Giganimals GigaBlox

Giganimals GigaBlox Slot Review

Four flying saucers hang down the left edge of the screen, each with a farm animal trapped behind domed glass: a pig, a rooster, a sheep and a boar, cabled into the reel frame. Below them, a mushroom forest glows orange against a burning pink sky, and a pale moon looms behind the bubble-letter logo. For all that colour, Giganimals GigaBlox runs on progress more than prizes: the four monsters pay on a tiered scale, and the four card symbols share one lower set of values.

Yggdrasil has built something denser than the cartoon suggests: a collection system feeding two separate free spins rounds and a gamble wheel on top, in the same block-symbol family as Hades Gigablox and Lucky Neko Gigablox. The stats are straightforward: 96.0% RTP, high volatility, a 6×4 grid with 40 fixed paylines, and a maximum win of 5,120x. The abductions, at least, are the point.

Base Game & Features

The grid runs six reels by four rows with 40 fixed paylines, and wins land roughly 24% of the time. Stakes run from 0.20 to 100 per spin. The reels themselves are the first feature: on any spin, single symbols can be replaced by Gigablox blocks.

Blocks come in three sizes and work in the base game and the bonuses alike. A 4×4 block covers sixteen payline positions at once, which is how a 40-line game produces wins worth caring about. Blocks can land on any reel, and a single spin can carry a mix of blocks and single symbols across the grid.

• 2×2 block: four payline positions
• 3×3 block: nine payline positions
• 4×4 block: sixteen payline positions

Four monster symbols sit above four card symbols in the paytable. The monsters come in red, green, blue and purple, and the low card symbols carry the same four colours, so each low symbol pairs with a spaceship meter.

Wild Surge

At random after a base game spin, the Wild Surge can convert one or more of the four low symbols into wilds, and any resulting wins are paid out. Wilds substitute for other symbols on a payline. Transformed symbols still count towards their collection meters, so a surge is never wasted even when it doesn’t connect.

The Collection Feature

Every win involving a low symbol feeds the spaceship meters on the left edge. One point is added for every section of reels the win passes through, and wilds don’t contribute. Points can arrive multiplied by anything from x2 to x5. Each of the four meters needs 480 symbols to fill.

A win stretching across more reels feeds more points in one go, which is where the Gigablox blocks earn their keep: a block-assisted win crossing several reel sections can move a meter in chunks rather than singles. Meters fill one symbol type at a time, and only that symbol’s meter moves when it wins.

The first session gets a helping hand. The Collection Boost starts the meters partway, so the earliest collection rounds arrive far sooner than the raw targets suggest:

• Red collection: starts at 336 of 480
• Purple collection: starts at 240 of 480
• Green collection: starts at 96 of 480
• Blue collection: starts at 48 of 480

After that, a full meter is a genuine grind, and that tension between the boost and the long haul is what the base game runs on.

Giganimals GigaBlox Free Spins & Bonuses

Collection Free Spins

Filling at least one meter in the base game awards between 5 and 20 free spins, with the first two boosted collections awarding 7. The round plays at the average bet size used during collection, so the stake you collected at matters, and the triggering symbol acts as a wild for the duration.

Remaining meters reset inside the round with a smaller target of 25. A meter that fills to maximum awards 2 extra free spins and turns its low symbol wild for the rest of the round, so a long collection round can end with most of the low pays replaced. Fill all four inside one round and every low symbol pays as a wild.

Scatter Free Spins

Five or more individual BONUS symbols in view trigger the second round, with Gigablox bonus symbols splitting into singles for the count. Each symbol awards one free spin, played at the triggering stake. Low wins still feed the meters, which reset here with a target of 16.

When both triggers land together, the game doesn’t make you choose: only the Collection round plays, and the scatter count is added to its spin total. It’s a tidy rule.

Free Spins Gamble

After free spins are awarded, the count can be gambled on a wheel with a cap of 24. Two options are offered: a low chance of moving to a lower number, or a high chance of moving to a higher one. Losing the gamble costs every free spin and ends the game.

The wheel runs at 100% RTP, so the maths is fair even when the outcome isn’t kind. The cap means there’s a defined best case: 24 spins, reached from a modest award by riding the high-chance option twice.

Bonus Buy

Three purchase options are available, and none of them touches the base game meter levels:

• A random amount of scatter free spins: 75x stake
• 24 scatter free spins: 150x stake
• 24 collection free spins with one low symbol set to wild: 250x stake

The 250x option is the closest thing to a guaranteed wild-heavy session on the menu, and it’s the one the game is clearly proudest of.

Our Honest Verdict

Overall Rating: 7.2/10

This is a slot you play to make something happen rather than to win something now. You feed the saucers, spin after spin, and the reason to choose it over a dozen brighter Yggdrasil games is that the feeding genuinely goes somewhere: meters visibly creep, and a filled meter always pays out.

The free spins structure is the best thing here. Because meters reset at 25 inside the round and each one filled turns its symbol wild, a single collection round that runs hot can end with half the paytable paying as wilds, and that’s where the 5,120x actually lives.

Long stretches between features feel empty. For patient players who enjoy watching a build come together, it rewards exactly that patience; anyone after quick bonus action will find the grind tedious. The saucers, at least, always come back for more.

Giganimals GigaBlox FAQs

• What is the RTP of Giganimals GigaBlox?

  96.0%.
• Is Giganimals GigaBlox high volatility?

  Yes, it’s a high volatility game, with a hit rate around 24% of spins.
• How do you trigger free spins in Giganimals GigaBlox?

  Two ways: fill at least one of the four collection meters in the base game for between 5 and 20 free spins, or land five or more individual BONUS symbols for one free spin per symbol. If both trigger on the same spin, only the Collection round plays, with its spin count increased by the number of scatters in view.
• How does the collection feature work in Giganimals GigaBlox?

  Any win involving one of the four low symbols adds points to that symbol’s spaceship meter, one point for every reel section the win passes through. Points can be multiplied by x2 to x5 before being added, and each meter needs 480 symbols to fill. Your first session starts the meters partway filled.
• What does the Free Spins Gamble do?

  After free spins are awarded you can gamble the count on a wheel, up to a maximum of 24 spins. There’s a low-risk option that can drop the number and a high-risk option that can raise it. Losing the gamble forfeits all free spins. The wheel runs at 100% RTP.
• Can you buy the bonus on Giganimals GigaBlox?

  Yes. A random amount of scatter free spins costs 75x stake, 24 scatter free spins cost 150x, and 24 collection free spins with one low symbol set to wild cost 250x. Buying doesn’t change your base game meter levels.
• What is the maximum win on Giganimals GigaBlox?

  5,120x your stake.
• Who makes Giganimals GigaBlox?

  Yggdrasil. It uses their Gigablox mechanic, where reels can carry 2×2, 3×3 or 4×4 blocks of symbols instead of single symbols.
