How We Review Slot Games

We test and rate all slot games across 5 criteria, assigning a score out of 10 for each and an overall score that is an average of the 5. To build an accurate assessment of each game we gather information from the supplier and play in real play or demo mode. Find out more.

Jawbreaker is a sweet-themed scatter pays slot from iSoftBet. With each spin up to 3 Jawbreakers with multipliers of up to 5x may land. Any win also triggers a tumble, and 6 of those in a row fill the gumball machine to unlock free spins. And during free spins, all Jawbreaker multipliers are added to another meter with the total value applied to each win. Payouts max out at 10,000x and you can spin from just 20p.

Testing Notes: Here’s What Happened When We Played Jawbreaker

IMPORTANT: To give you an accurate assessment of the games we review our writers play 200 spins. Whilst this is a useful tool to help us review games and to give an example of what might happen when you play, keep in mind that 200 spins is only a very small sample and cannot be used to accurately predict what might happen over another 200 spins. The outcome of all slots play is always random.

Boom Or Bust? Our Session By The Numbers

I played 250 spins on Jawbreaker on iSoftBet’s test server prior to release to test the game. This is what happened.

  • Stake Size: 1
  • Start balance: 1,000
  • End balance: 872.75
  • Hit Rate: 18.4% (46 winning spins in 250)
  • Biggest Win: 11.25x
  • Free Spins Round: 0

We might want to re-name this as ‘balance breaker’. That test session showed all the hallmarks of a ruthlessly volatile slot (though without the winning streak!!). The first 35 spins produced just one (yes, ONE) winning spin. Thereafter things did improve so that overall I finished with an 18.4% win rate (low, but not terrible) but the message is clear – this can be a very streaky game with long low spells.

Jawbreaker Slot Gumball Machine
4 gumballs in the meter but not quite enough for free spins

It took 120 spins before I even saw a Jawbreaker multiplier, then 3 spins in quick succession brought up 3, 2, and 2, with wins of 11.25x, 11,25x and 6x. The best run of tumbles I got was 4 in a row, so the gumball machine never filled up completely. And I never got a sniff of 3 BONUS symbols on one spin. So, no free spins!

Overall, a tough session. No doubt this game will go off from time to time – the free spins round configuration tells you that – but not today.

What We Liked

  • Cool gumball machine feature to unlock free spins
  • Up to 3 Jawbreaker multipliers per spin

What Our Reviewer Says ...

"A clever slot but one for the dedicated high volatility players out there. Filling the gumball machine and waiting for jawbreakers can be a thankless task on many occasions!"

Overall Score: 7.4

Theme & Design

Our Score 7

A Simple Design With Memorable Teeth, Lips and Jawbreaker Logo

Jawbreaker takes its name from the rock-hard sweets that stay in your mouth for hours as layer upon layer of tough sweetness is worn away. iSoftBet have built the jawbreaker into the games logo, merging it with a big set of teeth and lips to nice effect. It appears to be crashing though glass in the multi-colored backdrop to this game. It’s a cool image. You’ll also see a gumball machine to the right of the reels which themselves are stacked with jellies and boiled sweets. Simple, fun artwork. Just what’s needed for a sweet-themed game.

RTP and Variance

Our Score 7

What is RTP?

RTP (Return to Player) refers to the amount a game will pay out in cash prizes expressed as a percentage of all the money wagered on that game. For example, a 96% RTP means a game will pay out £96 for every £100 wagered. This is an average number and will vary from one session to the next.  Read more here.

What is Variance?

Variance refers to how far a game will deviate from its RTP over time. High variance games deviate a lot and produce uneven win distributions and unexpected windfalls. Low variance games provide a more stable and even distribution of wins. Read more here.

Jawbreaker comes with 3 RTP rates – 96%, 93.99% and 92%. Which you play at will depend on your casino operator. Many slot sites in the UK choose lower than 96% so it’s worth checking on the game info screen before you spend your money.

Wherever you play this is a high variance game and our 250 spin test session certainly confirmed that. Wins are likely to be very streaky, and that means possible long spells with little or no return. But of course, the game is configured to go off in a big way from time to time too. Patience and bankroll management are required!

Maximum Win

Our Score 8

What Is Maximum Win?

Maximum win refers to the maximum amount a player can win from one spin. It is expressed as a multiple of the stake. For example, where the maximum win is 100,000x, from a £1 stake, the maximum win would be £100,000.  

The game has a max payout of 10,000x per spin. That’s not bad, and probably about average for a high variance game these days. If you like chasing down slots with lots of potential then check out our list of games with the highest max wins.


Symbols and Paytable

Our Score 7

The game plays on 6 reels, each with 5 rows, and uses the Scatter Pays mechanic. That means you must land 8 or more identical symbols ANYWHERE on the grid to trigger a win.

Jawbreaker Paytable
The paytable with 25x for 12 or more top paying premiums

There are 9 standard pay symbols in the table. They are jelly sweets in yellow, green, blue, purple and red; hard sweets in green, blue and purple and white; and a wrapped up sweet in red with white stars. These are valued at from 0.25x for 8 yellow jellies up to 25x for 12 or more top paying wrapper sweets.

There are NO wilds in this game.

Features and Gameplay

Our Score 8

Jawbreaker is a simple slot with one mission – fill the gumball meter or collect bonus symbols to unlock the free spins round. This is how it works:

Jawbreaker Symbols

Firstly, look out of the jawbreaker symbols, represented by the round white sweet. These carry multipliers of up to 5x. These multipliers are applied to any win on the same spin, and if more than one is involved, they are added together before being applied.

Tumble Wins and the Gumball Meter

A common feature in scatter pays games, tumble wins occur on all winning spins. Winning symbols are removed from the grid and remaining ones, and new ones, drop in to fill the spaces left behind.

If more wins are created, the process repeats. And again, and again, until there are no more wins.

At the same time, with each tumble a gumball is dropped into the gumball meter. If you fill it with 6 gumballs (i.e. 6 consecutive tumbles) then the free spins round will trigger.

And to help you, there is a special feature called Sugar Rush. It triggers at random, adding between 1 and 6 extra gumballs to the meter.

Free Spins Round

As well as using the Gumball Meter to trigger free spins, you can also trigger it by landing 3, 4, 5 or 6 BONUS symbols to get yourself 10, 12, 15 or 20 free plays.

The round is nicely configured to set up some good cumulative wins.

Firstly, not only do jawbreaker multipliers apply to the spin they land on, but they are also collected in a Jawbreaker meter. The current total of the meter is always applied to wins during the round.

Secondly, watch layers be removed from the Jawbreaker meter each time a multiplier lands on a spin. There are FIVE layers, and once each has been removed you reach the core of the sweet where 3 more spins are added to your total. That’s a neat trick!

The Final Verdict

This is a great slot that has been well thought-through. The gumball meter and the jawbreaker feature from free spins are brilliant, weaving the gameplay and theme together nicely. And it feels like you could see some really big moments in that bonus round. Just beware of the volatility, as it might break you if you’re not too careful!

Useful Tips When Playing Jawbreaker

Remember, online slots are games of chance, there is NO strategy that can improve your odds of winning. However, reading our review and following these tips will help you get the most out of your time playing this slot game.

1. Watch For Jawbreaker Multipliers

These are powerful symbols. As many as 3 with values up to 5x can land on one spin. That’s up to 15x multiplier for your wins!

2. Keep An Eye On The Gumball Machine

This is a fun alternative way to unlock free spins! You need to hit 6 tumbles in a row to fill the machine. It’s tough, but it can be done.

3. Check The RTP Before You Play

Remember to check the RTP before you spend your money. Some slot sites may be running this game at just 92%. You want to avoid those!


4. Play At Our Recommended Slot Sites

We have chosen the sites on this page because they all scored high in our reviews and they are licensed by the UK Gambling Commission. That makes them fair and safe places to play slots.
