Getting Started

Getting started on your headhunting adventure in Shrunken Trails online slots is easy. First up, set the number of win lines you want to play across and a bet-per-line. This can be anything from 2p a line up to a maximum of £10 a line, and is adjusted by tapping ‘Bet/Lines’ button and using the ‘+’ and ‘-‘ buttons.

As you do, you’ll see the figure in your ‘Total Bet’ box increase and decrease automatically. This figure is worked out my multiplying your bet-per-line by the number of active win lines selected. Say you bet 10p a line across all 20 win lines; your total bet will be £2 a spin.

How to Play Shrunken Trails

Ready to take a walk on the wild side, intrepid explorer? Great! Now you’ve set a bet you’re happy with, tap the spin button and heads – or should that be symbols? – will roll in and stop at random.

Much like the Witch Doctor beating a rhythm on his jungle drum, there’s an easy-to-follow pattern when it comes to the win lines in Shrunken Trails – they always pay from left to right. And those wins will always be displayed on screen before being automatically added to your credit.

Exactly which of our rainforest-themed symbols you need to line up to bag a win depends on what they are. For some, you’ll need a 2+ combination whereas you’ll need 3 or more of others. Tap the menu button in the top left corner and then select ‘Paytable’ to find full details.

Reel Wins

There’s more than shrunken heads in this rainforest, you know! Brave explorers will also discover that some really wild wins are hiding in this Mr Spin Online Casino exclusive, and each winning symbol combination awards you a different multiplier of your original bet-per-line.

What that multiplier is exactly, depends on the combination of symbols – which take the form of shrunken heads or jungle inhabitants – lined up on your active win lines. You’ll find full details of all multipliers in the paytable.

Don’t lose your head, but Mr Spin is a pretty generous guy, which is why if you win on more than one active win line with a single spin, those multiple wins will be added together and added to your total credit. Witchcraft won’t help you here, as only the highest win on a single line will be paid.

Wild Symbols

Keep your eyes peeled for the eye-popping shrunken head rolling in on to the reels. He may look like someone you’d want to avoid, but you’ll soon realise he’s actually pretty good company to keep. Why? Because he’s the Wild symbol.

That means that he can substitute for most of the other jungle symbols and could help turn a losing spin into a winning one. Line up the Wild alongside a pair of toucan Js, and you’ll win the multiplier you would have if you’d had three toucans all along.

Now, don’t go making a Mr Spin voodoo doll, but it’s important you know that Wilds won’t substitute for the Mini-Game or Free Spins symbols. You also can’t win the Mega Jackpot where a Wild lines up with four Jackpot symbols.


If you follow the jungle drums – and our rainforest explorer – you might just stumble upon the Treasure Trails mini-game.

Hidden deep within the rainforest, this mini-game activates when you line up two or more explorer head symbols on an active win line. The more symbols you line up on the reels equals larger multipliers in Treasure Trails!

The aim of the Treasure Trails mini-game is simple: move the voodoo doll around the trail, collecting multipliers as you go. Press the spin button to find out how many spaces the voodoo doll will move around the grid. Whenever you land on a multiplier, you win it and it’ll add on to your total.

There are some other squares to keep an eye out for too. If you land on a ‘Swap’, the tiles will swap to the other side of the board and your next roll will move the voodoo doll away from the centre. If you land on a question mark or large win, you claim the reward but that space will turn into a trap.

Try not to fall into any traps though! We heard on the jungle-vine that the Witch Doctor isn’t the nicest guy to bump into, so if you land on a skull and crossbones symbol it’s the end of the mini-game and you’ll return to the Shrunken Trails reels. Don’t worry though, you’ll collect all of your wins up to this point.

Free Spins

Spy a smiling skull symbol on your active win lines? He’s certainly a good friend to have around these parts, as lining him up will award you some free spins! Line up 3, 4, or 5 of him and you’ll receive 5, 10, or 15 free spins respectively!

These spins are paid for in jungle currency so your total credit won’t take a hit, but the bet amount and number of active win-lines will lock at your previous bet parameters. That’s not the end of this Free Spins feature though.

Mr Spin is always looking for ways to do things differently when it comes to his exclusive mobile slots, and this exciting Free Spins feature is just that! Once your free spins have begun, you’ll enter Head Hunter mode.

In this mode, the free spins symbol no longer awards free spins but instead, if you see this happy chappy anywhere on the reels, they’ll go into the cooking pot! As you add heads to the pot, you’ll climb higher up the rainbow magic ladder on screen.

You’ll keep adding heads to the pot whilst in Head Hunter mode, which ends when you run out of free spins. When this happens, your total bet will combine with the active prize on the magic ladder to award you a huge prize!

Progressive Mega Jackpot

The occurrence of “JACKPOT” symbols filling an active win line awards the progressive Mega Jackpot. The progressive Mega Jackpot is available on any bet, with 0.025% of the bet being added to the progressive pots. Half of the value gets added to the current jackpot, and half to a reserve pot ready for the next winner. When the Jackpot is won, it is reset and begins to rise again. Simultaneous wins can occur. If a player wins the progressive Mega Jackpot then a notification would occur BEFORE any other player was awarded the Jackpot. Any players in a game that contributes to that same Mega Jackpot will receive the on-screen notification of a reset the next time they press the spin button if it is within 10 minutes of the jackpot being won. Players will not be charged for the spin generating this notification. The Mega Jackpot guaranteed starting value is £100,000, with even higher starting prizes possible with a built up reserve pot. The Mega Jackpot promotional pot system is available over any stake on any participating game plugged into the Mega Jackpot promotional pot. In the event of a communication error after a progressive win result has been determined and before it has been displayed on screen, the win amount will automatically be transferred to the player’s account. While the game is live, the Jackpots cannot be terminated.
