Slots Like Sword of Arthur: A Multiplier That Never Resets
Sword of Arthur pulls Thunderkick away from cascading grids and back to a fixed 5 reel, 3 row, 10 payline layout, built around Arthurian legend symbols like the King, a helmet, a shield and a suit of armour. Three or more sword scatters award 3, 4 or 5 free spins depending on the count, and inside the round one random symbol expands to cover a whole reel whenever it forms part of a win, with only a single symbol able to expand per reel on any given spin. Every expanding win raises a Power multiplier by one level and, crucially, resets the remaining spin count back to its original total rather than simply adding a couple more on top, so a hot streak can keep the round running far longer than its starting allocation. Three feature buy tiers offer different starting points: a straight 125x stake buy, a 200x stake buy guaranteeing 5 spins, and a 500x stake buy guaranteeing the high paying King Arthur symbol is already in play. The RTP lands at 94.34%, this one carries a high volatility rating, and its top payout caps at 10,000x the stake.

Sword of Arthur keeps things deliberately traditional next to Thunderkick’s usual house style: a static 5 reel, 3 row grid with 10 fixed paylines, no cascades and no shifting symbol counts. Card ranks from 10 through Ace fill out the low end of the paytable, while King Arthur himself, a helmet, a shield and a suit of armour carry the higher payouts, alongside a wild symbol and a sword scatter.
Nothing about the base game deviates from a conventional payline structure, which puts the emphasis squarely on the bonus round rather than any base game surprises.
Free Spins and the Power Multiplier
Landing 3, 4 or 5 sword scatters awards 3, 4 or 5 free spins respectively, a noticeably tighter starting allocation than many rival slots. The trade-off comes from the Power multiplier: during the round, one random symbol on the grid can expand to cover an entire reel whenever it forms part of a winning combination, with only one expanding symbol permitted per reel on a given spin. Every expanding win bumps the Power multiplier up by one level and resets the remaining spin count back to its full original total, meaning a productive stretch of expanding wins can keep the round alive well beyond its opening handful of spins.
Feature Buy Options
Three feature buy tiers sit alongside the standard spin button: a 125x stake buy drops straight into a normal free spins entry, a 200x stake buy guarantees the round opens with 5 spins already in hand, and a 500x stake buy guarantees King Arthur himself, the game’s top paying symbol, is on the grid from the very first spin of the round.
Pros and Cons
Pros
- Resetting the spin count on every expanding win gives skilled or lucky sessions genuine room to snowball
- A 10,000x ceiling holds up well against other high volatility Thunderkick releases
- Three distinct feature buy tiers let players choose exactly how much of a head start they want to pay for
- The Arthurian legend presentation is polished and atmospheric throughout
- A fixed payline structure will appeal to players who prefer a more traditional, easy to read format
Cons
- The starting allocation of just 3 to 5 free spins is stingy if the Power multiplier fails to build early
- A 94.34% RTP sits on the lower side even accounting for the small Bonus Buy bumps
- The fixed 10 payline base game offers little of interest outside the bonus round
- Players used to Thunderkick’s more experimental releases may find this one comparatively conventional
Game Screenshot
Give the free demo a proper go and watch how quickly the Power multiplier climbs, since that’s the clearest way to judge whether any of the three feature buy tiers are worth paying for.
Expert Take
Reviewers generally see the resetting spin count as the standout idea in Sword of Arthur, since it turns what looks like a stingy 3 to 5 spin starting allocation into a round with genuine snowball potential once the Power multiplier gets moving. The base game itself draws less enthusiasm, with its fixed payline structure viewed as a deliberately conventional backdrop for the bonus feature rather than an attraction in its own right.
Similar Slots to Try
The Arthurian and wider medieval setting is the main draw for players landing on this page. These seven sit in similar territory.
- Ivanhoe
A medieval knight themed slot with its own jousting-inspired bonus mechanics, playing off the same chivalric imagery as Sword of Arthur but with a different reel structure underneath. - Mighty Black Knight
Another armoured knight themed release, leaning harder into a dark, dramatic tone than the more classic Arthurian framing here, but worth a look for fans of the setting. - Black Knight
A long-running medieval themed title with its own distinct feature set, one of the older entries in this space and a useful reference point for how the theme has evolved. - Knights Keep
A castle and knights themed slot covering similar Arthurian-adjacent ground, built around a hold and win style bonus rather than the mechanic used in Sword of Arthur. - King Arthur
A Microgaming release that takes on the Arthurian legend directly rather than adjacent knight imagery, with its own free spins structure. The closest thematic match on this list. - Avalon 2
A Microgaming sequel built around Arthurian legend with a multi-stage bonus wheel format. Another strong thematic fit alongside its own King Arthur release. - Grand Melee
A carnival tournament theme from Thunderkick, where the win-forming action comes from a random Sticky Respin trigger rather than a multiplier that keeps climbing without ever resetting. - Donny Dough
Builds its payouts from four distinct Multi-Dough symbol types rather than a single ever-climbing multiplier, alongside a choice between two bonus formats.
About the Developer
Sword of Arthur comes from Thunderkick, and it is a noticeably more restrained release than much of the studio’s catalogue, trading experimental reel formats for a traditional fixed payline structure with all of the innovation concentrated into the free spins multiplier system instead. It is a useful reminder that the studio is capable of working within a conventional format as well as breaking from it. See more on our Thunderkick slots page.

Our Verdict on Sword of Arthur
Sword of Arthur works because it commits fully to one idea rather than spreading itself across several: a resetting spin count that rewards a hot run of expanding wins with a genuinely extended free spins round. The fixed payline base game will not excite players chasing modern cascading formats, and a below average RTP is worth factoring in, but for anyone who enjoys watching a multiplier climb and a bonus round refuse to end, this is a well constructed, if narrowly focused, release.
