Page updated July 2026
Landing on 20th July 2026, Henry 8th: Calves of Steel is Hacksaw Gaming's next comedic swing at British history, taking Henry VIII and giving him an entirely fitness-obsessed makeover across a high-volatility 5-reel, 5-row grid. Confirmed to run on 19 paylines evaluated left to right, the game leans on Walking Wild symbols as its central mechanic, with those wilds able to expand, travel across the reels, and carry multiplier values as they go, backed up by respins and two separate Free Spins paths.
Visually, expect a humorous royal Tudor setting built around exaggerated fitness imagery layered over castle backdrops, royal iconography, and bold, cartoonish character design, all wrapped in modern animation work despite the joke-heavy "calves of steel" premise. Hacksaw Gaming has a track record of pairing comedic themes with genuinely serious math models, and this release looks set to continue that pattern.
The confirmed Free Spins feature triggers from 3 or more scatter symbols, awarding 8 free spins with Walking Wild multipliers reported to range from 1x up to 100x depending on which version of the feature is active, while extra scatters landing during the round can add further spins. An enhanced spin option, similar to an Ante Bet, is also planned to increase the chance of triggering the feature, alongside a Bonus Buy menu offering multiple ways to purchase entry directly.
Numbers-wise, Henry 8th: Calves of Steel is confirmed for an RTP of 96.32%, high volatility, and a maximum win of 10,000x the stake, with stakes expected to run from 0.10 to 100 per spin. It's worth noting that RTP can vary between operators, so always check the in-game figure once live.
