Play The Royal Promise for Free

A quick look at the prizes symbols and you'll realise that Prince Peter is offering Princess Philippa a trio of things including himself (how generous), a diamond engagement ring (okay he's getting there), and a prize stallion fit for any royal stables. The great news for all us slot players is that we can, of course, win prizes each time 3 to 5 of any of these proposal offerings line-up on one of the game's 40 possible pay-lines. Top prizes for each are 40x your line-bet for Prince Peter, 30x for the Prize Stallion, and 20x for the Rock on a Ring. In between waiting for the story to unfold through these themed prizes we can also add some smaller wins to the pot by lining-up some poker symbols. Bigger prizes are awarded when Princess Philippa turns-up on the reels at up to 50x your line-bet, whilst the Wild Royal Promise Logo pays up to 1,000x your line-bet. As a good Wild should, the Royal Promise Logos will also replace other symbols to trigger extra winning lines whenever possible.

If Philippa hasn't been completely swayed by the sight of Prince Peter, a diamond ring and the prize stallion, Peter has still got a persuader up his sleeve in the form of his family heir loom – a Royal Ruby so big it surely can't fail to impress!

It certainly impressed me as matching Ruby symbols on reels 2, 3 and 4 triggered 7 free games. You then get to choose one of the triggering Rubies to reveal one of the game's prize symbols. You will then see all stacked symbols on the reels change to this symbol – which could see you be awarded multiple winning lines all at once – and some serious prizes.

Despite the fact you wouldn't mind having a pop at the pretty Princess Philippa, sadly it's not possible, so choosing the right spin-stake is all about keeping to your slot-play budget and maximising your chances of winning at the same time. You've got a choice of playing 1, 10, 20, 30 or 40 lines on any spin, and you can stake each line with bets ranging from 0.01 coins up to 10 coins – simply choose your own perfect spin-stake.

The idea of marrying someone for money, or not, will always be the subject of much discussion, but luckily H5G have made the game so we can win whether Princess Philippa is impressed with Prince Peter or not, especially when the brilliant Super Stacks Feature kicks-in, so let’s hope we’re on a promise!
