Jurassic Wins Online Slots

Can you smell that? It extincts like dinosaur dung around here! Although, we did expect the stench when we set up our own enclosure full of delightful dinosaurs for you to gawp at in our exclusive online slots game, Jurassic Wins.

Set over 9 win lines and featuring a roarsome multiplier mini-game, this slots game is sure to make you saur. Download this dino treat to your smartphone or tablet today and get spinning wherever you prowl.

Mr Spin’s Free Spins Casino clearly underestimated these reptiles when he built their enclosures. They’ve run amok in their pens and now find themselves part of a 5 reel slots game! All he wanted was some obscure pets to show off to his friends.

Getting Started

We might have gone way back to the Cretaceous period but Jurassic Wins isn’t any less portable or compatible than the rest of our exclusive slots games. Built in-house by our team of developsaurs, Jurassic Wins is optimised for play on-the-go and is compatible with 99% of smartphones and tablets.

To get started, press ‘Bet/Lines’, then use the ‘+’ and ‘–’ buttons to adjust your bet and the number of win lines you’re playing across. Your total bet amount will be the value of your bet multiplied by the number of lines you’re playing, so for example you could bet 2p across all 9 lines for a total bet of 18p, or you could bet £2 across 5 lines for a total bet of £10, the choice is yours!

Once you’ve configured a bet amount you’re happy with, simply tap the spin button to watch the reels spin and stop at random. Bets start from 2p a line and go all the way up to a maximum bet of £2 a line.

How to Play

After you’ve decided how much dino dough you want to pony up for your total bet amount simply tap the spin button. The reels will then spin in and eventually stop at random.

Win lines start on the left and winning combinations will pay from left to right. Winning combinations depend on the symbols that have spun in, with some paying out with 2 or more symbols in a row and other paying out on 3 or more matching symbols in a row on any active win line.

We’re not fossils here at Mr Spin, so we’ll be sure to highlight your winnings on reel, before adding your winnings to your account.

Reel Wins

Your winnings are set to ‘saur if you roll in a winning combination of symbols, because your original bet will be multiplied to the value of the win associated with the combination of symbols you roll in. You can find out about the value of winnings attached to each symbol combination in the Jurassic Wins paytable. You can access this by pressing the menu button and then ‘Paytable’.

Mr Spin’s prehistoric pets might be vicious but he’s not, so – if they’re present – he’ll add up wins from multiple win lines to give you a total win amount, you’ll only get the highest win from each individual win line though!

Wild Symbols

You’ll be going as wild as the beasts in Mr Spin’s enclosures if you spot Wild symbols next to some matching symbols in an active win line, as Wild symbols substitute for every symbol in the game to make up a relevant win.

Let’s say you have two Queen symbols on an active win line, this wouldn’t be enough to bag a win, but if they were adjacent to a Wild symbol along a win line this will count as three Queen symbols and you’ll have a win!

Just be aware, Wild symbols cannot substitute for mini-game or Free Spin symbols and you also cannot win the progressive Mega Jackpot with a Wild symbol in place of a standard Jackpot symbol.


Line up two or more truck symbols on any active win line and you’ll enter Dino Dough! It’s a race against our resident rex to pick up the highest multiplier possible!

Tap ‘Move’ to roll the dice and decide how far around the rex’s enclosure you move. You’ll collect whichever multiplier you land on. Continue moving around the enclosure collecting as many multipliers as possible, they all add up to increase your original bet by up to 400x.

Watch out for the ‘collect’ tiles though, they’re not strong enough to keep our small armed friend in his cage. He’ll break through there and your truck will become his dinner, leaving you to trudge back to the main reels.

Free Spins

Spin a winning combination of our fossilised Free Spins symbol on an active win line and you’ll bag some clawsome free spins! 3x Free Spins symbols gives you 5 free spins, 4x symbols award 7 free spins, and 5x symbols will grant you 9 free spins. The value of your free spins will lock to your last bet value across the same amount of win lines.

You’ll be hosting a prehistoric party when you hear about the additional free spins you could be bagging as a casino no deposit welcome bonus of up to 50 Free Spins No Deposit required*!

Once you’ve found your favourite and decide to make a deposit, Mr Spin will match it 100% up to £100!**

Gamble Feature

Our developers aren’t fossils, so they’re always looking to keep things fresh. So that’s why they’ve included a Gamble feature in Jurassic Wins. Simply select the type of wins you’d like to gamble on and if they roll in you can choose your bet for a chance to win 1.5x, 2x, 3x, 4x, 6x, or 12x your original total win.

Whenever you achieve a feature win in the game, you have the option to enter the gamble feature to stake your winnings. If you do not wish to gamble your winnings you can adjust setting accordingly and keep all of your winnings when they spin in. Similarly, if you’ve entered the Gamble feature and wish to keep your winnings simply tap ‘Collect’ and your original winnings will be added to your account balance and you’ll be placed back at the game reels.

You cannot enter the Gamble feature on Mega Jackpot wins, or for wins worth over £200.

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.
