About The Sword and The Grail
The Sword and the Grail's 96.53% RTP is honest — it is just stored almost entirely in a King of Knights stage that an independent 1,350-spin test reached precisely zero times.
Despite the middling headline, the RTP is wildly back-loaded into a Stage 4 (King of Knights) free-spins outcome almost nobody sees. Reaching it requires collecting 18 scatters during a feature that starts with only 5 spins. An independent 1,350-spin test documented 17 bonuses averaging just 26x, with the session never genuinely clearing Stage 4. The 100x Wild multiplier is closer to a marketing number than a realistic outcome.
Variable RTP: 96.53% / 94.50% / 91.32% / 87.35% / 84.63%. Two UK-licensed operators confirmed deploying the 94.50% tier: LV BET and Fluffy Spins. The 2.03pp gap between their deployment and the provider default roughly doubles the house edge — from 3.47% to 5.50%.
The 2024 sequel Excalibur (96.20%, 25,000x, sticky wilds) is strictly easier to engage with. Pick the original only for the cleaner math and marginally better default RTP.
Key Features
Four-Stage Bonus Ladder
Knight, Bishop, Queen, King of Knights. Each stage requires more scatters than the bonus realistically delivers.
Back-Loaded RTP
An independent 1,350-spin test never cleared Stage 4. The 100x wild multiplier is functionally inaccessible.
5-Tier Variable RTP
96.53% / 94.50% / 91.32% / 87.35% / 84.63%. LV BET and Fluffy Spins (UK) confirmed at the 94.50% tier.
Doubled House Edge
94.50% deployment vs 96.53% default raises house edge from 3.47% to 5.50% — roughly a 2x increase.
Excalibur Sequel (2024)
Strictly easier to engage with — 96.20% RTP, 25,000x cap, sticky wilds. Pick the sequel for max-win hunting.
