Mr Null runs the worst gift shop in the afterlife. He’s a blue-skinned, cursed shopkeeper, and the reels are his stock: a skull sealed in a jar, a haunted television, a possessed pink teddy, a houseplant with teeth. The whole slot commits to the joke, right down to the wizardly Mr Null perched on the right rail watching every spin.
Behind the novelty sits a 576-ways game with a Mystery-symbol system that can multiply itself into something loud. The wicked wares put the payout to the test.
Strip the ghoulish shopfront away, and the engine underneath is a 576-ways payer on a 3-4-4-4-3 grid, with wins landing on adjacent reels from the left. Standard enough. It’s playful-macabre rather than scary, closer in tone to the Sunnydaze Asylum demo than to true horror. The part that gives Mr Null’s its bite lives on the three middle reels, where the Mystery symbols land.
A Mystery symbol appears only on reels two, three, and four. When one lands, it carries a random multiplier from 2x to 10x, then turns into a single paying symbol chosen at random for that spin, so every Mystery on screen becomes the same icon. The trick is what happens when two or more of them join the same win. Their multipliers don’t add together; they multiply, so a pair of 10x symbols in one line turns that win into a 100x hit. That compounding is the real engine, and it’s the detail most quick write-ups flatten into a plain multiplier feature.
Three flaming-hand scatters on the middle reels award seven free spins, and every scatter that lands during the round adds one more. What makes the feature build is the persistent multiplier sitting on top of reels two, three and four. It starts at 2 and climbs by one every time a Mystery symbol hits that reel, and it doesn’t reset between spins. Late in a long round, those top numbers can be sitting well above where they began, waiting for a Mystery to cash them in.
Two Super Spin options in the bet menu guarantee Mystery symbols on every spin: Super Spin 1 at 400x for at least two, Super Spin 2 at 5,000x for at least three at higher values. They come with a sting buried in the small print. Turn either one on and the Free Spins round can’t be triggered at all. You’re trading the compounding free-spins multiplier for guaranteed Mystery symbols in normal play, and that’s a real decision rather than a free upgrade.
If you’d rather skip straight to the round, Buy Free Spins costs 100x your stake for the standard version. Buy Super Free Spins costs 300x and starts those per-reel multipliers at 5 instead of 2, so the round opens with a head start. The higher price buys a bigger number on the reels from the first spin, not extra spins.
The bet menu in Mr Null’s Wicked Wares hides more than most, and reading it before you spin pays off. Underneath the Special Bets and Buy Feature buttons, the game is a 576-ways payer staking from 20p a spin, with a demo return of 96.49%, the same adjacent-ways payline logic behind The Dog House. Operators can run slightly different builds, so glance at the paytable’s RTP line if you play beyond the demo.
One number to ignore outright is the $60,000-odd maximum bet the rules screen lists. That comes entirely from Super Spin 2, which multiplies your stake by 250 times the normal level, and it has nothing to do with what a real spin costs. Play normally and your top stake is around £240. The Ante Bet option, at three times the normal cost, makes the Free Spins five times more likely without touching the guaranteed Mystery path.
Note that in real money play, the maximum bet is often capped differently in each jurisdiction and based on individual casinos’ policies.
The skull in the jar tops the shelf at 10x your stake for five, with the haunted television, the pink teddy and the carnivorous plant filling out the premium tier. Figures scale with your bet.
| Symbol | 3 of a kind | 4 of a kind | 5 of a kind |
|---|---|---|---|
| Skull in a Jar | 1.50x | 2.00x | 10.00x |
| Haunted TV | 1.00x | 1.50x | 7.50x |
| Pink Teddy | 0.75x | 1.00x | 5.00x |
| Carnivorous Plant | 0.75x | 1.00x | 5.00x |
| Ace / King | 0.40x | 0.50x | 2.50x |
| Queen / Jack | 0.30x | 0.40x | 2.00x |
| Ten / Nine | 0.20x | 0.30x | 1.50x |
Those are useful, but not thrilling on their own. The premium symbols only really matter once a Mystery has turned into one of them and pulled a multiplier through the win.
The multiply-together Mystery system is what you'll remember about Mr Null's Wicked Wares, and it's the thing the whole game is built to show off. Two 10x symbols folding into a 100x line hit is a lovely piece of design, and the haunted gift-shop theme gives it a character few slots this size bother with. Then you meet the 5,000x cap. On a high-volatility game that's a modest limit for a feature that compounds so hard on paper, and it keeps the fireworks smaller than the setup promises. Charm and a low ceiling, in one box.
Some slots sell themselves on their numbers. Mr Null’s sells itself on its shopkeeper, and for a while that’s enough. The art is Tim Burton by way of a car-boot sale, all sickly greens and purples, and Mr Null watching from the rail gives the whole thing a personality most 576-ways games don’t reach for.
The system that makes it more than a novelty is the Mystery multiplier, and following it through is worth the effort because it’s where all the tension lives. A Mystery symbol lands on one of the three middle reels carrying a value somewhere between 2x and 10x, then commits to a single random paying symbol for that spin, so a scatter of Mysteries suddenly reads as one icon strung across the ways; if only one lands, it simply multiplies whatever win it joins, which is pleasant but tame, yet the moment two or more of them fall into the same combination their values stop adding and start multiplying into each other, turning a 10x and a 10x into a hundredfold swing and a 10x and a 5x into fifty, and in the Free Spins round that same logic sits on top of a per-reel multiplier that has been climbing by one every time a Mystery touched that reel since the round began, so a late-round line that catches two upgraded Mystery symbols on reels where the top number has crept to six or seven can detonate out of nowhere, which is exactly the sensation the game is chasing and exactly the sensation the 5,000x cap keeps cutting short.
The defence of that cap is reasonable. Keep the top win at 5,000x, and the compounding lands in a band players actually reach, rather than dangling a 40,000x lottery number nobody sees, and a game with this much character arguably doesn’t need a monster top end to justify itself. There’s something to that. The catch this review can’t get past is that a high-variance game still makes you sit through the dry spells a big top win is meant to pay off, and here that payoff is fenced in. You take the long droughts without the moonshot at the end of them.
Mr Null’s is closer in spirit to the Cult slot, another Pragmatic oddball that leads with character, than to any straight-faced high-variance grind. If you buy your slots for their world as much as their maths, that’s a fair trade. Play it in free play first, and you’ll know within a session or two whether the wicked wares are your kind of shop, because the demo makes both the charm and its limits obvious fast.
