10 Biggest Slot Machine Wins of All Time

Betway — Best online casino site in the UK for accompanying app

Condensing all the brilliant features of an online casino’s desktop site into an easy-to-use app is a task that’s almost impossible to perfect. Compromises with slimming down the breadth of variety on offer, splitting apps into specific casino genres or loading and gameplay are essential.

Betway’s ‘Casino Slots and Games’ app is arguably the best out there for providing a great depth and breadth of casino games and slots in one app whilst maintaining a look and feel consistent with the excellent online casino site.

Don’t take out word for it, the app has got a rating of 4.7/5 from more than 1,000 user reviews at Apple’s App Store.

Casino Slot Variations

In addition to the RTP, players also pay attention to variance. Slot machines pay out smaller winnings on a more frequent basis (low-medium variance) or more wins in a sporadic manner. Highly volatile slots can cause a lull in your winnings but also follow up with more substantial gains down the line. Jackpots tend to be the most profitable type of slot machines

Here’s a list of the most recognizable online casino slots and the different variations.

This lucky winner went to watch a basketball match but decided to branch at the Excalibur casino to kill some time before the game started.

He received an instalment payment of $1.5 million for the next 25 years. Fun fact is, this man was only 25 years old the time he won the jackpot, meaning he is automatically a rich man till he is 50.
