It's worth noting that whenever you visit the online casinos that feature these games, you can get the biggest and best bonuses that they provide when you use the links, or special promotional codes on the JohnnyBet site. Now, let's have a look at the best online slot machines.
1. Gladiator Jackpot
Based on the superb Russell Crowe movie from 2000, Gladiator Jackpot is packed with stirring images from the film, including Emperor Commodus, the Coliseum, and the iconic helmet worn by Maximus himself. The Coliseum acts as a scatter symbol, triggering a bonus game where players pick out stones on a wall to reveal a number of free spins, a multiplier and extra wild and scatter symbols that will apply throughout the free games.
The Gladiator Jackpot round can lead to riches. Just pick several of the bronze, silver and gold helmet symbols to reveal prizes, although if all 9 helmets are gold, then you win the progressive jackpot, which can exceed £1 million!
2. Marvel Slots
There are actually several Marvel Superheroes slots, and it's hard to choose which is best, it all depends on which character is your favourite. There are games based on Iron Man, The Incredible Hulk, X-Men, Captain America, Thor, DareDevil and more, all with different bonus rounds, thrilling images from the hit movies, and a four-level progressive jackpot.
As with the film, the Avengers slot features a number of the heroes in one place. With four free games rounds and a special prize whenever Thor, Nick Fury, Hulk, Captain America and Iron Man appear on a payline, this game is as action-packed as the movie. Each free spins game has its own features, with the Hulk Games dominated by a fixed wild symbol expanded across the middle reel, while the Thor Games have the Norse God creating extra wilds across the reels. During the Iron Man Games, Tony Stark will increase your win multiplier with each spin, plus there is a fixed wild across reel 3, and finally the Captain America Games have a multiplier award with each spin.
3. Everybody's Jackpot
This is a unique type of game, where the jackpot amount can be won by a single player, but part of it is shared between a few. The best part is that if you have wagered a qualifying amount on the game in the 24 hours prior to the jackpot being hit, you still share part of the prize, even if you are not currently playing!
Looking like a TV game show, Everybody's Jackpot is a 9 reel game, where all spots spin independently of each other, while a wild symbol increases the frequency of payouts by substituting for other symbols if it will create a win. Get three or more scatter symbols to trigger a free spins round, during which an extra wild symbol can appear in the middle positions. and these spins can be re-triggered if more scatters land on the reels during the round.
All of these titles can be found at William Hill Casino and EuroGrand Casino. When you visit William Hill using the unique bonus code BETEXVIP, they will treat you to the best welcome package that includes a first deposit bonus and free no-deposit spins.

Available at StarGames Casino, Sizzling Hot is one of the best online fruit machine style games that are such a speciality there.
