What Jokerizer is

Jokerizer is Yggdrasil's retro fruit machine — a 5x3 grid with 10 paylines, deliberately old-fashioned artwork, and the highest return figure in the studio's catalogue at 98.00%.

That figure is real, widely published, and comes with a condition almost nobody mentions.

The 98% is conditional — read this first

How you play	Return	House edge	Cost per $1,000 staked
Jokerizer Mode	98.00%	2.00%	~$20
Base game	96.00%	4.00%	~$40

The base game returns 96.00%. The 98.00% figure applies when playing in Jokerizer Mode, and published descriptions specify it applies when that mode is played optimally.

How Jokerizer Mode works

The mechanic is unusual enough to describe carefully.

After a spin, you can enter Jokerizer Mode by spending accumulated winnings rather than staking fresh money. Published descriptions note that after a non-winning spin, players have the option to spend a defined amount to spin again with significantly increased Joker wild activity on the reels.

Inside the mode, Joker symbols can substitute across the full reel grid with multipliers that amplify connected winning combinations, and mystery bonuses become available.

So the mode is not a bonus round you wait for. It is a state you choose to enter, funded from winnings, that changes both the symbol behaviour and the return percentage.

What the two figures cost

Spins at $0.50	Turnover	Jokerizer Mode (98%)	Base game (96%)	Difference
500	$250	~$5.00	~$10.00	~$5.00
2,000	$1,000	~$20.00	~$40.00	~$20.00
10,000	$5,000	~$100	~$200	~$100

A hundred dollars across five thousand spins, decided entirely by whether you use the mode. On no other game we cover does the player's own behaviour move the return by two full points.

A slot with an actual decision in it

Worth stating plainly, because this site repeatedly points out that slot decisions are usually cosmetic.

Choosing a free spins configuration, picking a chest, deciding which bonus round to buy — on almost every game we cover, those options are calibrated to similar returns and only change the variance. They feel like decisions and they are not.

Jokerizer is different. The mode carries a genuinely higher published return, so entering it is a decision that changes your expected cost rather than just the shape of the distribution.

That does not make the game beatable — 98% is still a house edge, and no sequence of correct decisions turns it positive. It means that on this specific title, playing well and playing badly are different things.

What "played optimally" means

Published sources attach the 98% figure to optimal play of the mode, which is worth being precise about — and honest about where our information runs out.

What is documented: the mode is entered by spending accumulated winnings, the option is offered after spins, and the mode carries higher Joker activity with multipliers.

What is not clearly documented anywhere we found: the exact rule for when entering is correct and when it is not. That is the detail that separates optimal from approximate, and it will be in the game's own rules pages.

The practical guidance: read the rules screen before playing, understand exactly what entering the mode costs and what it changes, and if you are not going to use the mode, understand you are playing a 96.00% game rather than a 98.00% one.

The published numbers

Statistic	Figure
Return in Jokerizer Mode	98.00%
Return in base game	96.00%
Volatility	Medium — though some sources call it highly volatile
Grid	5x3, 10 paylines
Mystery bonus	Reported from 1,000 coins upward
Maximum win	Not verified — read the game panel

Note the volatility row. Yggdrasil's catalogue is described as medium-to-high overall — no tracked title exceeding a volatility rating of 6 — and this game sits in the medium band on most listings. Some describe it as highly volatile, likely reflecting how the mode plays rather than the base game.

Mystery wins

The mode's signature payout is the mystery win: a bonus of unrevealed value, reported at a minimum of 1,000 coins.

Mystery awards are worth understanding as a design device. They convert a known outcome into a two-stage one — you learn that you have won before you learn what you have won — which stretches the moment in the same way a nudge or a reveal animation does.

The value is determined when the award triggers. Nothing about how it is revealed carries information.

98% in context

Game	Studio	Return
Marching Legions	Relax Gaming	98.12%
Jokerizer (in mode)	Yggdrasil	98.00%
Blood Suckers	NetEnt	98.00%
Big Bad Wolf	Quickspin	97.34%
Jokerizer (base game)	Yggdrasil	96.00%

The same game appears at both the top and the bottom of that table. That is the point of this page.

Stake sizing in practice

• Read the rules screen before your first spin and understand exactly what entering the mode costs.
• If you are not going to use the mode, budget as though playing a 96% game — because you are.
• Budget 250 to 300 spins; the medium rating supports a longer session.
• Confirm the active return in the game panel, and check whether it lists both figures.
• Set a time limit as well as a loss limit — a comfortable retro game runs long.

Where this fits in a session

Used properly, Jokerizer is one of the best-priced games available anywhere. A 2% house edge is close to the floor of what commercial slots offer, and it comes with medium volatility rather than the punishment usually attached to high-RTP titles.

Used casually — spinning the base game and ignoring the mode — it is an ordinary 96% slot with dated artwork, and there are better-looking ways to pay that price.

The difference is entirely in whether you read the rules first. Few games on this site reward five minutes of preparation as directly.

Common misconceptions

The first is that the game returns 98% however you play it. The base game is 96.00%.

The second is that a 98% return makes the game beatable. It halves the cost; it does not remove it.

The third is that retro artwork means a simple game. This has the only genuine strategic layer we have documented across 110 titles.

Who this suits

This suits a player willing to read a rules screen and use a mode deliberately, in exchange for one of the lowest house edges in commercial slots.

It suits poorly anyone who wants to press spin and not think — that player is getting 96% and an old-fashioned fruit machine, which is a worse deal than it looks.

FAQ

Conditional returns across this site

Jokerizer is the clearest case, but a published RTP being conditional on how you play is more common than most players realise. Recognising the pattern is worth more than the specifics.

Game	Base return	Conditional return	Condition
Jokerizer	96.00%	98.00%	Jokerizer Mode
Money Train 2	96.40%	98.00%	Bonus buy
Tombstone R.I.P.	96.08%	97.03%	Bonus buy
Misery Mining	96.00%	96.85%	Bonus buy
Hellcatraz	See page	Varies	Mode selection

Jokerizer differs from the rest in one important way: the others reach their higher figure through a bonus buy, which concentrates hundreds of spins into one outcome. Jokerizer's mode does not do that — it changes the symbol behaviour while you continue playing spin by spin.

So the variance penalty attached to every bonus buy on this site does not apply here in the same way. That makes this the most straightforwardly favourable conditional return we have documented.

Reading the rules screen

• Both return figures — whether the panel lists the base game and the mode separately, as it should.
• Exactly what entering Jokerizer Mode costs and how it is funded from winnings.
• When the option to enter is offered — after any spin, or only after specific outcomes.
• What Joker symbols do inside the mode, including multiplier behaviour.
• The mystery win range, reported from 1,000 coins upward.

This is the one game on this site where reading the rules screen has a measurable cash value. Two percentage points is $20 per $1,000 staked, and the information is free.

Retro slots and why some of them return so well

Jokerizer's deliberately old-fashioned presentation is worth a note, because there is a pattern behind it.

Retro-styled fruit machines frequently carry very high returns — Blood Suckers at 98%, Mega Joker at 99%, Jackpot 6000 at 98.9%, and this game at 98% in its mode.

The reason is structural rather than nostalgic. A classic-format game has few symbols, simple paylines, no cascades and no far tail to fund. With nothing consuming the return, almost all of it stays in ordinary outcomes.

The trade is that these games cannot produce a large multiple and will never generate a screenshot. If that does not matter to you, the retro shelf in a casino lobby is consistently the best-priced part of it.

Where this fits in a session

Used deliberately, Jokerizer is close to the best-priced game available anywhere — a 2% house edge with medium volatility, which is a combination almost nothing modern offers.

The practical approach: read the rules screen before your first spin, understand exactly what entering the mode costs and when the option appears, and then decide whether you will use it consistently. If the answer is no, play something else — a 96% retro fruit machine is not a good use of a session when Holmes and the Stolen Stones returns 96.80% with better presentation.

Budget 250 to 300 spins and set a time limit alongside the loss limit. A low-edge, medium-volatility game is comfortable enough to run for hours, and hours of anything at 2% still adds up.
