98%+ RTP Slots Challenge!

So having taken a bit of a battering (within budget...) on "max RTP" 96% games lately, I thought I'd change things up as a slot player for the month of July, and keep a little per-session record on here to see what happens.

As the title of the thread implies, for one month starting 27/06/25 I will not play any slots with an RTP of below 98%. Effectively this means restriction to Slots Temple's 99% RTP Netents, Book Of 99, and Stake's Enhanced RTP Pragmatic titles.

Rules will be: bank doubled = must cash out and stop for the day. No redepositing on the same day if bankroll busts out. Can also cash out if had enough or just feel like it.

Wish me luck? 🫡
 
Have they got money cart?
 
Jokerizer, although for the 98% you can never cashout the base wins, always have to roll them into the jokerizer mode until you win 1000 2000 or 6000.

Smartsoft have a bunch of 98%, not sure if available in UK.

Marching legions is another 98% but is fairly repetitive and the bonus is only attainable after a war of attrition collecting the wild reels (hundreds of them).

Not sure if you will have amatics either but they have a few 98.11%, 97.99 and 97.87%

Fruity Beats Xtreme! by Spinmatic is 99.08%

I'm sure you are familiar with 1429 but avoided it due to low volatility, 98.6%
 
Brilliant suggestions thank you.
 

The thing with Marching Legions is you're sort of 'forced' to do ~3000 spins (IIRC it was around that) to get your bonus, which can and will do a zero pay on occasion.

As such the sheer weight of numbers required, and the volatility of the bonus, means that even with its 98% RTP it can do a bit more damage than you might expect.

Definitely one to just stick on infinite autoplay with a 100x stop trigger or similar (which it rarely hits in the basegame) and wait to see what the bonus does.
 
Good Luck

DoA 98% at L&L seems to give a good value for deposit session most times too,

Keep us posted.

I just played the 98% version on 18p.

Not a single feature in an hour and a half and took £60 off me!!

Nearly 350x without a feature on a not mega hard to bonus game on top RTP.

Just goes to show how easy it is to get fucked over these days.

Yep, exactly why I only ever played it at places I knew wouldn't gub me before I was able to finish it with multiple deposit offers. As a result of that, didn't play it too often.

Dunno why you bothered dude. With the way you seem to run, they could put out an exclusive version just for PMKFRUITPRO running at 118.8% and we'd still be reading endless horror stories beyond our comprehension. :(
 
Tbf it was a winning session overall just that game took the absolute piss. Just felt like it was never gonna bonus so I bailed.

Talking of games which I can barely bonus these days…….

Buff king Megaways and madam destiny Megaways.

With the enhanced feature chance on I’m running so bad. On all sites. Appalling frequency. Over tens of thousands of spins. Often going 3-400 x to trigger. Beginning to think pragmatic have had the spanner out on this ‘double’ chance of a feature. Twice I’ve gone over 500x to trigger a feature with it turned on in the last week. Utter bullshit

We all know RTP goes out the window when that dreaded DOOM switch is turned on, No matter what game, what stake, its all one way traffic once the switch is hit.

What is the switch of DOOM?

If you know you know.

And if you gamble online you will have experienced the DOOM switch. :laugh:
 
I’ve managed to max BK Megaways twice (once with extra bet and once without), so I’m reasonably familiar with the game. You are correct in terms of it being significantly harder to bonus these days. Gotta love the nerfing of what were good games!
 
I will be punting the 98% enhanced versions of both those games (well, standard buff king anyway) in this little exercise so let's see how that goes.

Have tried them previously and it does appear the bases are untouched with slightly better bonus results. So still up against the issue of actually landing the darn scatters. Which can be a big problem on the Pragmatics, as we know.
 
Update if anyone cares. Although I haven't been keeping meticulous records in a whirl of spins, vape clouds and adrenaline - I can summarise how things have gone.

Book of 99 has been consistently awful, regularly costing about 130x for a feature build. Got nowhere near 99% RTP.

Similar batterings were handed out by Fruit Shop, Twin Spin and Butterfly over at Slots Temple. Butterfly Staxx I think I must have had rose tinted memories of as it seems like a consistently awful game with a dreadful mechanic, even on 99% RTP.

Don't get me started on Stake - the 98% Pragmatics sucked like a vacuum cleaner - the clones of Madame Destiny Megaways, Big Bass Boxing and Gates all horrible.

The redeeming slot so far has been Slushie Party which has consistently paid out whopper bonuses and has covered the losses on the other games... Phew.

@slot_zombie I was going to ask you how your experiment is going. It’s interesting to hear that Slushie was paying well. Having had some very good hits on Fruit Party in the past, I was very keen to play Slushie a lot. But I’ve never got anything of note on it, and I find the lower paying symbols harder to tell apart at quick glance. So I gave up on it.

I’m about to commence a session so I must have to give it another chance.

EDIT: Ooh and I forgot to add: I dare you to repeat this exercise on Hacksaws haha…

Book Of 99 never impressed me TBH, you basically get an extra feature every so often with the book collection which is nice and all, it's basically a feature guarantee, but it's just a normal feature so it can and will pay completely wank. It doesn't in any way stop a session from being a shitter.

Twin Spin 98% used to be over at Unibet and I played it a fair bit, remember that the original proper version of Twin Spin was (IIRC) 96.5% so it's not a massive boost to RTP, and I always wondered where they'd put the extra RTP, after all if it was just a handful of rare bigger pays then you could go a lot of sessions without seeing any notable difference.

My experience with playing the 98% slots over at Unibet (back when they were still a thing) was that you'd definitely choose them where available, but they weren't any kind of magic bullet and ultimately of course, you'd still lose all your money given enough time, just at a slower rate on average.
 
Yeah that's my experience too. You'd think you'd get much longer playtime with a halved house edge, and mathematically you should - but that doesn't seem to the case most of the time. Small sample size and all that, but you're still playing against a lot of RTP held back for the big wins and you still need a hefty amount of luck on your side.
 
Despite that whopper of a wild line I hit recently on DoA 98%, I have to say, it can still hand out arse spankings like the 96% and 94% versions.

Play time is improved but not every session, no expert but seems the extra RTP in this game is more appearance of 4OAK premiums in the base game.

Yeah Slushie Party is a great game. I just got a rare retrigger bonus and it paid a satisfactory 175x, which more than tripled my spend on it.
 
I just want to say that I support this initiative! It genuinely upsets me when I think of all the poor sods who are, right now, pissing away their money on 80% RTP slots at the local tribal, and that's the direction things are heading online. Screw that! Win a shit ton of cash zombie et al!
 
Tôi đang chơi như vậy nhưng vẫn chưa đạt được kết quả tốt

Well sadly the results are in on this and I'm wrapping up the challenge early for the simple reason that my monthly slots max budget of £600 has been swallowed up in short order,, about 50/50 to Slots Temple and Stake. If anything play time was less than normal as I can normally get through to the last week of the month playing 2-3 days a week. Sometimes even in profit.

With the sole exception of Big Bass Boxing, which I played to enter the Casinomeister draw, and won $70, I stuck to the 98% slots on about 40p/40 cents. Notable annoyances included a comatose Fruit Shop, Big Bass Boom going 530 spins without landing the bonus and Madame Mystique refusing to bonus at all despite having extra bet on. Slushie Party heroically tried to hold up the balance initially but eventually fell back into line with the rest.

Of course 98%+ slots should still be better than the alternatives but as I commented before, you still really need luck on your side due to the HV in the case of the Pragmatic slots, or the less than ideal maths design of some of the NetEnts. So, the nirvana of wins dropping like rain and doubled play time didn't exactly happen. With infinite money I'm sure you'll see that 98% but I'd estimate mine was around the 70% mark.

So there we go... Bugger.
 
I guess the game to use as a reference point here is full pay Jacks Or Better Video Poker, this has an RTP of 99.54% when played with perfect strategy and its top pay is 800x.

This paytable is for a 50p hand, so the top pay there is £400, i.e. 800x. Then the rest of the paytable is 50x, 25x, and so on, all the way down to 1x for Jacks Or Better.

You'd almost think you couldn't lose on this game, after all, we can win on slots with ~95% RTP and far higher volatilities than this, so how far wrong can it go at 99.54% with nothing more than four 800x wins having to be accounted for in that RTP?

The answer is pretty far wrong!

Once in a while I'll set myself the task of getting a Royal Flush on this game at 3Dice, this has an autoplayer that plays verified perfect strategy so returns that full 99.54%.

Often times it will hold a balance steady for a long time (kind of as you'd expect), sometimes it'll chuck in a Royal sooner rather than later for a nice raise, but once in a while it'll just go on a bit of a rampage and eat through £100-£200 on 50p hands far quicker than you'd expect would be possible on such a low volatility game with an RTP of 99.54%, but of course that's just because I'm getting a bad run on the hands. Nothing sinister going on, sometimes random luck just runs badly for us.

Last time I got my lifetime stats on this game from 3Dice I was basically at RTP so long term it will do that 99.54%, but you can definitely have some rocky sessions along the way.

98% slots will be capable of exactly the same thing of course, and they have a 2% house edge instead of just 0.46%! (And far higher volatility.)

It's not nothing though, 98% slots will, over enough time, take half as much money off you as 96% slots. I personally have some suspicions about how they do the RTP bumps on the 98% slots though, especially NetEnt. I played them quite a lot at Unibet when they had them and it felt to me like the extra RTP was in rarer bigger wins that if you never hit them, could basically just 'vanish' from your expected higher returns.

Again, given a large enough sample size 98% would work out better than 96% of course, but session to session, it could easily make no difference, which is very much what slot_zombie seems to have experienced.

Which is what I said originally when you first started banging on about the 2% drop AND flamed me about it LOL

I don't recall the specifics of the original thread (I guess it's still around but will be hard to find!) but my line at the time IIRC was very much that the 2% loss of RTP absolutely will hurt you as a player over time, with short term fluctuations to be expected.

It was a fair few years ago now though :)
 
I didn't keep a record as you have done but I was playing with my usual stake of 50p (or 60p when not available) on book99 on slotstemple. It was such a miserable experience I did a google search to see if anyone else went through the same thing.

As you imply, it could still be 99% and for that to be the case there must be the occasional big win. I was about 1.5 hours constantly hitting the spacebar losing around £200. I suspect to appreciate the 99% on a machine of such high volatilty, you need to play with a much lower stake than usual. Not sure I can be bothered to try.

Correct. "On paper" mathematically at 99% RTP you should be able to play for hours if not days on a sensible stake to balance ratio. However... Quelle surprise.. I've found that this is never the case.
 
Presumably the UKGC ensures (somehow) that the quoted RTP figures are correct. Anyone know the details of that?

Also, looking at the difference between a 98% and 99% is it true that _in the long run_ your money lasts twice as long in the second slot because 2 is twice 1 (the house edge). OR is it only about 1/98 better because its payout is only 1% better?

Yes, twice as long - ALWAYS take note of the difference between RTP figure quoted and 100. If that doubles, then your average playtime over the distance will halve i.e. if RTP went down 96 to 92% the 4% house edge doubles then your money lasts half as long.

If you check the old spin calculator below you can enter varying stakes and RTP figures and it tells you on average how many spins you will get for 100 credits:
