What Bonus Rounds Are Offered?

Usually, a bonus round is a package of free spins. It can be a big or a small package with variety of other rules, but generally players get 20 spins which can be retriggered one or several times. To retrigger the feature, certain elements must be collected.

Pick and Click type of bonus rounds are less common, but are still popular. Once activated, players are offered a selection of different objects to choose from. In some cases players pick just one object, but sometimes multiple selections are allowed and the round is over once Collect symbol is revealed.

Slots with Adjustable Risk Bonus Features

There are casino slots that let players set the desired risk level for the duration of the bonus. Risk-averse punters would prefer more spins and lower multipliers. Risk-lovers can choose fewer free rounds in combination with highest multiplier.

When playing Jungle Spirit: Call of the Wild by NetEnt, for instance, you’ll have five choices. The smaller number of spins the higher risk. But the potential maximum reward increases with the risk level, and for some it’s definitely worth chasing higher payouts. Slots like Jungle Spirit are a great option for those who want some control over how things develop. But there are also video slots which leave that to chance as risk level is selected randomly.

Re-spins are another type of slot bonus feature. Today, however, they aren’t as popular as they used to be. Usually this feature is free and all or almost all reels re-spin at the same time. But best option is when slots offer to re-spin each reel separately. That will cost money, but it is sometimes worth spending extra credits, especially when you are close to winning big. Book of Oz, one of Microgaming slots,has this type of bonus game.

Extra Features in Slots with Bonus Rounds

Bonus games during which some extra features get activated aren’t uncommon. These can be variety of features like extra wild symbols, sticky wilds, mega symbols 2×2 or bigger (Wild North), multipliers, including unlimited multipliers like in White Rabbit by Big Time Gaming. Low paying symbols can disappear for the duration of a feature making bigger payouts more likely. There are also tons of other interesting features available in bonus games.

Fortune Wheel Bonus Features

Fortune Wheel is a quite popular type of bonus in slot machines. This feature is used by many big and small developers. Maximum potential of this type of round vary considerably. Some offer maximum a few hundred dollars while others can pay multi-million jackpots. There are also different shapes this wheel can have. Guns N’ Roses by NetEnt, for instance, has a vinyl record styled fortune wheel.

Mega Fortune and Mega Fortune Dreams at NetEnt casinos offer millions of dollars to those fortunate enough to activate bonus and then reach the center of the wheel. There are three sets of circles; players advance closer to the inner circle for better prizes or get stuck early and collect certain amount of credits or one of smaller jackpots.

Another famous jackpot, Mega Moolah, can also be hit after a single Fortune Wheel spin. But unlike Mega Fortune, this time the wheel doesn’t have multiple levels. Once you enter the game, you are sure to hit a jackpot. However, there are four types of jackpots and you can win a million dollars as well as a few hundred dollars.

Slot Machines with Multi Level Bonus Games

Some online slots have multi level bonus rounds. Players are given certain tasks one after another, and by completing each of them they advance further to win bigger prizes. Who Wants To Be A Millionaire, available at Big Time Gaming casinos is one of such titles. Just like in the TV show of the same name, this slot offers lots of multiple choice questions and several lifelines (50:50, Ask the Audience and Phone-a-Friend).

There are other slot machines with similar bonus rounds. Look for Hot as Hades at Microgaming casinos. Players will have to pass through different stages and in the end find the crystal helmet.

Paying to Enter Bonus Games

Over the last few years slot machines offering the opportunity to buy a bonus feature gained popularity. Any time players want to trigger the round, they can just pay certain amount of money instead of waiting for as long as it takes to land a required set of symbols. This feature is available in Fat Santa that can be found at one of Push Gaming casinos. A package of 5 free spins will cost you 80x bet. But the great thing is that Santa in this slot can grow until the symbol covers the whole screen.

Extra Chilli and Vikings Unleashed are two other titles worth considering. Players don’t just buy bonus games, but can also take extra risk trying to get more free spins and higher multiplier. Other slots with similar feature are: Buffalo Rising, Joker Strike, Yak Yeti and Roll, Dark Vortex, Champions of Rome and some others.

Collect Symbols to Trigger Bonus Games

Players can earn their way to the bonus game. When playing certain slots, you will be asked to collect a specified number of the same symbols to activate features. Vikings Go Berzerk and Vikings Go To Hell by Yggdrasil both have this type of bonus activation method. There are also Bumper Crop by Playson and Eye of the Kraken released by Play’n GO.

Risk Game in Slot Machines

Risk game is one of the bonus rounds. It used to be very popular, but not anymore. Today there aren’t many new slots offering double-up feature. It’s an optional feature and gives a chance of doubling your win and otherwise losing it.

Players are offered to take risk after each winning combination. Usually to double the win they need to guess if a playing card suit is of black or red color. Sometimes it’s also possible to guess a playing card suit and quadruple payout. At Play’n GO casinos, for example, you can find Rage To Riches slot machine with a risk game allowing to double or quadruple winnings.

But the Untamed series of slots by Microgaming offers the most advanced risk game feature. Untamed Bengal Tiger, Untamed Giant Panda, Untamed Wolf Pack, Untamed Crowned Eagle all let players decide how risky the bonus game will be and how much they can win.
