Tumbling Reels, Ultimate Payback and Loot Lines have changed gaming
The recent launch of Dungeons and Dragons: Crystal Caverns has reopened an old debate.
If you didn't know already, this online slots newbie uses the groundbreaking Tumbling Reels feature first uncovered on Da Vinci Diamonds.
But what is the most innovative online slots game of them all?
Could it be Da Vinci Diamonds, or have more recent titles like Transformers: Ultimate Payback and Super Hoot Loot taken the online casino experience to a whole new level?
First, let's look at the Tumbling Reels feature from Da Vinci Diamonds.
In a break with tradition, you don't spin the reels in this online slots game but watch as symbols drop into place.
And Tumbling Reels take full advantage of the internet's possibilities because images on winning paylines magically disappear and are replaced with new ones.
This means you can win several times from a single spin in the main game.
Another feature worthy of mention is the engrossing bonus on Transformers: Ultimate Payback.
All you need to do to trigger Ultimate Payback is get a bonus symbol on the first and fifth reels, at which point Optimus Prime and Megatron will stomp into view at the bottom of the screen.
Then, every time a fight symbol appears on the fifth reel, these steely-eyed warriors do battle until just one is left standing.
If you correctly guessed which Transformer won, prepare for an epic payout.
Finally, there's the Loot Line to consider. Available only on Super Hoot Loot, this is basically a supremely generous bonus payline.
Whenever an image featuring Hoo the Owl appears on the main reels, it will also be added to the Loot Line.
Even better, any wins you get on the Loot Line will be multiplied by the total number of credits bet, which could be anything up to 200x.
So those are three of the main contenders for the crown.
Whether you think the most innovative is Da Vinci Diamonds, Transformers: Ultimate Payback, Super Hoot Loot or another online slots game entirely, there's no doubt that great ideas are coming thick and fast right now in the world of online slots.
