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. <br><br>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. <br><br>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. <br><br>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. <br><br>Pros: <br>- Unique theme <br>- Multiple ways to trigger bonus round <br>- High win potential <br><br>Cons:<br>- Lack of excitement <br>- High potential win might not be realistic <br>- Low-value symbols may not be appealing.
