Lil Devil slot review

What the Lil Devil slot is

Lil Devil is a Big Time Gaming slot from 2019 that swaps the studio’s famous changing reels for a fixed 6×4 grid. Every spin shows 24 symbols, and wins pay left to right on adjacent reels, so there are always 4,096 ways to win: four positions on each of six reels, multiplied together.

Big Time Gaming was founded in Sydney in 2011, is led by Nik Robinson and became part of Evolution after a deal announced in April 2021. It is best known for the Megaways mechanic, seen in games like Bonanza Megaways. Our Big Time Gaming page lists more of its slots. For the full set of reviews, start at our slots hub.

How the features work in Lil Devil

Multiplier wilds in the base game

The middle reels can land wilds: a Devil Wild and Angel Wilds. These carry multipliers between 4x and 12x, which are applied to wins they help to form. Because the multiplier sits on the wild itself, one well-placed wild can turn a small line of matching symbols into a far larger return.

Choosing your free spins

Land three or more Wooden Hut scatters and the game asks you to choose a round. Be My Angel free spins let you pick a symbol that becomes sticky wilds, and any reel that fills completely turns into Angel Wilds. Dynamite Lover free spins use cascading reactions, where winning symbols are cleared and replaced, plus a Dynamite Wild whose multiplier grows as the round goes on.

The heart meter

Landing two scatters in the base game doesn’t trigger the bonus, but it does award hearts. Collect 40 hearts and enhanced versions of both free spins rounds open. The game rules explain what the enhancements add and whether the meter’s progress carries over, so read them before you rely on it.

4,096 ways explained: the maths behind the grid

Ways-to-win slots pay for matching symbols on adjacent reels starting from the left, regardless of row. On a grid with four rows, each reel offers four positions, so the count is 4 × 4 × 4 × 4 × 4 × 4 = 4,096.

That doesn’t mean 4,096 separate bets. You pay one stake per spin, and the game checks every path at once. More ways tend to mean more frequent small wins than a 10-line game, but the RTP and volatility, not the ways count, decide what the game returns over time.

Our guide to Megaways slots on mobile shows how changing reel heights push the count far higher, and why a bigger number doesn’t mean a better game.

Lil Devil RTP and volatility: how far £20 goes

At 96.43%, Lil Devil’s house edge is 3.57%. One useful way to picture that is to ask how much you’d need to stake, on average, before the expected loss reaches £20: £20 ÷ 0.0357 = about £560.

Treat the middle columns as a best-case average, not a forecast. High volatility means a £20 balance can run out long before that, especially at £1, where the last column shows just 20 paid spins unless something lands. Equally, a strong bonus can run a balance up. The edge only describes the long run.

The published specification for Lil Devil doesn’t include a maximum win, so we don’t quote one. If a top prize matters to you, the figure is in the game’s rules screen.

Playing the Lil Devil slot on your phone

Lil Devil runs inside the casino app’s game window on iPhone and Android whenever the operator lists it. A 6×4 grid is wider than a classic 5×3 slot, and its specification doesn’t say whether there’s a portrait layout, so try turning your phone to landscape if the symbols look small. Our guide to landscape vs portrait mode explains the trade-offs.

1. Find Lil Devil in the app’s lobby by searching its name.
2. Open the rules or “i” screen and confirm the RTP your app shows.
3. Read how the heart meter works in that version.
4. Pick a stake that gives your budget enough spins for a high-volatility game.
5. When the scatters land, choose the free spins round you prefer.

Lil Devil and the UK’s online slot rules

All UK-licensed apps apply the same slot rules to Lil Devil, so the game will feel the same whether you play at a casino-only app or a sportsbook app with a casino tab.

The Gambling Commission’s RTS 14 responsible product design standard (opens in a new tab) sets out the speed and celebration rules. Since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players. The Commission’s online slots stake limit guidance (opens in a new tab) explains how the £5 and £2 caps apply to each game cycle, and our game speed rules page has the detail on timing.
