Nudge Wilds and Mirror Reels
The first feature of the Rainbow Jellyfish online slot is the wild. This substitutes for all regular symbols within the game to create or enhance winning paylines.
Hit four or six scatters on the Rainbow Jellyfish slot machine’s reels to receive 10 or 15 free spins respectively. The first and sixth reel mirror each other with the same symbols during each spin. This also applies to reels two and five, and reels three and four. Wilds that appear during the free spins round nudge up or down to cover the entire reel, thus increasing your chances of winning a prize.
