Aztec GigaBlox Slot Review
A stepped pyramid breaks the haze on the horizon and the reel window glints gold and emerald, but the real treasure in this jungle isn’t the scenery: it’s that a single wild can sweep every prize off the board in one spin. That collection mechanic, not the oversized symbols everyone comes for, is what Aztec GigaBlox is actually built around. ReelPlay‘s temple runs a 6×4 grid with 40 paylines, medium-high volatility, a 10,245x ceiling on the max win and 94.0% RTP in the regular game.
The format’s whole promise sits in one rule: every spin lands at least one oversized symbol. It gives the studio’s usual big-grid spectacle, seen in titles like Atlantis 10K Ways and Hercules 10K Ways, a home in the temple ruins. It’s the prize collecting underneath all that gold that decides whether the expedition pays.
Base Game & Features
Wins pay left to right on adjacent reels from the leftmost, and only positions containing the winning symbol count towards that symbol’s win. Only the highest combination is paid on each active line. Coinciding wins on different lines are added together, and all wins are multiplied by the total bet.
The base bet works out as the total bet divided by 40, which matters once the Buy Bonus enters the picture. Otherwise it’s a conventional line setup underneath an unconventional reel set. You pick a total bet and the game plays all 40 lines.
The WILD substitutes for every symbol except the SCATTER and the PRIZE symbol, and it pays for itself too: 10x for six, 2.5x for five, 1x for four and 0.5x for three. The SCATTER appears only in the base game and exists purely to trigger the feature.
Just under a quarter of spins, 24.63%, return something. That’s a fair strike rate for a medium-high game. The Gigablox guarantee does its part: with a guaranteed oversized symbol on every spin, near-misses at least look like possibilities.
Gigablox
Gigablox are oversized symbols that occupy the reels in 2×2 up to 4×4 formations while functioning as individual symbols. Any symbol can land as one, including the WILD, PRIZE and SCATTER. Every spin is guaranteed at least one Gigablox reel, and PRIZE and WILD Gigablox always land wholly within the reel display, so a big block never half-disappears off the edge.
On a 40-line game the effect is real: a 4×4 block covers sixteen positions, which can complete lines across several rows at once. The guarantee means no spin is ever entirely small, even when it pays nothing.
Prize Symbols
Each PRIZE symbol displays a random prize or bonus prize. Whenever a WILD lands, it collects the prizes from all PRIZE symbols on the reels, whatever they show. If the PRIZE is a Gigablox, its value is multiplied by the reel width of the block. If the WILD is a Gigablox, everything it collects is multiplied by the wild’s own reel width.
The reel-width multipliers are where the sums get interesting. A PRIZE Gigablox two reels wide pays double the value shown on it; three reels wide pays triple. Put a wide WILD Gigablox next to a wide PRIZE Gigablox and the two multipliers compound, which is the route from a modest prize list to a serious one.
The bonus prizes sit on a four-step ladder, shown on the meters beside the reels, and none of them are progressive:
- Grand – 1,000x the total bet
- Major – 250x the total bet
- Minor – 50x the total bet
- Mini – 10x the total bet
Mini and Minor can be awarded more than once in a single game round, while Grand and Major appear no more than once each. Non-bonus prizes run as multiples of the total bet across 1x, 1.25x, 1.5x, 1.75x, 2x, 2.5x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 12x, 15x, 20x, 25x, 30x, 75x and 100x.
The figures shown over PRIZE symbols are already multiplied by the total bet, so what you see floating above the block is what a wild would collect. A single wild sweeping the whole board in one spin is this game’s biggest base-game moment.
Aztec GigaBlox Free Spins & Bonus Features
Free Spins
Free Spins trigger when 5 or more SCATTER symbols appear, awarding one free spin per scatter landed. Land nine scatters and you play nine spins. Land five and you play five, so the size of the trigger directly sets the length of the round.
Every free spin contains at least one WILD symbol, which matters more than it sounds: with a wild guaranteed on every spin, the prize-collecting mechanic is always live during the round. Scatters, meanwhile, exist only in the base game, so there’s nothing left to land during the feature itself.
Free Spins can’t be retriggered, and they play at the same lines and bet as the triggering spin. There’s no multiplier escalation or mode selection; the round is simply the base game with a wild on every spin. It runs to its fixed length and hands you back to the jungle.
Buy Bonus
Where the option is available, the Buy Bonus purchases the Free Spins feature outright. The purchased spin always lands 5 or more scatters, so the round you buy is a full round, scaled to whatever the scatter count turns out to be:
- Cost: Base Bet x 2,400
- Played at: Base Bet x 40
- Guarantee: a spin that always lands 5 or more SCATTER symbols
- Buy Bonus RTP: 94.6%
The option isn’t offered in every jurisdiction, so it’s worth checking the machine you’re at before budgeting around it. Where it exists, the 94.6% return edges the regular game’s 94.0%.
Our Honest Verdict
Overall Rating: 6.9/10
This is a game of waiting in a very pretty jungle. Every spin gives you something oversized to look at, and every so often a wild walks through and takes everything that isn’t nailed down – that moment, not the feature round, is the reason to be here. The pyramid on the horizon is a promise, and the game is patient about keeping it.
Its strength is that the collecting never switches off. Whether it’s the base game or a free spin, the wild-and-prize pairing is always live, and the reel-width multipliers reward exactly the boards you most want to see. Its weakness is the arithmetic: a 94.0% return is thin for a medium-high game, and a feature round with no retrigger and no escalation can’t make up the difference.
That leaves it as a game for players who like a steady build and don’t need the bonus round to be the whole story – anyone chasing long, escalating feature runs will run out of temple before they run out of patience. For the rest, the gold in the vines is real; you just have to dig for it at the pyramid’s pace.
