Slot Games with Bonus Rounds
Slot games, in general, can be divided into online slots with bonus rounds and online slots without bonus rounds.
Slots with bonus games are usually more attractive for players and more fun to play because of the bonus rounds. They’re exciting because you’re always waiting for the bonus round to land and always expecting to win big in the bonus round.
All bonus slots usually have an explanation what the bonus round is about in the game rules. If you want to see what the bonus round is first hand, it’s best to try the games in the free mode first.
How do slots with bonus rounds work?
In order to see what a bonus slot is all about all you need to do is to sign up for an online casino and play the game for free. It’s the same as playing for real money. The only difference is, you don’t have to invest any money. You can read the game rules and the bonus round rules and once you feel comfortable with the game, you can give it a try in the real money mode.
In most video slot games, the bonus round is triggered when three or more scatters or bonus symbols appear on the reels. Once this happens, the bonus round starts and all you can do is to enjoy the privilege and hope to win big.
In general, the bonus rounds are divided into free spins and cash pick bonuses. The free spins bonus is a rewarding round where a player gets a certain number of free bonus games. There are also some other features like multipliers, extra wilds or expanding wilds. The cash pick bonus game usually awards cash prizes for every pick on the reels.
How to win big in the bonus games
One of the most fun features in the online slot machines is the bonus rounds. You get to view secret graphics and gameplay and you are usually given a chance to multiply your potential winnings.
However, did you know that there is a strategy for making the most of these opportunities?
If you don’t believe us, just check out the following…
1. Know your slot
Become familiar with your game and get an approximate feel for how often the bonus round appears. That way you can gauge if the game is being generous or stingy with bonus round appearances when you’re in the midst of playing it. If it’s not giving out too many, it may be time to move to a different slot as the first step to making the most of bonus rounds is actually getting to play them.
2. Use a bonus round hunting strategy
Many professional gamblers sight ‘bonus hunting’ as their chosen strategy when playing online. The beauty of this strategy is its simplicity; play a game until you get a bonus round, win and then leave.
The theory behind this is that you’re leaving every game after getting a reasonable win and each one of those wins add up to increase your overall bankroll, thus giving you more money to hunt more bonuses.
3. Play every line
Of course, it makes sense that you should try to maximise your chances of getting into these bonus rounds. One simple way to do that is to play every line. There are games that only offer bonus rounds to those who max bet, so if your budget is low, give the penny slots a lash and you never know, you might be playing with a bigger bankroll before you know it!

Bonus Rounds Slots FAQ
What slot machines have the best bonuses?
The great thing for players is that there are a huge number of slots with fantastic bonuses. We couldn’t possibly list them all, but here are a few examples of some amazing bonus rounds. NetEnt’s Dead or Alive has one of the most lucrative with proven wins of 100,000x the stake up for grabs.
Razor Shark from Push Gaming has another amazing bonus round stacked with free spins and multipliers that is capable of hitting 50,000x the stake when things go well.
Finally, Lil Devil from Big Time Gaming has an exhilarating Heartstopper Free Spins bonus round that is also capable of wins up to 50,000x the bet. Check the reviews here to find plenty more great bonuses.
What are the luckiest slot machines?
Some players may view this as a good or bad thing, but there is no such thing as lucky or unlucky slots. Modern, regulated slots are driven by unemotional Random Number Generators. These math models are completely fair, random and unpredictable.
It is possible to have runs of wins or loses, but this does not make a slot lucky or unlucky. Some slots have paid out more than others, such as Mega Moolah. But this is due to their bonus system, and the algorithms that govern play. Never luck.
What are branded slots?
Branded slots are slot games that use some type of famous element in their theme. This could be anything from movies, TV shows, video games, board games, cartoons, bands, and more. Branded slots are popular because they are instantly recognisable and relatable.
When it comes to bonuses, wins, and gameplay, it doesn’t mean they are necessarily better than non-branded slots. But there are some cracking good examples of branded slots all the same.
Are slots random?
Modern slots offered by licensed providers are completely random. Developers power their products using Random Number Generators that ensure that every spin is completely unaffected by the spins that preceded it. For extra peace of mind, online slots and providers are tested by third-party auditors as part of licensing requirements. This ensures that slots are totally fair and random.
Which slot machines have the highest RTP?
When it comes to RTP, 96% has become the unofficial industry average. Anything above that is considered good. Anything under that not so good – depending on how much less of course. The great thing for players is that there are loads of slots that score higher than 96%.
Some excellent examples that were released quite recently include Jackpot 6000 (98.9%), and Mega Joker (99%) both from NetEnt. Another generous slot is 1429 Uncharted Seas (98.6%) from Thunderkick and Retro Reels Extreme Heat (97.5%) from Microgaming. RTP is always a critical stat we look at when reviewing slots.
Do casinos manipulate slot machines?
Regulated, legitimate casinos do not manipulate slot machines. Slots machines have a house edge built-in, so there is no need for anyone to manipulate them. Regulated casinos have slots tested by independent auditors to prove that their slots produce the results they state.
If a casino was accused and found guilty of manipulating slots they could go out of business. It is just not in their interest to manipulate their slot machines.
Should you max bet on a slot machine?
You should only max bet on slot machines if it suits your bankroll limit and betting style. In the past, some slots would only trigger jackpots or bonus features on max bet. Nowadays, this is virtually non-existent.
Now, bet levels of any size have the same chances of launching bonus rounds, free spins, and jackpots. This also includes hitting progressive jackpots. Of course, you should always read the paytable of any new slot to make sure you are clear on the rules.
Here you can see and play all our free slot games with bonus features, no download or no money required. Basically, any slot games with bonus features, meaning any types of bonus symbols or feature is listed on this page.
This selection of our free games online offer a wide range of different bonus games. Each makes a real difference to the games.

Therefore, it is best to make sure you are playing on a free wifi connection.
In our games, you will find a great selection of bonus features. Some of them are completely unique, to our knowledge they have never been used in an online casinos slot game. Others are the same as the features you would find in popular slots games in a casino.
Free Spins Bonus
This bonus feature is in many free casinos slots games. Both in our own games and in the slots you will find in casinos. It is pretty much what it says it is. You get a number of free spins awarded to you.
Normally to active free spins mode you have to get a specified symbol to land on the reels a certain number of times. The number of times the symbol displays on the screen at the same time normally dictates how many free spins you're awarded. For example in our Football Fever Slot, 3 stopwatch symbols or more wins you free spins. 3 wins you 3 free spins, 4 wins you 5 free spins and 5 wins you 8 free spins.
When the free spins mode is activated there is normally nothing for the player to do. They just sit back and watch as the free spins are automatically played for them.
In some free spins modes, wins can be multiplied and sometimes more free spins can be won inside the free spins mode. This is known as retriggering free spins. There are many slight variations of the free spins modes.
Pick An Item Bonus
Pick an item bonus rounds are also pretty common in our free slot games with bonus features. They are also pretty common in slots machines in casinos. You're shown a selection of images to pick from.
Depending on the game, you get to pick one or more of the items. Each item has a prize hidden in or behind them, clicking the item makes the prize credit amount to appear.
Each time you activate the pick an item round. The prizes behind each item change so they are not the same each time. Depending on the game, the items may stay in the same position or switch locations.
Many of our games have a pick an item round. Including Monopoly Slots, Girls Best Friend Slot, Cleopatra Slots, and Pirates Slots to name just a few.
Gamble 50/50 Bonus
Another common type of bonus. The gamble round or 50/50 feature has a few variations. You can also find this bonus round in our free slot games with bonus features. The aim is to gamble the credits won by the spin that activated the bonus game. You can either keep your winnings or gamble them all for a 50/50 chance of doubling them.
In our 50/50 gamble games. There is a card face down, you have to select if it's a black or red card. You can also select which suite you think the card is. If you select correctly you double your winnings and get the chance to guess again on another card. If you guess incorrectly you lose all your winnings and return to the reels.
We have several games that feature this type of bonus feature that gets activated after every winning spin. Some of the games that have this are Flash Cash, Halloween Party, and Summer Spins
Shooting Bonus Round
Although this type of bonus round is pretty common on our site. They are not so common if at all on slots games in casinos.
We have several different types of shooting bonus games. Each requiring slightly different skill levels. Some are shooting type of games where you have to throw or shoot something at an object. Others are where you just have to click on moving items.
One of the highest skill level shooting bonus games is our Archery game in Summer Games Slot. You have to aim, judge the power of the shot. Taking into account the wind speed to try and hit the center of the target. Like reel Archery, the closer to the target you get the higher your winning credits.
Our snowball fight bonus game is unique to our Snowball slot. Once activated you get to take part in a snowball fight. You're represented by a little person with a red top, your opponents wear blue tops. You move your little person around on the screen and click on them to prepare to throw a snowball. When you let go you throw a snowball at the opponent. There are many rounds in the bonus game, each round getting progressively harder.
Racing Bonus
A race game is where you bet on the winner of a race. Like horse racing or greyhound racing. This is another unique feature that is common on our site. However, not so common in slots games at casinos. At casinos, these types of games tend to be betting games in their own right. They don't tend to be part of a slot as a bonus round.
In our Summer Games Slot, you bet on a swimmer by selecting which country you think will win the race. The position your selected swimmer finishes in determines the amount you win.
In Santa's Super Slots you bet on which toy you think will win the race. You get to place different bet amounts on different toys. When the race ends the positions that the toys come and the amount that you have bet determines the amount you win.
Fireworks Bonus
This is another game that is unique to Free Slots 4U. Our fireworks round features in Fireworks slot and New Year Party slot.
We have two versions of the Fireworks game. One version is based on the river Thames in London. While the other lets, you pick from London, New York, Paris, and Sydney. Each location features iconic landmarks as the backdrop to your fireworks display.
In the fireworks round, you get to build a fireworks display. By buying fireworks with credits from a fireworks fund. You place each firework on a timeline at the bottom of the game. When you're happy with the positioning of the rockets, simply hit Start Show. Then sit back and watch your very own fireworks display. The more fans you please with your fireworks display, the more credits you win.
Photograph the Reels
The Photograph the Reels or Shoot the Reels bonus game is pretty unique and fun type of bonus game. In this bonus game, the reels will spin up and down randomly both fast and slow. The aim is to click on a specific image as it whizzes past on the reels. The more you manage to click the more points you earn in the bonus round. This game is very much so a skill based game. It relies heavily on a keen eye and quick reaction time.
As you can see from the screenshot to the left you can play this game on our Slots of Vegas Slot. However, it is also featured in our Crazy Vegas slot. Even though all our games that have this type of bonus game each feature the word 'Vegas' in their names. This is just a coincidence. Although, we have not been to Vegas to check we are pretty sure the chances of finding this type of bonus game in Vegas is pretty slim.
Stop Flashing Light
This bonus game is similar to ones found in fruit machines. In the form of a Cash Ladder and Bonus Trail or Bonus Board. The stop the flashing light type bonus game is pretty much what it sounds like. There is a set of images that are darkened out and flash bright one at a time randomly. As they are flashing you have to click on a stop button to stop them on the correct image. Some bonus games such as the one pictured to the left show you which image you need to stop the light on. In other games, each position has a different bonus amount. Where the image you stop the light on dictates the bonus amount you win.
Our Slots of Vegas Slot slot have the type of bonus game shown in the image. Our fruit machines games have the type where the image you stop on shows the bonus you win.
Bingo Bonus
Bingo is very popular, although we don't know of any slots games at casinos that have a bingo round. So we made one! Casinos do have bingo games but they are not part of a free slot machine.
The Bingo Bonus is what it says it is. You get to play Bingo in a bonus round. This round can be found in our Bingo Slot. When playing the speed bingo round you can manually daub numbers on your bingo card, or you can select auto-daub. Look out for three bingo bonus symbols on the reels as this activates the feature in the game.
Tip: Selecting manual mode will have higher prize amounts, plus, we think, its more fun!
Video Poker Bonus
There are many video poker games in casinos. But again to our knowledge, none feature as a bonus round in a slots game.
Two of our slots, Casino Slots Slot and also Video Poker Slot feature video poker feature.
Video poker slot includes Deuces Wild Multi-Hand and Jacks or Better.
Casino Slots features Aces Faces video poker as one of its many bonus features. All the poker games are games from our Free Video Poker 4U sister site.
Roulette Bonus
Like video poker, roulette is another game that tends to be a game in its own right. So in true FreeSlots4U style, we have made it a bonus game in our slots machines.
Our Roulette Slot and Casino Slots Slot. Roulette slot features three versions of Roulette, French Roulette, American Roulette, and European Roulette. Casino Slots Slot features European Roulette.
