Multidiamond XXL: Spins+ Review

Multidiamond XXL: Spins+ is another supercharged, classic-themed online slot by Playson packed with rock’n’roll and glittering gems. It is set to hit the market in the first week of November 2026 and brings new features and a potentially huge payout cap. The provider takes a new direction and has added special bets and bonus buys to this electrified spinner!

Playson is a privately held studio focused on the development of premium, classic online slots with modern features. It is headquartered in Malta and was founded in 2012. Playson is an award-winning provider, and one of its latest recognitions was at the iGB Affiliate Awards 2025, where the studio won in the “Best Game of the Year” category for Supercharged Clovers: Hold and Win. It is fully certified and licensed to operate in 30+ regulated markets.

Multidiamond XXL: Spins+ comes full of energy and with a 3x5 grid, generating 15 paylines on every spin. Multidiamond Feature and Collect Feature are active in both the base stage and Bonus Game. They are packed with multipliers, jackpot prizes, and a brand-new Spins+ Feature. If all that sounds enticing, make a few test spins via the Multidiamond XXL: Spins+ demo and continue with my dedicated review!

Multidiamond XXL: Spins+ Slot - Reels Screen

Multidiamond XXL: Spins+ pays when 3 regular symbols of the same type land on the active lines, from left to right. They all land in stacks, which means multiple possible payouts per spin. Diamonds are cash symbols and they do the same, so a collector can add a significant prize to the line wins if any. Sadly, the online slot lacks wilds and scatters, so let’s check the regular symbol payouts!

Triple Sevens pay the most - 30x the bet, followed by Bells - 10x and Dice - 8x. Red BARs and Black BARs award 4x each, while the Spades, Diamonds, and Hearts card suits pay 1x. The lowest-value symbol is the Clubs suit - 0.50x the stake. The betting range is wide, but also configurable. If not further limited by casino operators, it starts from €0.10 to €100 per spin, up to €700 via the special bets.

The Multidiamond XXL: Spins+ RTP rate is unknown since the provider didn’t share official technical information yet. It’s typical for Playson, and I had to do deep research to find any details. Keep in mind that these are rather rumors than confirmed facts. According to several online sources, the RTP rate is 95.64%, while the featured levels of volatility are medium to high. The Hit Frequency coefficient is about 14% - 15%, and the Multidiamond XXL: Spins+ max win is 7,347x the bet!

Multidiamond XXL: Spins+ Features

Multidiamond XXL: Spins+ offers several special features, including Pile of Diamonds, Multidiamond, Collect, and Spins+. The bonus minigame is based on the classic Hold & Win, which Playson heavily prefers in its slot collection. However, in this particular game, it is modified and relies on exhaustible spins rather than respins, which reset under certain rules. Find out more information in the following paragraphs:

Pile of Diamonds Feature

Pile of Diamonds is a Symbols Collection mechanic, which is active during the base game. A pot located on the left side of the reels collects all types of Diamonds that land but do not trigger the bonus game. Pile of Diamonds can randomly activate on any such spin and add Multidiamond, Collect, or Diamond symbols on random positions, in quantities enough to trigger the bonus.

Multidiamond Feature

Multidiamond Feature is the base of this online slot and is associated with a special Multidiamond Symbol. It can land on reel 2 only, and when it does, it acts as a Collector Symbol. Each one will accumulate all the Diamond cash and jackpot values in view and will boost the total with a random multiplier of x2, x3, x5, x7, x10, x15, or x20. Multidiamond Symbol can be randomly added on any base game spin if at least one Diamond is in view.

Collect Feature

Diamonds land on reels 1 and 3 in all game stages and carry cash values and jackpot prizes. Collect Diamonds are collectors and land on reels 2 only in both the base game and free spins. Each Collect Diamond accumulates all cash and jackpots and pays them off.

• Grand Jackpot - 1,000x the bet
• Major Jackpot - 100x the bet
• Minor Jackpot - 30x the bet
• Mini Jackpot - 15x the bet
• Diamond Cash Values - 1x, 2x, 3x, 4x, 5x, 6x, and 8x the bet

Bonus Game

At least one Multidiamond Symbol or Collect Diamond on reel 2, along with at least one Diamond on reels 1 or 3, activate the bonus game. It starts with 7 free spins, and all symbols on reel 2 are sticky. They collect all Diamond cash and jackpot values throughout the minigame. Multidiamond Symbols can apply random multipliers more than once! Spins+ Feature may award extra free spins via the +1, +2, and +3 symbols.

Special Bets & Buy Bonus

Special Bets are ante bets and help you get the bonus feature more frequently. There are 3 options in the menu, and the first two boost the odds by 2 and 5 times, but will increase the selected wager by 50% and 250%, respectively. The third bonus bet runs a new set of reels with bonus symbols only.

It costs 7x the bet and increases the chance of triggering the Bonus Game 5 times and guarantees at least one Multidiamond Symbol or Collect Diamond per featured spin. Buy Bonus is also available, but it is optional and may be disabled due to regulatory restrictions or at the operator’s discretion in certain regions. If not, you can purchase a standard bonus for 75x the bet, or an enhanced mode with 2 Multidiamond Symbols guaranteed for 250x the bet.

Theme & Graphics

Multidiamond XXL: Spins+ is charged with electricity and lightning bolts like many of the Playson games. But that doesn’t change the fact that it is still a classic online slot with diamonds, sevens, bells, BARs, and card suits on the reels. The backdrop stands out in a deep, rich shade of dark red, while the pile of diamonds on the left catches the eye. The quality of graphics and animation effects is up to par with the provider’s distinguished quality.

Multidiamond XXL: Spins+ offers generic gambling effects and rock’n’roll audio when spinning the reels. That raises the tone and tension even higher, making every spin full of anticipation and energy. As usual, the online slot is fully compatible with Android and iOS mobile devices. It is light and loads easily via any browser!

Pros And Cons Of Multidiamond XXL: Spins+ Slot

Our Verdict

Multidiamond XXL: Spins+ offers feature-rich gameplay in Playson’s style with a potential good payout rate. Not the best, though, but the provider prefers to keep the specs on the line and to compensate with strategy-friendly games filled with entertainment. In fact, the lack of official RTP information is probably the only significant flaw of the title. And the overused concept, but fans will enjoy it anyways!

Features run fast and spectacular, like in other similar titles, including Coin Strike XXL: Multicoin and Diamonds Power XXL: Hold and Win. Multidiamond Symbols and Spins+ Feature are the new stuff, and they add extra layers to the fun. I like the way multipliers boost the accumulated cash and jackpots and the fact they can hit more than once in the bonus game.

Hold & Win that feels like Free Spins is what makes Multidiamond XXL: Spins+ almost unique in the Playson collection. Yet, the concept remains more or less the same, with cash and jackpot values landing in stacks on reels 1 and 3, and sticky collectors on reel 2. Audibly and visually, the game is a real treat, and that's no minor benefit fully comparable to the feature set. Furthermore, the selection of special bets and bonus buys feels like a new direction for the studio, up to one of the hottest trends right now!
