Thunder Diamonds: Hold and Win Review—Editor’s Impressions

NeverEnding is taking us on a trip to the golden age of slots in the retro-inspired Thunder Diamonds: Hold and Win slot machine. It adopts a classic layout, adds dynamic animations and beautifully illustrated symbols, and caps it all off with multiple jackpots and a big bonus feature. Learn more in this Thunder Diamonds: Hold and Win slot review.

Thunder Diamonds: Hold and Win Slot Overview

Developed by NeverEnding, Thunder Diamonds: Hold and Win features a 3x3 grid and five paylines dominated by Diamonds and other classic slot symbols. The 7 is the game’s Wild and highest payer, with others including Bells, Dice, BARs, and playing card suits. You need matching symbols on all three reels to trigger a payout, and there are two features up for grabs (discussed below).

Thunder Diamonds: Hold and Win RTP, Payout, and Volatility

The Thunder Diamonds: Hold and Win RTP is a strong 96.08%, slightly above average for video slots.

Max payouts rarely tip the scales on retro-themed online slots, especially with just five paylines. However, at up to 3,000x, the top payout here is higher than expected. It still pales in comparison to other modern titles, but it’s a decent target. The biggest payouts come via the bonus features.

The developer doesn’t list the volatility in the game files or on its website. Play the Thunder Diamonds: Hold and Win slot demo to get a feel for this metric.

Thunder Diamonds: Hold and Win Mobile

If you like your mobile slots fluid, classy, and vintage, play Thunder Diamonds: Hold and Win on iOS or Android. It looks great in both landscape and portrait mode, with a clean backdrop, compact layout, and accessible controls. There are no complicated features or mechanics getting in the way, just classic slot gameplay.

Thunder Diamonds: Hold and Win Graphics and Gaming Experience

We encounter many vintage titles in our slot reviews, and while this NeverEnding game adopts a similar style, the backdrop—sparkling diamonds, bolts of electricity—is more dynamic than what you typically see.

It’s retro, but with a modern gloss and bold colours that give it a distinctive style.

Thunder Diamonds: Hold and Win Bonus Features

The first of the game’s two features is the Thunder Diamond Bonus, which triggers when you land the Thunder Diamond Bonus symbol alongside any other Diamond Bonus symbol. Once activated, the feature grabs all of the Bonus symbols on the reels, including Mini, Minor, Major, and Grand jackpot icons.

The jackpots offer up to 1,000x, with the amounts fixed to your stake and shown above the reels at all times. The main feature is the titular Hold and Win round. It launches when there’s at least one Bonus symbol on the reels.

Thunder Diamonds: Hold and Win Free Spins Feature

Although it’s not quite a Free Spins round, the Hold and Win bonus comes pretty close. It launches with an initial three respins but resets the counter every time you reveal a new Bonus symbol. Only Bonus and Thunder Diamond Bonus symbols can appear during this feature, with the latter appearing on the middle reel and sticking around for the duration.

Each symbol displays a monetary amount from 1x to 20x, and once the round is over, these amounts are combined and paid.
