The Lil Devil slot is a 2019 Big Time Gaming release with a 96.43% RTP, high volatility and 4,096 ways to win on six reels. Its standout idea is choice: three scatters let you pick between two very different free spins rounds, and a hearts meter upgrades both. Here's how each part works and what it costs.
Big Time Gaming lists a 96.43% RTP, an average cost of about £3.57 per £100 staked.
Six reels of four rows give 4 × 4 × 4 × 4 × 4 × 4 = 4,096 ways to win.
Wilds on the middle reels carry multipliers of 4x to 12x, according to the game's description.
You choose between a sticky-wild round and a cascading round; 40 hearts upgrade both.

What the Lil Devil slot is
Lil Devil is a six-reel game from Big Time Gaming, the Sydney studio best known for inventing Megaways. It isn't a Megaways game, though. The grid stays fixed at four rows, and the interest comes from multiplier wilds, a pick-your-bonus screen and a collection meter that carries progress towards stronger rounds.
Big Time Gaming was founded in 2011 and has been part of Evolution since a deal announced in April 2021. The specifications below are the published figures as recorded in our checked slot data.

How 4,096 ways to win are counted
With ways to win, there are no fixed lines. A win needs matching symbols on adjacent reels, starting from the left, in any row. Each reel has four positions, so the number of possible paths is four multiplied by itself six times.

More ways doesn't mean a better return. The RTP is fixed at 96.43% whatever the grid, so more ways usually means each individual way pays less. Our comparison of Megaways and classic slots explains how layouts trade frequency for size.
How the features work in Lil Devil
Multiplier wilds on the middle reels
In the base game a Devil Wild and Angel Wilds can appear on the middle reels. The game's description gives these wilds multipliers of between 4x and 12x. As a simple example, a combination worth £1 that runs through a 4x wild would pay £4, and through a 12x wild it would pay £12. How several multipliers combine on one way is set out in the paytable, so check the help screen.
The Wooden Hut scatters and the bonus choice
Three or more Wooden Hut scatters take you to a choice screen. Instead of one fixed bonus, you pick one of two rounds with different mechanics.
Be My Angel free spins
In this round a chosen symbol turns into sticky wilds, which stay in place for the rest of the round, and any reel that fills completely turns into Angel Wilds. The appeal is that wilds build up as the round goes on. Our page on sticky wilds shows how this type of feature works elsewhere.
Dynamite Lover free spins
This round uses cascading reactions: winning symbols clear and new ones fall into the gaps, so one spin can pay several times. A Dynamite Wild carries a multiplier that grows during the round. See cascading reels for the general mechanic.
The hearts meter
Landing two scatters in the base game, one short of a trigger, awards hearts. Collect 40 and you get access to enhanced versions of both free spins rounds. The game's description doesn't confirm whether hearts are saved between sessions, so check the help screen before counting on a part-filled meter. The OLBG Lil Devil review (opens in a new tab) describes the same two-round choice.
Which Lil Devil bonus should you pick?
The choice is about how you want the round to feel, not about getting more back. The developer doesn't publish a separate RTP for each round, and the overall 96.43% already includes both. Picking one round over the other won't make the game cheaper to play.

Lil Devil RTP and the real cost per spin
A 96.43% RTP leaves an average cost of 3.57% of everything you stake. At 50p a spin that's about 1.8p a spin on average. The table puts it in hourly terms, assuming 500 spins an hour, which fits within the UK minimum of 2.5 seconds per spin.

These are averages over enormous numbers of spins. In any one hour you could lose much more than the table shows, or finish ahead. The house edge simply means losses are the likely result over time. See theoretical loss for the formula casinos use.
What a £20 budget looks like at 10p, 50p and £1
On £20 staked once through, the average loss is about 71p (£20 × 3.57%) at any stake. Volatility decides how that plays out. High-volatility games like this one hold back a lot of their return for the bonus rounds, so the number of spins you can afford matters.
10p a spin: 200 spins. The best chance of seeing a bonus choice screen on £20, though even 200 spins carry no promise of one.
50p a spin: 40 spins. A dry patch of that length is ordinary on a high-volatility slot.
£1 a spin: 20 spins. Over this short a run the result is close to a coin toss on whether anything notable happens.

Lil Devil max win: what we can and can't confirm
Our checked data doesn't include a verified maximum win for Lil Devil, so we won't quote one. Figures circulate online, but without a developer source we can't confirm them. The in-game help screen at your casino states the cap for the version you're playing.
What we can say is how a cap translates: a win shown as a multiple of stake scales with your bet, so the same multiple at £1 is ten times what it is at 10p. Our explainer on the highest-paying slots explains why the biggest caps also tend to come with the most volatile play.
How to play Lil Devil online in the UK
Sign up at a UK-licensed casino and complete age and identity checks.
Open Lil Devil and read the help screen for the RTP, stake range and max win.
Set your stake; all 4,096 ways are active on every spin.
Spin manually, since UK slots have no autoplay.
Look out for multiplier wilds on the middle reels.
When three or more Wooden Hut scatters land, choose Be My Angel or Dynamite Lover.
Track the hearts meter if you want the enhanced rounds, but don't raise stakes to fill it.
Stop at your planned limit and check the net spend shown on screen.
UK rules that apply to Lil Devil
At UK-licensed casinos, slot stake limits cap a spin at £5 for players aged 25 and over and £2 for those aged 18 to 24, as the Gambling Commission's stake limit guidance (opens in a new tab) explains. Since 31 October 2021, online slots must run at least 2.5 seconds per spin, can't offer autoplay, turbo or slam-stop, and must not celebrate a return equal to or below your stake.
Danger High Voltage is the closest relative, with the same studio and the same 4,096-way grid, though its own bonus details differ, so read its review before assuming the two play alike. For fiery themes, see our Halloween slots collection.

Frequently asked questions
What is the RTP of Lil Devil?
Lil Devil has a published RTP of 96.43%. Over a very long run of spins, that returns £96.43 for every £100 staked, leaving an average cost of £3.57 per £100. Because the game is highly volatile, a short session can finish a long way from that figure in either direction. Check the help screen in case your casino runs a different version. Our RTP explainer shows how the number is set.
Who makes Lil Devil?
Lil Devil is made by Big Time Gaming, the Australian studio founded in 2011 and best known for creating the Megaways mechanic. It was released in 2019 and has been part of Evolution's group since a deal announced in April 2021. Lil Devil itself uses a fixed six-by-four grid rather than Megaways. See our Big Time Gaming page for the studio's other games.
How many ways to win does Lil Devil have?
Lil Devil has 4,096 ways to win. The grid is six reels with four rows each, and four multiplied by itself six times is 4,096. Matching symbols on adjacent reels from the left pay, in any row, so there are no fixed lines to choose. More ways don't raise the RTP; it stays at 96.43%. Our ways to win guide explains the counting.
How do you get the enhanced bonus rounds in Lil Devil?
You get the enhanced bonus rounds in Lil Devil by collecting 40 hearts. Hearts are awarded when two scatters land in the base game, and a full meter upgrades both the Be My Angel and Dynamite Lover rounds. Check the help screen to see whether progress is kept between sessions. Never raise your stake just to fill the meter faster; our chasing losses page explains why.
Which free spins round is better in Lil Devil?
Neither free spins round in Lil Devil is published as better, because the developer gives a single 96.43% RTP for the whole game. Be My Angel builds sticky wilds over the round, while Dynamite Lover uses cascades and a growing multiplier wild. The choice changes how the round plays, not its average value. Our bonus rounds page covers pick-style features in more depth.
Can you buy the bonus in Lil Devil in the UK?
No, you can't buy the bonus in Lil Devil at a UK-licensed casino. Since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players, so the free spins can only be reached by landing scatters. Some versions outside Great Britain may differ. Read our page on buying bonus rounds on UK slots for the background.
What is the max win on Lil Devil?
We haven't been able to verify a maximum win for Lil Devil from a developer source, so we don't quote a figure. The cap for the version you're playing is shown in the game's help screen. Whatever the cap, it scales with stake, and in Great Britain stakes are limited to £5 a spin, or £2 for players aged 18 to 24. See what a slot's max win means.
Is Lil Devil a high volatility slot?
Yes, Lil Devil is rated high volatility. A large share of its return comes from the free spins and multiplier wilds, so base-game wins tend to be modest and long dry spells are normal. That suits players who accept bigger swings on a fixed budget, and it means short sessions often end with a loss. Our list of high-volatility slots has other examples.
