King Henry himself is wild and substitutes for all symbols except the scatter symbol. If you manage to spin 5 wilds on an active payline, you take 30 x the total bet.
The 6 queens of King Henry VIII are the premium symbols: a 5-of-a-kind of these ladies is worth between 15 x and 30 x the bet.
There are 4 low symbols: the card symbols of hearts, spades, diamonds and clubs. These pay out between 1.5 x and 3 x the total bet with 5 of the same.

Battle Royal has 3 bonus features, 1 mini feature and two main bonus features. The mini feature is called Royal Flush and in this case has nothing to do with video poker or with flushing royal toilets. The Royal Flush is triggered at random times and causes all low symbols to turn into the same symbol. These can be both low and premium symbols.
If you spin two scatters (1 on reel 1 and 1 on reel 5), you will win the Long Live The King bonus or the Heads Will Roll Bonus.

The Long Live The King Bonus is an old-fashioned pick and click bonus:
Choose treasure chests for keys or cash prizes
The keys give access to higher levels
With cash prizes you not only get money but also a ghost appears
The ghost (one of Hendrik's beheaded women) tries to take Hendrik. If successful, the king turns into a measly pile of bones and the bonus is over.

With the Heads Will Roll Bonus you get an unlimited number of free spins. Before entering the bonus, you get to pick 1 of 6 women. If your choice survives the bonus round, you will win a cash prize.
During the free spins, the guillotine can fall on 1 of the women. Once this happens, this lady will be decapitated and will remain wild for the rest of the free spins.
But if 5 ladies are beheaded, the free spins are over. The trick is to get 3 or 4 queens wild and avoid the guillotine for as long as possible.
After the free spins have ended, there is still a big final. Hendrik is allowed in a last attempt to behead the surviving husband. If you succeed, you're in luck: you now get free access to the Long Live The King bonus. If it is not successful, the bonus is really over, and the final balance is drawn up.

Battle Royal has the classic video slot setup of 5 reels with 3 rows of symbols. There are 20 fixed paylines and you pay a fixed amount per spin. The minimum bet is 0.20 euros per spin and you can bet a maximum of 100 euros per spin. It is possible to win big on this slot: the highest possible payout is 5,000 x your total bet. With the maximum bet, this equates to a top prize of 500,000 euros.
However, the chance that you will win it is not very big: according to Play'n Go itself, it seems to occur once every 100 million spins. Good luck with that. The variance is medium, and the payout percentage is 96.56%. That's an excellent Return to Player.
