increases regularly, and instead of just standing in for others to increase chances of winning, wilds bring even more added benefits. Expanding wilds can expand to cover an entire reel, which significantly raises the chances of combination wins. One of the most popular online slot games to feature expanding wilds is Starburst by NetEnt.

Cascading Reels

Cascading reels are a most loved feature also referred to as cascading reels or an avalanche feature. Once payline wins are awarded, the symbols part of a winning combination disappear and the spaces get filled by symbols dropping from above. It created the perfect condition for brand new combination wins to form without risking an additional bet. The best online slot offering the cascading reels is Gonzo’s Quest by NetEnt.


Megapays slot machines display the jackpot values above the reels included in the base game, these include mega, major, midi and mini jackpots. In mega pays the jackpot values take 0.9% of the RTP of the slot and the jackpot is awarded randomly. One of the most popular Megapays slot games is Bonanza Megapays™ by BTG.

Bonus Buys

Bonus buys appeal to all slot fans who want the best features fast, and players who find waiting for features a major challenge. Bonus buys are a shortcut that gives players the power to activate the free spins bonus round when and as often as they wish at an additional cost. One of the most enjoyed bonus buy casino slots is Winds of Wealth by Betsoft Gaming.

What Are Bonus Games on Slots?

The most exciting bonus rounds offered by the best online slots come in a variety of formats and styles. A Lucrative bonus round can require either no or some player interaction, which makes it possible for players to feel they have some say in the outcome.

The main function of bonus rounds is to add adrenaline-pumping action, these are fast and often guarantee extra profits. An exciting bonus round can relate directly to the game theme, unlock a mega number of ways to win or activate bonus wheels that could trigger progressive jackpots. The most wanted bonus game in slots remains the free spins bonus round.

How Do Bonus Games Get Activated?

Depending on the bonus game structure or type of bonus games, some activate via bonus symbols identified on the paytable of the slot machine. Once the required number of symbols appear on the reels, entrance is granted into the in-game bonus games and UK players get to collect the bonus payout before returning to the main game.

Pick n Click Bonus

One of the best examples of a pick-n-click bonus feature can be found in the Jimi Hendrix online slot. Activation takes place when three or more scatter symbols appear on reels three, four and five. In the bonus round appears loudspeakers and the goal is to reveal three matching symbols to win activation of the three free spins bonus rounds or coins.

Arcade-Style Slot Game Bonus Games

Arcade-style bonus games are one of the more interactive video slots bonus rounds created by top software developers. The highly popular slots bonus game comes in a variety of arcade game styles and provides players with a bonus game within a game. The level of activity varies and so does activation. While most activate via three or more scatter symbols others trigger randomly.

Online Slots Free Spins Bonus rounds

Online slots with free spins bonus rounds remain the hot favourites. The number of variations is endless top slot games continue to introduce online slot fans to interesting new ways to winning via free spins. Activation ranges from scatter symbols to an array of other ways to unlock free spins.

One of the best examples where free spins activate when two stacked wilds show up on the reels is Dracula slot. Retriggering the free spins bonus round requires two stacked wilds showing up on the centre reel. In Finn and the Swirly Spin online slot, free spin key symbols move to the centre and unlock a sky-city filled with different venues serving free spins.

How Do We Play Bonus Rounds

Most bonus rounds work on the same concept, three or more bonus symbols activate the bonus, no wagering is needed during the bonus and when it ends you collect your winnings. Randomly triggering slot machine bonus rounds are the most exciting since any spin could trigger the free spins or free respin or any other type of bonus game.

One of the bonus rounds often found in bonus slot games is the pick n match bonus game also referred to as the click-me bonus round. The prize up for grabs is not revealed immediately and the challenge is to reveal two matching symbols in the bonus rounds. Once the player succeed the prize is revealed and added directly to the player’s bankroll.

Types of Bonus Games From Slots

The different types of bonus rounds that add huge excitement continue to increase and evolve almost with every new slot release. Each of the bonus features brings a new way to enjoy an upsurge in winning chances without placing extra bets. Here are a few of my favourites:

Click Me Bonus: Click and unearth exciting prizes

Free Spins Bonus: Numerous spins via a single bet each with the potential to big

Jackpot Bonuses

Triggering the jackpot bonus round in a progressive jackpot slot is one of the most exciting moments. Progressive jackpot rounds offer the chance to win a massive payout via the spin of a wheel, pick and click style play or lining up a specific number of scatters or bonus symbols up on a payline, or the specified payline. The jackpot bonus round in some online casino slots can also activate regularly.

Reward Bonuses

Pick n reward bonuses combine mystery with anticipation, players get to uncover what hides behind a selection of identical icons. Depending on the video slot games, the prizes hidden behind the objects can award multipliers, extra wild symbols, coins rewarding bonus cash prizes, or you can win free spins.

Some reward bonuses require players to reveal two, three or more of the same symbol and the prize between the matched symbols is rewarded. A great example is the Hall of Gods video slot, where matching symbols award cash prizes, the midi jackpot, mini or mega jackpots.

Bonus Wheels

The bonus round everyone dreams of activating is the bonus game in Mega Fortune leading the way to a chance to win the rapid jackpot, major or the multi-million paying mega jackpot. It takes three or more bonus symbols to appear left to right from the first reel to enter the wheel spinning action. Instead of spinning the wheel, you need to stop it at the right moment.
