If you’ve ever heard of the snowball effect, Giga Jar is exactly that. Whenever a winning combination is formed, the symbols involved will disappear, making room for new ones. This can create additional winning combinations. Moreover, if you hit a non-winning cascade after two wins, you will trigger the Snowball Feature. The feature will place giant symbols (colossal symbols) on the reels. The giant symbols can fill up to 4x4 positions on the reels, potentially generating wins and prizes.
