Burning Blox GigaBlox Slot Review
A fruit machine sits in a furnace: twisted gold framing the reels, flames licking the logo, giant grapes and cherries crowding in from the edges while embers drift through the red haze. Burning Blox GigaBlox is the rare retro slot where the paytable barely matters, because the diamond ladder does all the paying worth caring about. Jelly Entertainment runs it at 96.02% RTP, high volatility and 20 paylines on a 4×4 grid where symbols land as blocks up to 4×4, with stakes from 0.25 to 100. It sits alongside Big Benji’s Back WildWays and Diggin for Diamonds 2 in the studio’s jewel-and-flame corner.
Base Game & Features
Gigablox
Any symbol can land as a block of up to 4×4, occupying multiple cells at once, and blocks arrive on every spin. A block doesn’t count as one symbol; each of its cells counts individually, so a 3×3 Seven is nine sevens stacked together on the winlines.
That sizing is where the game’s texture comes from. A spin can bring a wall of plums filling the left half of the grid and leave the right half empty, and the next can scatter small symbols everywhere.
Two or more matching symbols on a winline pay, and only the highest win on each line counts. The hit rate sits around 25%, so roughly one spin in four connects somewhere. With high volatility on top, those connections skew small, and the pays below show exactly how small the floor is.
The Paytable
The pays are pure fruit-machine stock, scaled in multiples of the stake:
- Seven – 2: 0.08x, 3: 4x, 4: 8x, 5: 16x
- Bar – 3: 2x, 4: 4x, 5: 10x
- Cherries – 3: 1.6x, 4: 3.2x, 5: 8x
- Bells – 3: 0.8x, 4: 2.4x, 5: 4x
- Grapes / Lemon – 3: 0.4x, 4: 1.6x, 5: 3.2x
- Watermelon / Orange – 3: 0.2x, 4: 0.8x, 5: 2.4x
- Pear / Plum – 3: 0.16x, 4: 0.4x, 5: 2x
It’s a steep ladder. The Seven is the only symbol that pays for two, and it’s worth sixteen times what the bottom fruits pay for three. Below the cherries, every symbol pays less than the stake for a three-of-a-kind, which tells you where the base game’s money actually comes from: the blocks, not the lines.
Blocks are what put five-of-a-kind within reach. A full-height column of Bells counts as four bells on every winline it touches, and a 2×2 Bar cluster does the same work for that symbol. The top of the paytable is reachable in a way it never is when symbols arrive only one cell at a time.
The Diamond Wild
Diamonds are wild, and they carry their own prize ladder that pays regardless of paylines. Six or more in view in the base game and the ladder pays:
- 6+ Diamonds – 1.6x
- 8+ Diamonds – 4x
- 10+ Diamonds – 8x
- 12+ Diamonds – 16x
- 14+ Diamonds – 32x
- 16+ Diamonds – 160x
- 20+ Diamonds – 800x
It’s a scatter-style ladder bolted onto a wild symbol, and it changes what you watch for on every spin. A diamond block landing in one corner can carry four, nine or sixteen cells at once.
The jump from sixteen diamonds to twenty is the sharpest step on the board, and a screen filling with diamond blocks is the game’s signature image. Six diamonds alone pays 1.6x the stake; the same six arriving as two 2×2 blocks feel entirely different to chase.
Burning Blox GigaBlox Free Spins & Diamond Prizes
Free Spins
Five or more Bonus scatter symbols in view start the round. Each scatter converts to either one or two free spins, and the collective total is what you get.
That conversion is the whole variable. Five scatters can become as few as five spins or as many as ten, and a full screen of them can pay out 32. There’s no picker, no choice of volatility, just the count and the conversion.
The round plays to the diamond ladder’s strengths. Only four or more Diamonds are needed for a prize during free spins, and the ladder stretches higher at the top:
- 4+ Diamonds – 1.6x
- 6+ Diamonds – 4x
- 8+ Diamonds – 8x
- 10+ Diamonds – 16x
- 12+ Diamonds – 32x
- 14+ Diamonds – 160x
- 16+ Diamonds – 800x
- 20+ Diamonds – 2,000x
The floor dropping from six diamonds to four matters more than the ceiling rising. Sixteen cells is a full grid, so the 800x and 2,000x steps need diamond blocks stacking on blocks; four diamonds in view is a realistic target on a normal spin.
Retriggers are available throughout. Any Bonus symbol landing in view awards one or two more spins, so a round that starts small can keep feeding itself.
Bonus Buy
There’s a buy button in the base game. 60x the bet takes you straight into free spins, no scatter-chasing required.
That price holds at every stake, from the minimum to the top. What you’re buying is the conversion roll and the lowered diamond threshold; everything else about the round is the same one the scatters hand out.
Our Honest Verdict
Overall Rating: 7.2/10
This is a slow burn, and it’s built for people who like watching one idea catch fire. Every spin is really a diamond count: the fruit pays keep the lights on with small awards while you wait for the blocks to stack, and that counting rhythm is the reason to choose it over any prettier retro slot on the same shelf.
The free spins round is the best thing here, because dropping the diamond threshold to four turns a distant dream into a target you actually hit. The weakness is the base game’s own maths: with the best fruit paying 16x and everything south of the cherries paying pocket change, long stretches come in flat, and no amount of gold framing hides it.
It suits patient players who enjoy a ladder and can sit through the quiet spins; anyone chasing frequent mid-sized hits will find the furnace cold more often than they’d like. For the patient ones, when the diamonds finally stack to the ceiling, this old fruit machine burns as bright as anything Jelly have made.
