40 Sevens Diamond Treasures is Apparat Gaming's 2026 upgrade of its established 40 Sevens formula, combining an unapologetically traditional fruit machine with the studio's newer Diamond Treasures mechanic. It was officially released on 11 March 2026, and Apparat confirms a 5x4 grid, 40 fixed paylines, medium low volatility and a maximum exposure of 12,000x the stake. The highest RTP configuration is 96.09%, although substantially lower configurations are available.
If you're looking for an elaborate theme, you've probably taken a wrong turn. Cherries, lemons, grapes, bells and big red Sevens dominate proceedings, accompanied by stacked symbols and a Diamond Wild. Apparat isn't trying to disguise the fruit machine underneath with a dragon, fisherman or suspiciously wealthy pig.
The traditional approach continues into Free Games. Three, four or five Star Scatters award 10, 15 or a rather more appealing 50 Free Games, with the Seven becoming an additional Wild for the duration. Because symbols can appear in large stacks, a reel loaded with Sevens suddenly becomes considerably more useful once those Sevens are Wild.
The real addition is Diamond Treasures. Diamonds collected during play gradually fill a treasure chest, eventually unlocking a separate 4x1 multiplier game where the reward can reach a huge 9,999x. An optional Side Bet can improve the chances of uncovering the larger rewards.
So this isn't really a completely new slot. It's 40 Sevens with another objective bolted onto the side, and that's both its strength and its limitation. Apparat has given a very simple game considerably more to chase without turning it into something its traditional audience probably never asked for.
The Diamond Wild substitutes for regular paying symbols to help complete combinations across the 40 paylines.
It's as straightforward as Wilds get, but that's entirely appropriate here. The base game isn't supposed to require an instruction manual. Diamonds also form the basis of the Diamond Treasures side game, so there's at least some consistency between the game's visual identity and its headline feature.
Nothing revolutionary. Just a diamond doing its day job.
Regular symbols can appear in large Stacks, potentially occupying substantial sections of a reel. Apparat specifically highlights this mechanic because of the way it interacts with the Seven during Free Games.
Stacked symbols give the otherwise simple base game some visual anticipation. Seeing several matching symbols covering neighbouring reels can quickly create sizeable combinations across the fixed paylines.
They're much more interesting during Free Games, though, because stacks of Sevens effectively become stacks of Wilds.
Landing three Star Scatters triggers 10 Free Games, four award 15, while landing all five produces a substantial 50 Free Games.
I like the size of that jump. Lots of slots provide a token couple of additional spins for landing an extra Scatter. Here there's an enormous difference between triggering the minimum and managing to land all five.
The bonus itself isn't complicated. There are no branching paths, collection meters or progressive multipliers suddenly appearing. Instead, Apparat makes one important change to the existing reels.
During Free Games, the regular Seven becomes an Additional Wild, joining the Diamond Wild.
It's a very simple modifier, but one that makes sense because of the Stacked Symbols mechanic. A large block of Sevens that would ordinarily be another premium symbol can now provide extensive Wild coverage.
This is probably the best part of the traditional slot itself. Apparat hasn't invented another feature for the sake of it. It simply makes one of the game's existing symbols considerably more powerful.
Get the full 50 Free Games and those stacked Wild Sevens have plenty of time to earn their keep.
The Diamond Treasures side game introduces persistent collection alongside the conventional reel action. Every qualifying Diamond contributes towards filling the treasure chest. Once the chest is complete, it opens and provides access to the dedicated multiplier game.
This is what prevents 40 Sevens Diamond Treasures from feeling like a straight rerelease.
Even during fairly uneventful base game spins, there's another objective developing outside the ordinary paylines. It isn't particularly complicated progression, but a visible collection target is enough to give regular play some additional purpose.
Completing Diamond Treasures unlocks a separate 4x1 Multiplier Slot, which awards a random multiplier potentially reaching an enormous 9,999x. Apparat confirms the game's overall maximum exposure is capped at 12,000x.
It's an interesting contrast with the rest of the game.
Most of 40 Sevens is extremely conservative in design, then hidden inside the treasure chest is a multiplier capable of reaching nearly ten thousand times the stake.
Apparently the fruit machine has been quietly saving up.
Players can increase the Diamond Treasures Side Bet, with higher participation improving the chance of uncovering the feature's larger rewards.
For our terminology, I'd classify this as a Feature Bet. It modifies access to and the potential of Diamond Treasures rather than constituting another bonus feature itself.
It's also important editorially because the Diamond Treasures experience isn't completely independent of stake configuration. Players should understand that the optional Side Bet affects the feature.
Apparat officially lists Buy Feature configurations ranging from 35x to 410x the stake.
As we've established across these reviews, the presence of a Bonus Buy doesn't improve our rating by itself. It's simply an alternative way of accessing the game's features.
This is where I think we were too generous when we originally gave it 7.5.
The underlying gameplay is deliberately basic. You've got 40 paylines, Stacked Symbols, a Wild and traditional fruit machine wins. Diamond collection gives regular spins another objective, but it doesn't fundamentally transform what's happening on the main grid.
The low to medium volatility also tells us something about the intended experience. Apparat rates it just 2/5 for volatility, with a 15.57% hit rate in its published configuration.
That's perfectly legitimate design. Not every slot needs explosions every three spins. But within our rating system, "pleasant and straightforward" shouldn't automatically become a 7.5.
There's more here than the base game initially suggests.
Free Games can provide as many as 50 spins, and converting stacked Sevens into Wilds is an effective enhancement. Diamond Treasures then provides an entirely separate progression mechanic culminating in that potentially enormous 9,999x multiplier.
But we've now reviewed slots such as 5K Gold Mine Dream Drop and Dungeons & Dragons Power Combo, and that gives us a much better benchmark for what an 8.5 or 9 feature package actually looks like.
40 Sevens doesn't belong in that territory.
The features are good additions to a simple game rather than an exceptional collection of interacting mechanics.
It's polished, exceptionally clear and does the classic fruit machine look well.
The problem is that Apparat has deliberately chosen some of the most familiar imagery imaginable. Fruit, bells, Sevens and diamonds aren't going to win many awards for artistic ambition.
Diamond Treasures adds some welcome visual polish through the chest and multiplier game, while the large stacked symbols work nicely on the 5x4 grid. Independent descriptions similarly characterise the presentation as a modern polish on a retro fruit machine aesthetic.
It looks good for what it is. What it is just isn't particularly exciting.
This is another area where our original 7.0 was too high.
Apparat itself describes the game as the familiar 40 Sevens experience enhanced with Diamond Treasures. That's an accurate description.
Stacked fruit symbols, Sevens becoming Wild during Free Spins and fixed paylines are all extremely established mechanics. Even collection meters and random multipliers are hardly unusual in 2026.
Diamond Treasures gives this edition something the original didn't have, and the 4x1 multiplier game is an interesting addition. But adding a good feature to an existing slot doesn't suddenly make the overall design highly original.
It's a successful upgrade, not a reinvention.
Overall Rating
6.9/10
40 Sevens Diamond Treasures knows exactly what it wants to be: an old fashioned fruit slot with one considerably more modern trick hidden inside the chest.
The 40 payline base game is extremely straightforward, although Stacked Symbols provide some anticipation and become considerably more useful when Sevens turn Wild during Free Games. The possibility of triggering 50 Free Games is also a nice touch.
Diamond Treasures is what really improves proceedings. Collecting Diamonds gives ordinary spins another objective, while eventually opening the chest provides access to a multiplier game capable of reaching 9,999x.
It's enjoyable without being particularly ambitious. Players who like classic fruit machines get something familiar with an extra chase attached, while those looking for elaborate modern mechanics will probably find the cupboard rather bare once the diamonds have been put away.
