777 Diamond Strike: Slot Overview
Diamonds and the number 7 are common online slot items, presumably on account of their association with wealth and luck, respectively, and both are extensively used in the Red Tiger release 777 Diamond Strike. Not for the first time, either. This is because 777 Diamond Strike is a remake of 777 Super Strike, with the two games sharing a triple-level free spins feature that players can dive deeper into if the round retriggers. If this sounds rabbit hole-ish, that’s no coincidence, as both titles share a common ancestor in the form of In the Rabbit Hole.
Can’t deny, 777 Diamond Strike looks very much like its predecessor did, though a few visual upgrades have taken place. The background is sparklier; it’s got little diamond shapes amongst its patterns, just in case, you know, there aren’t enough diamonds on the screen already. The non-diamond pay symbols have even been designed to look like cut gemstones, and the soundtrack has a toe-tapping, twinkling property. It’s all fine if you like this sort of yesteryear thing.

777 Diamond Strike has one of those white backgrounded gaming areas consisting of 5 reels, landing 3 symbols on each. 10 paylines are incorporated, and if you look above the grid, you can see how much each winning combination is worth. Medium/high volatile, players can stake 10 c to $/€20 per spin while expecting a theoretical RTP of 95.73%.
The J-A card royals have little diamonds on them, and they’re joined by cherries, lemons, sevens, double sevens, and triple sevens. Five-of-a-kind royal wins pay 7.7x the bet, while non-royal 5 OAKs are worth 14.7x to 77.7x the bet. Regular wilds hit on all reels, substituting for all paying symbols. Diamond Wilds land on reels 2, 3, and 4. A Diamond Wild covers the entire reel if it participates in a winning line. If a winning line consists of 5 wilds, players collect 77.7x the bet.
777 Diamond Strike: Slot Features

Like those that came before, 777 Diamond Strike’s main feature is a triple-level free spins round accessible when retriggers occur.
7th Heaven
Players win 7 free spins when 3 scatters land on the leftmost, middle, and rightmost reel. On every 7th spin, there is a chance of a free spins retrigger for a total of up to 21 free spins. The first retrigger upgrades free spins to win spins, and the second retrigger upgrades win spins to wild spins. No more retriggers may occur after that.
- Free Spins – 7 free spins with more 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
Using the bonus buy option, players can trigger free spins at a cost of 100 times the bet.

777 Diamond Strike: Slot Verdict
It’s hard to think of much to say about 777 Diamond Strike, which hasn’t already been said about 777 Super Strike or In the Rabbit Hole. The goal of triggering free spins to start the rabbit hole journey through deeper and deeper layers of free spins remains, each retrigger unlocking a batch of free spins that’s more potent than the last. It might have been interesting if Red Tiger had come up with a fourth, even deeper free spins round to give 777 Diamond Strike extra legitimacy, but no, players will have to content themselves with free spins to win spins to wild spins if the game is on a retriggering run.
One piece of positive news that might motivate gamblers to choose this over its predecessor is higher winning potential of 4,186.6x the bet, a good chunk more than the figure 777 Super Strike posted. Otherwise, the ways-to-win to payline shift emphasises the old-fashioned feel, and winning combination values have increased. Swings and roundabouts, though? The base game is okay, relatively speaking, as Diamond Wilds land in that phase of play to spike interest, but as before, free spins are definitely the main event, and they’ve got their moments when retriggers are happening.
Though there was no mention of this, it might be assumed Red Tiger designed 777 Diamond Strike after receiving feedback about 777 Super Strike – pepping up the winning potential being one obvious way the previous game might have been improved. If that is the case, then players who were tempted by the last slot but wanted a bit more get this in 777 Diamond Strike, though it’s not a significantly more exciting release.
