Bubble Bubble is a five reel and 50 pay line slot game released by Realtime Gaming. There is a top jackpot of 3000 coins and you can play for coin values as low as a penny and up to a quarter. Added features here include a bonus game, a wild symbol, a scatter symbol, a multiplier symbol, and free spins. The theme is paranormal activity and spooky ghosts.
The symbols used in Bubble Bubble include frogs, spell books, crystal balls, potions, black crows and cats. Winni the Witch is Wild and substitutes for all other symbols except for the scatter symbol. You can only find this symbol on the middle reel and when it does, it becomes an expanding wild and triples all wins. The Cauldron is the scatter symbol and when you get at least three you can choose to reveal a bonus prize, which could be the Great Ghosts feature. Here, you could see some Ghost wilds and get 20 free spins.
There is also a Wild Witches Feature that offers nine free games and a magical spell that Winni the Witch casts on one or two neighboring reels that can also turn wild! There is more, the Bewitched Feature awards 7 free spins with the witch frozen on the middle reel, for the duration of the bonus round. If you don't win at least 10x or more of the triggering bet, the Win-Win Feature comes into play awarding a guaranteed multiplier between 5x and 100x!
