Excalibur VS Gigablox

Excalibur VS Gigablox Slot Review

Excalibur VS Gigablox is a battle-themed video slot released through Yggdrasil's partner network, built on the Gigablox engine that turns oversized symbol blocks loose on a 6-reel, 6-row grid. Wins are formed the usual way, with three or more matching symbols connecting from left to right, but 50 active paylines and blocks stretching from 2x2 all the way up to a full 6x6 mean a single tumbling sequence can pay out several times over before the reels settle.

Theme and gameplay feel

The setting is a scorched, weapon-strewn battlefield where armoured champions from different legends face off over the legendary sword. Swords, shields and glowing runes fill the paytable, and the presentation leans hard into cinematic drama every time a Gigablox lands or the Excalibur Wild feature fires. It's a loud, muscular game rather than a relaxing one, and that tone carries through into how the mechanics behave.

Gigablox symbols break apart into their individual pieces once they're involved in a win, which is what lets the grid keep refilling and chaining extra payouts from a single spin. Randomly, one of those Gigablox blocks can transform entirely into wilds, and landing five or more Gem symbols kicks the reels into the Highrise Respins round, where sticky multipliers sit along the top row and boost the Gem values collected beneath them. Every new Gem or Multiplier that lands resets the respin counter back to three, so a hot run can genuinely snowball before the feature ends.

What the RTP and volatility mean for you

Excalibur VS Gigablox slot carries a listed RTP of 94%, which sits a little under the market average, so the theoretical return skews slightly more toward the operator over a large number of spins than many rivals in the Gigablox family. Paired with a high volatility rating, that lower baseline return is the trade-off for the size of the swings on offer — expect longer dry stretches between meaningful hits, punctuated by the odd Highrise Respins round that can transform the balance in a hurry.

Max win and stake range

The ceiling here is 4,050x the triggering stake, a solid if not chart-topping figure for a Gigablox title, built almost entirely around how far the sticky multipliers climb during Highrise Respins. Stakes run from 0.50 up to 60 per spin, giving a reasonably wide betting range for both cautious players and those chasing the bigger multiplier stacks. A bonus buy option is also available on supported platforms, letting players skip straight into the Highrise Respins feature with every core mechanic still fully active.

Verdict

Excalibur VS Gigablox slot is a solid pick for players who enjoy the tumbling, ever-growing block format and don't mind a high-volatility ride to get there. The warrior theme is well executed even if it isn't groundbreaking, and the Highrise Respins engine gives the bonus round genuine tension.
