Page updated July 2026
This version of Excalibur VS Gigablox slot is listed under provider Reelplay and shares the same warrior-clash concept as its sibling release, playing out on a 6-reel grid with 50 paylines and the Gigablox mechanic that lets oversized symbol blocks fill anywhere from 2x2 up to the full 6x6 span of the screen. Standard wins need matching symbols to land on adjacent reels from the first reel outward, and because Gigablox blocks can appear on any non-wild, non-scatter position, a single spin can deliver several connected combinations at once.
Rather than a single mythological setting, the design pulls fighters from a range of legends into one arena — Arthurian, Irish, Chinese, Germanic, Japanese and Greek heroes are all represented on the paytable alongside J-to-A card ranks as the lower-value symbols. The backdrop is a battle-worn field of flames and planted swords, and the bonus round stages a direct face-off between two of those champions, giving the feature its own dramatic framing separate from the base game reels.
With an RTP of 96%, this build of Excalibur VS Gigablox slot returns a noticeably healthier theoretical percentage than some of its Gigablox stablemates, putting it close to the industry standard for the format. That figure edges up slightly further when the bonus round is bought outright, which is typical for slots that offer an instant-feature option.
The listed volatility sits at medium/high, a touch gentler than a straight high-volatility rating, which fits with the recorded hit frequency of 27.17% — a hit landing on roughly one in four spins, giving the base game a steadier rhythm than the swingiest Gigablox releases while still leaving room for the Gigablox blocks to create outsized combinations when they land favourably.
The maximum win is capped at 4,050x the triggering bet, matched to a stake range that runs from 0.50 up to 60 per spin. That top end of the betting range isn't especially low-roller friendly, so it's worth dialling stakes down carefully if you're planning a longer session rather than a handful of big spins.
This Excalibur VS Gigablox slot leans on a recognisable mash-up of legendary warriors and the tried-and-tested Gigablox block format, and its medium/high volatility with a near one-in-four hit rate makes it a slightly friendlier entry point into the mechanic than its higher-volatility counterpart.
