Anyone who has watched Happy Days will remember the neon sign that rotated on the top of Al's Diner, but the one in this game will drive you even wilder as it's the game's Wild Icon. Hit 5 of them on a line to win up to 10,000 coins, whilst any individual Wild Signs can replace other icons to illuminate more winning lines.

One of the favourite things of the 50's were those brilliant ice-cream sundaes, and it's no wonder that Rival Gaming decided to leave us drooling for more by incorporating these treats into the game as the Free Games Icon. Hit 3 to 5 sundaes to trigger the Free Spins Bonus in which all prizes are tripled, with 3 sundaes triggering 10 free spins, 4 triggering 20 free spins, and 5 triggering 50 free spins.

And who can forget how the cool cats used to get about, with motorcycles and trucks both being iconic symbols of the times. And that's why they've both been used as bonus icons. Kick-start your bank by hitting 5 motorcycles to win the jackpot, or 3 or more red trucks emblazoned with yellow flames (oh yes!) to trigger the Drag Race Bonus in which you can select a truck to drive around the track. If you win or come second you'll win a prize, whilst if the bonus is triggered by 5 Trucks you'll also win 40x your total-bet.

You can even play at 1950's prices, as spin-stake start from as little as 0.01 coins a spin. But you can also choose your preferred spin-stakes by combining 1 to 20 lines, 1 to 10 coins, and coin-values ranging from 0.01 to 0.25.

If you love the 50’s then you’ll definitely love this slot game version, and Rival Gaming have done a great job of incorporating some of the most nostalgic items of the times to use as bonus symbols. The bonuses are great fun, too – and, in true Fonz style, it gets a double thumbs-up from me! Canada seems to agree with me - this is very highly played slot North of the border!
