The game Giganimals Gigablox, created by Yggdrasil, has a unique theme of farm animals attempting an alien planet invasion using flying saucers. The game mechanism involves Gigablox symbols that can fill the entire screen with the same symbol. Low-value symbols, represented by battery indicators, fill up UFO meters, leading to a bonus round where the triggering symbol turns wild. The game allows up to 4 low-value symbols to turn wild in a similar manner. The potential for a 20,000x win is present, but it might not be sufficient to keep the game from fading into obscurity.

On each spin, the reels can merge through the Gigablox mechanic to form large symbols. Despite their size, these Gigablox symbols still count as 1×1 symbols in win calculations. The most valuable alien symbols pay between 4 and 8 times your stake for 6 of a kind wins.

The Wild symbol can land anywhere and substitute for pay symbols, improving wins. Wilds can also pay up to 20x your stake for 6 wilds on the same payline. The game also features a Wild Surge feature that randomly turns at least 1 of the 4 low-value symbols into wilds. The game also provides between 5 and 24 free spins during the Collection Bonus Round, which can be gambled for more spins.

The game has not been notably successful, but there are plenty of ways to trigger the bonus round. The bonus round itself is not very exciting unless a few low-value symbols have been converted to wilds. While the 20,000x potential is surprisingly high, its realism is questionable.

Pros: <br>- Unique theme <br>- Multiple ways to trigger bonus round <br>- High win potential

Cons:<br>- Lack of excitement <br>- High potential win might not be realistic <br>- Low-value symbols may not be appealing.
