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.
