Notre-Dame Tales GigaBlox (Yggdrasil Gaming) – Review & Demo Play

The Notre-Dame Tales GigaBlox Slot Game

Notre-Dame Tales GigaBlox drops me into Paris by the cathedral, with characters straight from Victor Hugo’s tale. The action plays on 6 reels with 4 to 6 rows, giving 25 to 40 paylines as the grid shifts. On every spin at least two reels connect to form GigaBlox, with blocks up to 4x4 in the base game. I can play on desktop or mobile, and wins land when three or more matching symbols hit on adjacent reels from the leftmost side.

Stakes range from 0.25 to 100 per spin. The default RTP sits at 96%, though other settings of 94%, 90.5%, and 86% are used by some operators. Hit frequency is 25.5%, with medium to high volatility, and the max win reaches 3730x the bet. The feature set is busy in a good way, built around Wild Symbol, Gigablox, Free Spins, Gamble, Treasure Chest, Golden Bet, and Bonus Buy.

Symbols and Payouts in Notre-Dame Tales GigaBlox

Low pays are the suits of spades, hearts, clubs, and diamonds, paying 2x the bet for six of a kind. Premiums are Phoebus, Frollo, Esmeralda, and Quasimodo, worth 6x to 12x for a six-symbol hit. The Masked Man acts as the wild, substituting for pays and carrying its own line wins of 1.6x, 4x, 8x, and 20x for three to six respectively. The rose window serves as the scatter, and five or more on any spin triggers the bonus round.

Notre-Dame Tales GigaBlox Slot Bonus Features

The wild symbol substitutes for regular pays, helping tidy up lines when the grid gets busy. The Gigablox mechanic runs every spin with at least two linked reels, creating large symbols up to 4x4 in the base game. A 4x4 block counts as 16 individual symbols of that type, which can swing a screen fast. With Expanded Reels active in free spins, the grid grows to allow 6x6 GigaBlox and 40 paylines, which is where things can snowball.

Five or more scatters trigger free spins, awarding one spin per scatter plus 3 to 7 feature picks that last the whole bonus. Picks include Wild High, which turns one premium into wilds, Extra Wild for 1 to 2 guaranteed wilds each spin, Multiplier 2x on all wins, Expanded Reels with two extra rows, High Stack for a stacked premium, and Extra Free Spins adding 1 to 5 spins. The mix you land shapes how the round plays out.

On activation, I can gamble for extra spins via three cups, where two hold coins and one is empty. Each success adds one spin, up to eight, but hitting the empty cup ends the bonus at once. A Treasure Chest can land on reel 5 and always pays. In the base game it awards 2x to 500x cash or 5, 9, or 16 free spins. In free spins it gives 2x to 500x or 1, 2, 3, or 5 extra spins. Golden Bet costs +20% and grants one extra feature pick if the bonus triggers. Bonus Buy offers 150x for 5 to 16 spins with 3 to 7 picks, or 250x for 5 to 16 spins with 4 to 8 picks.

How to Win at Notre-Dame Tales GigaBlox Slot

Winning lines form from the left with three or more matching symbols, across 25 paylines in the base game and up to 40 during free spins. The shifting 4 to 6 rows change how the grid breathes, while linked reels feed GigaBlox every spin. Large blocks make it much easier to connect premiums, and when Expanded Reels come into play, those oversized symbols can cover serious ground, especially with Wild High or stacked premiums lending a hand.

I set a stake between 0.25 and 100, then use single spins or auto-spins if I am grinding. Golden Bet is worth toggling when I am chasing features, as the extra pick can change the tone of a bonus. The Treasure Chest on reel 5 is my favourite momentum swing, dropping cash hits or spinning me into free games. The whole loop feels about timing your features rather than forcing short stabs.

Notre-Dame Tales GigaBlox Slot RTP & Volatility

The default RTP is 96%, with alternative versions at 94%, 90.5%, and 86%. I always check the info page to see which one is live. Hit frequency is 25.5% and the volatility sits in the medium to high pocket, so I run sessions with a steady stake. The max win is 3730x the bet, so the ceiling is realistic rather than wild. Golden Bet lifts the cost per spin by 20% but keeps the paytable intact, trading coin-in for a stronger feature set.

The Final Thoughts on Notre-Dame Tales GigaBlox

For me, the charm lies in constant Gigablox pressure, then flipping the switch in free spins with a good spread of picks. Wild High, stacks, and a flat 2x multiplier can build a sturdy base, while Expanded Reels unlock the largest symbol sizes. The Treasure Chest feels like a proper bonus-sidekick, and the cup gamble adds a pinch of risk that suits the theme. It is a neat package when those parts line up.

If I am nitpicking, I would have liked a higher cap and a touch more RTP in some set-ups. Even so, the mechanic synergy holds up. I treat Notre-Dame Tales GigaBlox as a feature-led slot where smart pick outcomes drive the best spells. When the chest behaves, the picks land right, and the grid expands, it can swing a session in a few spins.
