Lil' Devil Technical Analysis - Best Symbol on Be My Angel & Heartstopper etc

[The Reel Story]

Ola everyone! For anyone who has seen my thread about Danger! High Voltage (Danger! High Voltage - Technical Analysis (The best symbol on Gates of Hell and other info)) you'll probably know what this is about.

I decided to try and dig into the new BTG slot 'Lil' Devil' and find out a bit more about it.

I've focused on the 'Be My Angel' bonus, which is the 'enhanced' version of Gates of Hell from DHV. The other bonus doesn't really have any interesting information in it.

So I wanted to find out the best symbol in Be My Angel, how the 'Heartstopper' version differed and also, how it compared to DHV.

First thing I noticed is that you don't appear to be able to get the Heart as the symbol (like you could get Skulls on Gates). This is good, because skulls were horrible. This means that, on average, you *should* get better bonuses (or less duds) than on Gates. This is probably offset by the fact that bonuses seem to be rarer in Lil' Devil than they are on Danger.

Below is a table ranking the symbols from best to worst. It's a different mix to that of Danger, and most notably all of the premiums are pretty bad (whereas Taco on DHV was 3rd best). The other thing to note is that the best symbol, 9's, are best by a long way, and better than anything in DHV. The other symbols are broadly similar.

Symbol	Frequency	Reel 2	Reel 3	Reel 4	Reel 5
Nine	44	10	14	12	8
Ten	38	10	16	8	4
Queen	36	11	14	7	4
Jack	36	9	13	10	4
Ace	34	7	10	12	5
King	32	6	13	8	5
Croc	31	11	11	7	2
Scorpion	29	11	10	6	2
Lizard	29	8	13	4	4

Ok, so now on to Heartstopper. What I've seen in most comments is 'Heartstopper Angel is like gates but with 2 symbols! OMFG THAT'S SO AMAZING'. Reality? It's barely better. In fact, what I've found would probably make me go with the other bonus for my Heartstopper. There is probably more potential in Angel, but it's really not that great.

So as you can see below, getting 9's in Heartstopper Angel is only 2 symbols better than getting 9's in Non Heartstopper. The only major benefit is the symbols are weighted towards the middle reels, so higher chances of re-triggers with those lovely growing multipliers. Overall though, you're only getting a few extra symbols that can become wild. The main thing it does is balance out all the bad symbols. So even if you get the worst combination (two premiums) it's still the same as an good symbol in regular Angel. Is that worth grinding 40 hearts? Not in my opinion.

Table below shows the Heartstopper Angel frequencies. As you can see, it's really not the 'OMFG' bonus that it is made out to be. If it were me, I'd go with the starting x5 wilds on the other bonus.

Symbol	Frequency	Reel 2	Reel 3	Reel 4	Reel 5
Nine	46	9	15	16	6
Queen	44	10	17	12	5
King	42	11	16	11	4
Jack	42	10	14	14	4
Ace	42	11	13	12	6
Ten	39	7	17	11	4
Croc	38	11	14	10	3
Scorpion	38	8	16	7	7
Lizard	38	11	13	10	4

So yeh, there we go. Shout if you have more questions or things you would like me to look in to!

 

[lotusch]

Thanks man, really good to see the reels for BTG slots stripped down..
The DHV one was good and this one is very helpful too.

 

[PMKFRUITPRO]

Let’s be honest in 9/10 features what ever symbol you get, it goes on bloody holiday.

Yet you always see big clumps of other symbols land. Something that happens once in a blue moon on ur chosen one.

If it’s a genuine random spin from a different reel set then how comes it litters the reels with just the one symbol (not yours) on nearly every bonus!! I’m talking more DHV here rather than this clone.

There has to be something else going on in the background that controls things.

Thanks for the info tho, it’s always an interesting read.

 

[PMKFRUITPRO]

I thought you could get top symbol in the ordinary gates clone feature???? I maybe wrong of course.

 

[PMKFRUITPRO]

I’ve just checked..... you can indeed get the Purple Heart on the ordinary be my angel feature

That's exactly the point. When it chooses a symbol (say 10's), you get switched to the 10 Gates of Hell reel set, where the number of 10's on the reels is vastly reduced (and the numbers of other symbols are changed as well).

I would say that the 'littering with another symbol' is probably more an anecdotal thing that has happened to you and stuck with you than a statistical one. As I say, other symbol numbers are changed, so it could be that another symbol gets increased instances, but not enough to see this happen consistently.

It is also possible there are reel weightings going on behind the scenes as well (no way to tell), but given the reel sets defined and the setups, it feels like this is unlikely.

 

[The Reel Story]

That's interesting. There doesn't appear to be a reel set defined for it (and I've never seen it triggered). I'll have to try and trigger it in fun mode and see what reel set it says it's using. It's possible there is a set that is used twice.

Or maybe it appears 0 times on all reels, and therefore dont need a reel set.

 

[NST]

How do you get this info? Do you just play heaps of features on play mode? And do you count the symbols that actually fly past?

Yes I’ve not seen it triggered either. But as a visual, it’s most definitely on the symbol picking reel, you can see it quite clearly!! However I’ve only seen a handful of bonuses so far, but if it’s something that can’t be achieved then I’m sure BTG aren’t silly enough to allow it.

RE: Your table above, so the numbers you give for say 9’s is the number of 9’s on each strip when you are actually given the 9 symbol? Would be interesting to compare that against the amount of other symbols frequencies to see just how badly gimped the reels become.

Again thanks for the info. Much appreciated.

 

[The Reel Story]

Haha, no. The reel sets for BTG games are defined in the game communications to the server. Just. Copy and paste them, parse into a spreadsheet and analyse.

I agree. It's possible it never lands, but would be odd graphically.

I'll post the base game reel set tomorrow when I'm back at my comp so you can see answer. Pretty gimped!

 

[CasinoNinja]

Now please see if you can find something similar to this with Cazino Cosmos by Yggdrasil @The Reel Story , would be very interesting to see what the chances are to hit a wild during the freespins bonus, and even more intersting during the enhanced features!

I second this, especially curious to know if it would have been possible for reel 5 in this screenshot to land 1 position up for instant wildline with 20 guaranteed wildline spins. Technically it should be possible but I doubt they allow it in the code. Only 500x with this brilliant setup by the way ...

It's rare for developers to disallow specific outcomes. Normally if a game is designed with reel sets, then any combination is possible (Devs like big wins remember, it gives their game loads of publicity. Just look at DOA2).

I'll try to look into it at some point. I've never looked at an Yggdrasil game, so no idea if they publish the reel sets in the communications. If not, then it should be in the game code somewhere, but that could well be obfuscated making it very difficult to find. Sometimes it's not in the client at all, and the server just sends the symbols to display and the reels spinning past are fake, but that tends to be rare on a modern game.

 

[Jono777]

Side note: I am CONVINCED that most game codes will restrict certain positioning of reel set ups, at certain times. Not to do us out of wins but to uphold the TRTP,

Could possibly explain this much better but its something I've believed and always will, whether I'm applauded or laughed off the stage!

 

[IM_SPORTS]

BTG games never pay anything these days
mostly all hype

dead or alive 1 and 2 will always beat any game btg produce
just look at the biggest wins on casumo for last month over 2000x or any month

i bet you doa has like 90 or more 2000x wins and danger higher voltage will have like 7.
they always offer so much you could have a ton of spins left with a screen that looks amazing but then it never produces what it should

That is really just a misunderstanding of what TRTP is and how it works. The point is, the reel sets as defined will SET the TRTP. You don't need to restrict certain combinations because that is already taken into account. If you need to stop it going crazy for whatever reason, you just put a max win cap on it. Restricting specific outcomes is the most complicated method of achieving what you're saying, so would be pretty pointless

Thanks. Maybe it is possible, I've just never seen a screenshot of it, or a video. So as far as I know it never happened. I've had 4 starting wilds with 3 or 4 scatters on several occasions, 2 starting wilds with 5 scatters once but never 5 starting wilds, nor have I ever seen it documented anywhere. So either it's extremely (jackpot like) rare or it's prohibited by code. My best win on this slot, 2251x, was nowhere close to these 'dream' starts so perhaps the reel set you actually get in the free spins is way more important than the starting wilds. Anyway, I would love to know how this slot is coded.

Likely just very very rare. There are often billions of permutations within a slot, and only a handful will do what you're saying, so yeh, we're probably talking lottery win odds

I'll try to take a look at some point in the future if I get some time

 

[trancemonkey]

Haha, no. The reel sets for BTG games are defined in the game communications to the server. Just. Copy and paste them, parse into a spreadsheet and analyse.

This assumes that the reel sets being passed are the ones used to determine the outcome, and not just some "fake" ones used for the visual reel spin

Haha, this is true, but it'd be a joyous feat of overengineering to send these from the server rather than just hold them in the game code

 

[dunover]

LOL...I was playing this on demo today and got the enhanced trigger. Chose the 7 spins, got 9 as the other symbol aside from the heart. Result - 2x stake. 16 positions to get one of two symbols, x 7 spins, equals 112 tiles. I got one 9 on reel 3 on the 4th. spin.

Yep, would have got 6x for the 3-scatters if I had triggered normally. I then went for another enhanced feature, took 1,100 spins to get the next 40 hearts and in the meantime not one 'normal' trigger. This time I got 22.4x.

My bonus on demo-mode ended about the same. 9x stake.
Thing is, i hit a bonus for 1300x while i was filling the hearts.

Not 100% sure what to think about this game.
Ill probably give it a go on 10 or 20p when it comes to all sites.

And yet they could of, quite legally and easily, made the enhanced feature guarantee a minimum of 20x (or some other reasonable value)...

Fine if the normal features are volatile, but at least reward something for the chase of the other one...

Bad maths and design there IMHO

I'd agree with that. Can't imagine it'd have a massive effect on the RTP to offer some kind of bonus guarantee.

 

[VismundCygnus]

I think the RTP contribution for the Heartstopper is quite low.

 

[CertaCas]

So yeh, there we go. Shout if you have more questions or things you would like me to look in to!

First of all, thank you for doing this! After an insane (no really) amount of spins on this slot I have a couple of questions:

1. Can you tell me all of the possible wild combinations on reel 5? Or perhaps just a link to all the reels so I can figure it out myself. Especially interested to know if a wild + purple heart is possible on both reel 2 or reel 5. I expect no, but I want to be sure. Related to that: what is the maximum base game hit with wilds on reel 2 and 5, 12x angel on reel 3 and 4 and the best possible combinations on reel 1 and 6?
2. Does each symbol have a separate reel set for the bonus round? Does it differ from the reel set for the heartstopper bonus?
3. Can you calculate the bonus frequency through the reels? I've had back to back bonuses twice but also not had a bonus for close to 70 hearts, like more than 3 hours of autospin without a bonus. Also had 7 bonuses once within 1 heartstopper round. It all screams extremely high volatility.
4. Your ranking doesn't take symbol pairings into account. What would be interesting to see is not only the frequency of symbols on a reel but their best possible way to land for multiple symbols in view. It's much easier to get a retrigger with paired symbols, frequency isn't everything. Again, having all of the reel sets would help me figure this out myself as well. I know I can't influence it in any way, I'm just interested in the math behind it all.

There is 1 wild symbol on reel 5 and the symbols around it are

0​

9​

6=K
10=9
0=Wild
9=10
8=J

Wild + Purple Heart is not possible on either reel (that I can see). It is possible on Reel 4.

Max base game hit is pretty hard to work out, as you'd need to find all the combinations of possible wins and see if any of the lower symbols at higher ways outpay the bigger symbols at lower ways. DM me an email address and i'll send you the reelsets. You can give it a go if you want

2. Does each symbol have a separate reel set for the bonus round? Does it differ from the reel set for the heartstopper bonus?

There are 21 reel sets in total. Each symbol in 'Be My Angel' has it's own reel set and each has another set for the heartstopper. In total the reel sets are

1 for base game
9 for Be My Angel
9 for Be My Angel Heartstopper
2 for Dynamite Lover (not sure if they are both used during both standard and heartstopper, or if there is one for each. I've not checked)

There are also 2 sets of cascade definitions for use in Dynamite Lover

3. Can you calculate the bonus frequency through the reels? I've had back to back bonuses twice but also not had a bonus for close to 70 hearts, like more than 3 hours of autospin without a bonus. Also had 7 bonuses once within 1 heartstopper round. It all screams extremely high volatility.

If my statistical maths were better, yes... but it's not haha. Scatter frequency on the reels is 3,2,2,2,3,3. this is quite a lot lower than Danger! High Voltage, which has 3,4,3,3,4,3.

4. Your ranking doesn't take symbol pairings into account.

I know I can't influence it in any way, I'm just interested in the math behind it all.

I don't think it makes a difference, as a pair of symbols will be hit less frequently, so it should even out. As above though, my stats isn't great, so I could well be wrong here! Happy to send the reel sets tho, so DM me.

Hi, I thought I'd take a look at the code, I take it comes from the .JS file?

I could only see 18 reelsets though, and how do you know which number refers to the image, say 8 = J

 

[The Reel Story]

Easier if you get it from the game communications rather than dig through the JS.

To identify the symbols, do a spin and look at the game communications, match up the results in the coms to the symbols on the screen. BTG always seem to use the same system as well, so that makes it easier (1 is highest paying, then go in order to lowest paying. Then scatter after that.

I can send you the parsed reel sets if you want them. DM me.

[The Reel Story]

Chrome > Menu > More Tools > Developer Tools

Go to the network tab. All coms in and out of the browser tab will be displayed there. Locate the ones that are the game communications by clearing the list before you load the game, then click on them and check the request and response for the bits that look like game communications (normally JSON or XML).

I could do that if people wanted me too, would need to know how many total symbols per reel too please

Ta i will go work it out now, thats IF what we see its true of course as TBH i wasnt convinced that the DHV reel strips were genuine but i will see what it come out at.

 

[The Reel Story]

I did some tentative testing on the reel strips on this and DHV and the results that landed during spins were always combinations that were on the reel strips, so I believe they are genuine. The main thing we can't tell is if there are any weightings applied. If there are, then we will naturally be inaccurate on any statistical modelling based solely on the strips.

Not usually a gambling man but I'd bet everything I own and ever own in the future that they most certainly are!

 

[Reelsoffun]

Well with the info we have it would come out at a 301 spin feature average, if i done it right, I will check my math later when got more time.

Eg 315 ave for a 3 trigger but overall feature 301 spins ave.

 

[Reelsoffun]

This slot is pure chasing.

I hope the UK Commissions, nip this in the bud

I hope they dont as we would lose games like immortal romance and MANY others, at least with this mechanic the player knows what they getting into from the off and can choose whether to play or not, I never play Yggdrasil chase ones but like this, IR and chilli for example.

That doesn't feel too far out from my (albeit limited) experience with the game.
