Hello Casino has recently added the latest classic themed slot machine, Big Win 777, to their casino. This vegas inspired 15 payline slot also comes with a healthy dose of modern features, meaning it should appeal to a slightly wider audience.

Big Win 777 uses a regular 5×3 reel array and comes with 15 fixed paylines. However, in classic slot style, the symbols can stop in positions, not on an active payline, sp prepare for several dead spins in the base game.

The big initial attraction from this machine is the frequently triggered bonus wheel which offers rewards up to 777x stake. However, they have also built a free spins bonus round into this slot triggered from the bonus wheel, and this is more than capable of producing some very nice wins, too, thanks to the spreading semi-sticky wilds features.

Thankfully the “Chance” bonus wheel is triggered fairly frequently in the base game and helped further by a randomly activated Booster Spins feature, making landing 3 scatters a lot more regular than you might expect.

The main bonus wheel has a variety of Bet Size related rewards that can range from as low as 5x right up to 777x stake, along with the ability to trigger the Free Spins round, which features a semi-sticky spreading wild feature that can produce huge wins when lots of wilds land in view on the same spin.

You can get a decent overview of this slots main features in the gameplay video below.
