How do they lower RTP

[kg2025]

What do providers do to a game to lower the RTP from a 96% to 94 % on a different sites. Less wilds , less bonus symbols, more lower pay symbols ???

 

[Reelsoffun]

Its a bit more complex than that and will depend on game and provider but yes basically there is small changes that make a lower RTP, can be anything from a single scatter removal to different symbols or any other variables.

for slots that use a mathematic model, they'll need to create a new one.
for slots that use a fixed number of outcomes ("balls in a bag"), they'll only need to adjust the distribution of outcomes to hit their target number (number of outcomes / total winnings in "x" form = RTP %)

Yes, without intrinsically changing the game i.e. pays for certain O-A-K wins they can simply add more '0' values to the pool or maybe take away some for certain outcomes like say 2x stake wins, reducing their frequency. One simple one is the IGT Cleopatra game in land-based where the 95% online was reduced by simply removing the 2x bet pay for two scatters.

That though is a bit crass IMO, the best way to make it least noticeable is reduce from the top end pays which the average player wouldn't get very often anyway, but carry a sizeable overall contribution to long-term RTP.

What does O A K mean ? Thanks for the replies

Only really noticed the obvious change on Book of Dead. But definitely one less scatter on final reel of 94% version. And barely got any teases the one time I accidently played the 91% version, so must've removed more.

A very simple way to lower RTP, though surely bonus frequency would drop significantly and player would lose interest.

I still seemed to get decent base game hits when playing lower RTP version, but then always play 1 line. So would be difficult to know if they're less frequent, bearing in mind most spins are losses.

I think it was trancemonkey that said that most providers aim to keep the basegame as close as possible to the max rtp version, which makes sense because it takes players a lot longer to notice that they are playing a gimped version if the basegame plays the same.
Having a bad run with many spins between bonuses happens even on 96%+ slots.

As important as rtp is, i think it is even more important how it is distributed.
Imo many Novomatic slots deliver a better experience than a lot of 96%+ rtp slots do even tho they have 1-2% less rtp.

Whoops, just realised my equation had them the wrong way round winnings in x / number of outcomes

Really interesting replies here, even for me, thank you all

You can just make another set of maths and remove a couple of wild/bonus symbols from the base reels so the total RTP is say 80%. Then on every spin do a weighted decision between using the reels for the 96% or 80% maths. 75/25 gives you 92%, 50/50 gives you 88% and so on.

If you need a bigger range of RTP's all you've got to do is change the two weighting numbers and you can make the game return whatever you like between 96 and 80.

Purely going by the title of this thread, this is how I imagine the RTP of a slot is lowered.

 

[mulven]

Another example of a simple change is the slot "triple bar slot". The 98% version pays 40x on gold symbols and the 96% pays 36x

The balls in the bag is best way to think about it, If they had 100 balls and 51 win balls and 49 lose balls today, tomorrow they might have 41 win balls and 59 lose balls. In essence every slot is just win or lose if you play Videoslots battles and use supersonic spins on Raw then that's all a slot is, dip your hand in the bag and it picks a win or lose.

Though I would like to know how they choose what amount you win and whether you get a bonus.

Would each ball drawn not only indicate a winning spin, but also a winning amount or bonus trigger with winning bonus amount?

The 'bonus bag' is simply one of two things - it's a result in the same spin general RNG bag, represented by trigger scatters and giving a predetermined amount (i.e. Push Gaming's Jammin' Jars) or a separate 'bag' with a fixed total RTP.

By that, say 20% of the game's 96% is contained in a separate bag which you enter by 3 scatters (paying either x-times-stake or a zero result from the first bag) then you draw free games without predermined results and with separate RNG pulls. This bag pays a RTP of 100% of the 20% long-term RTP allocated to its RNG selection and has different results balls/graphics.

So when triggering bonuses, player A can get 5x bet and player B gets 2453x bet but over time all bonuses won will pay the 20% of total RTP they are assigned.

Sorry @steveh35 I just realised I answered the wrong question, back to school exams for me lol....

You weren't referring to slot bonuses d'oh!!

The ball example works well for a simple dice game in crypto sites.

For example if you play a simple 2x win with no house edge (100%RTP) then if you roll Under, balls 1 - 50 win, balls 51 to 100 lose. Vice versa for Over.

But if the house edge is 2% (98% RTP) Then ball 50 turns into a losing ball for Under, ball 51 turns into losing ball for Over

but slots very interesting because its various combis.
