How to Play: Rules & Our Software

Start your 15-20 Line Slots game by setting your coin amount – remember, your round costs one coin per activated line, so bear this in mind when specifying your coin value. Continue by activating your lines – you can activate just one line if you wish, or multiple – and use the Bet Max feature to activate all available lines. This is particularly important if you want to play for the progressive jackpot! Bet Max will automatically set your wheels in motion; otherwise hit Spin to get those reels moving!

When the reels stop, the symbols on your activated lines determine any special features and payouts. Your payouts are awarded automatically to your bankroll, so all you need to concentrate on is having fun, and you can see what there is to play for on the paytable at any time. If you triggered any special features, such as scatters, free spins or bonus rounds, your game will continue until you have completed them all. Many features can be re-triggered, so a single game can last for multiple spins, which means you get more ways to win! And with 15-20 Lines to activate, you can expect plenty of thrills and extras as you play.
