Before you start playing, it is important to choose the right bet for your playing style and your budget. The game's coin denomination ranges from $0.01 to $1, while the wager itself can be as low as $0.20 and go up to $20 per spin. Bear in mind this is a medium variance game, meaning that it offers well-balanced payouts and will appeal to the majority of punters.

Once you enjoy the film's soundtrack at the Frosty Palace, you'll encounter low-value symbols on vinyl, classic 1950s cars, and milkshakes, but also some familiar faces, such as Betty Rizzo, Kenickie Murdoch, Sandy Olsson and Danny Zuko. The list of symbols includes the ones featuring Danny and Sandy, as well the Wild which can substitute for all others except the Scatter.

The wide offer of features starts with the Rockin’ and a Rollin’ Respins feature, which is triggered whenever Danny, Sandy or Danny and Sandy symbol fully occupy the leftmost reel, resulting in 3 respins. The symbol that activated the feature will remain locked in place.

The Sweetheart Wild Symbols feature is activated at random during the main game and once it is on, you'll see 5 to 8 Wilds falling from above and added to the reels, which can lead to big payouts.

Now, the game is all about the Jukebox Bonus round, triggered when the three Grease Scatters land on reels 1, 3 and 5 at the same time. This will give players a choice of 3 bonus features:

Better Shape Up feature – this one awards 12 free spins with only high-value symbols and Wilds appearing on the reels. While this feature is active, all Danny and Sandy symbols transform into the Danny and Sandy joint symbol.

Summer Nights feature – a total of 4 free spins is awarded, with the Sweetheart Wild Symbols feature being applied on each of the spins. This means between 5 and 8 wilds are added to the reels on every free spin.

Rydell High feature – this is a pick me game, where you'll choose photos from the yearbook to receive cash prizes. Every time you make a successful pick, you'll advance you to the next stage where bigger prizes are on offer!

Last, but not the least is the Greased Lightning Jackpot feature, accessed at random during the Main Game, where you can win 1 of 2 progressive jackpots, Danny’s Jackpot or Sandy’s Jackpot.
