Bonus Games: 2
Our Riches of Wonderland slot is a fantastic looking video slot that features 2 bonus games. There's a Bingo Bonus Game triggered by the Alice symbol while the Madhatter's Hat Symbol triggers the pick an item game.

Play Riches of Wonderland

In our games you will find a great selection of bonus games. 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 bonus games you would find in popular slots games in a casino.

Free Spins Bonus

This bonus feature is in many 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 is also a pretty common bonus game in slots games. 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 bonus 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 pick an item bonus rounds 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 bonus round or 50/50 bonus has a few variations. You 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 bonus game 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 through 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 and take into account the wind speed to try and hit the center of the target. 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, 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 bonus game is where you bet on the winner of a race, like horse racing or greyhound racing. This is another bonus round that is common on our site but not so common in slots games at casinos.

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 bonus game that is unique to Free Slots 4U. Our fireworks bonus round features in Fireworks slot and New Year Party slot.

We have two versions of the Fireworks bonus round. 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 bonus 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.

Bingo Bonus

Bingo is very popular, although we don't know of any slots games at casinos that have a bingo bonus round. So we made one!

The Bingo Bonus is what it says it is, you get to play Bingo in a bonus round. This bonus round can be found in our Bingo Slot. When playing the speed bingo bonus 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 bonus game.

Tip: Selecting manual mode will have higher prize amounts, plus 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 bonus rounds.

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 rounds.

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.

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.

All the Roulette games are from our sister site Roulette 4U.

Blackjack Bonus

Blackjack Bonus rounds can be found in our Blackjack Slot and also our Casino Slots Slot.

The Blackjack games are from our sites site Free Blackjack 4U. Spanish Blackjack is featured in casino slots slot.

Our Blackjack Slots game features Hi Streak Blackjack, Blackjack Switch, and European Blackjack.

Spin The Wheel Bonus

This bonus round is very much like the Wheel of Fortune. Simply spin the wheel and watch to see where it lands to show what you've won. Our Royal Vegas Slot features this type of bonus game.

We are continually coming up with new bonus game ideas. If you have an idea for a bonus game that you would like us to create in one of our games, simply let us know (using our Contact Us page) and we will see what we can do!
