A second, closely related release, Notre-Dame Tales GigaBlox, also comes from Yggdrasil and shares the medieval Paris setting of its sibling title, but this version is built on its own 6-reel, 4-row grid, paying via matching symbols across adjacent reels rather than a fixed payline count.
This version leans into the same legendary medieval world, complete with the Notre-Dame cathedral, knights, gargoyles, and treasure-hunting stars, but pushes the GigaBlox mechanic even further, with symbol blocks capable of growing as large as a full 6x6 grid. Animations around these giant block formations, along with treasure chest reveals, give this edition a grander, more spectacular feel than a standard cascading slot. Free spins here come with a genuine twist system: rather than one fixed bonus, players can land Wild High, an x2 Multiplier, Expanded Reels, an Extra Wild, High Stacks, or additional free spins, each altering how the round plays out. A treasure chest can also appear mid-feature to award cash prizes or extra spins, while a Golden Bet or Buy Bonus option offers a faster route into the free spins for players who don't want to wait.
This edition also returns 96% to players over time, matching the wider Notre-Dame Tales series and sitting right at the commonly cited slot industry benchmark.
Rated medium volatility, this GigaBlox version is pitched as a slightly steadier experience than its higher-volatility sibling, with the adjacent-reels win mechanic and expanding blocks providing regular opportunities for wins to connect without demanding extreme patience.
The maximum win here is 3,690x the stake, very close to the sibling title's ceiling but reached through a different route, primarily the 6x6 GigaBlox formations and the free spins twist system. Betting runs from 0.25 to 100 per spin, matching the wider series.
This GigaBlox edition of Notre-Dame Tales stands as its own release rather than a simple reskin, thanks to the adjacent-reels payout mechanic, the twist-based free spins, and blocks that can swell to a full 6x6. With a fair 96% RTP and approachable medium volatility, it's a strong pick for players who enjoyed the original setting but want a different feature mix.
