777 Diamond Strike: Slot Overview

Diamonds and the number 7 are classic online slot staples—linked to riches and luck—and both are heavily featured in the Red Tiger release 777 Diamond Strike. It’s also not the first time they’ve done it. 777 Diamond Strike is a remake of 777 Super Strike, and the pair share the same triple-tier free spins mechanic that can pull players further in whenever the bonus retriggers. If that sounds like going down a rabbit hole, it’s fitting, since both games trace back to In the Rabbit Hole.

Visually, 777 Diamond Strike stays very close to the earlier game, although there are a few polish upgrades. The backdrop has more sparkle, with small diamond motifs woven into the pattern—just in case the reels weren’t already diamond-heavy enough. Even the non-diamond symbols are styled like faceted gems, and the music has a bright, tinkly, foot-tapping vibe. It works well enough if you’re into that retro-leaning look and feel.

777 Diamond Strike uses a white-backed play area with 5 reels, showing 3 symbols per reel. There are 10 paylines, and the payout values for each winning combo are displayed above the grid. Rated Medium/high volatile, players can stake 10 c to $/€20 per spin, with a theoretical RTP of 95.73%.

The J-A card royals feature small diamond details, alongside cherries, lemons, sevens, double sevens, and triple sevens. A five-of-a-kind royal win pays 7.7x the bet, while non-royal 5 OAK results return 14.7x to 77.7x the bet. Standard wilds can appear on any reel and substitute for all paying symbols. Diamond Wilds show up on reels 2, 3, and 4. A Diamond Wild expands to cover the full reel when it forms part of a winning line. If a winning line is made up of 5 wilds, the payout is 77.7x the bet.

777 Diamond Strike: Slot Features

As with the earlier versions, the headline feature in 777 Diamond Strike is its three-stage free spins bonus, which only reveals deeper levels when retriggers land.

7th Heaven

Players receive 7 free spins when 3 scatters appear on the leftmost, middle, and rightmost reel. On every 7th spin, there’s a chance to retrigger the bonus, allowing a total of up to 21 free spins. The first retrigger upgrades free spins into win spins, and the second retrigger upgrades win spins into wild spins. After that, no further retriggers are possible.

• Free Spins – 7 free spins with extra wilds and Diamond Wilds added to the reels.
• Win Spins – 7 free spins where every spin is a guaranteed win.
• Wild Spins – 7 free spins where every spin is a guaranteed win, and wilds lock to the reels for the remainder of the bonus round.

Feature Buy

With the bonus buy option, players can activate free spins for 100 times the bet.

777 Diamond Strike: Slot Verdict

It’s difficult to find much to add about 777 Diamond Strike that hasn’t already been covered with 777 Super Strike or In the Rabbit Hole. The core aim is still to trigger free spins and then chase retriggers that take you into progressively stronger layers of the bonus, with each step delivering a more powerful set of spins than the previous one. It could have been more compelling if Red Tiger had introduced a fourth, even deeper free spins stage to help 777 Diamond Strike stand out more, but instead it remains free spins to win spins to wild spins when retriggers line up.

One clear plus that may push players toward this version is the increased maximum win of 4,186.6x the bet, which is notably higher than what 777 Super Strike offered. Beyond that, the move from ways-to-win back to paylines reinforces the old-school tone, and payout values for winning combinations have been boosted. There are trade-offs, though. The base game is reasonably engaging thanks to Diamond Wilds appearing during regular play to add some spikes of excitement, but as before, the free spins round is the real highlight—especially when retriggers start to land.

Although it isn’t stated outright, it’s easy to imagine Red Tiger built 777 Diamond Strike in response to feedback on 777 Super Strike, with the improved win potential being an obvious area to strengthen. If that’s the case, then anyone who liked the previous slot but wanted a bit more will find it here in 777 Diamond Strike, even if it doesn’t feel like a dramatically more thrilling release.
