How the Game Plays

Bubble Bubble is a vibrant Halloween-themed slot from Rtg centered around the enchanting Winni the Witch. The action takes place on a 5x3 grid with 50 fixed paylines, set against a spooky, graveyard backdrop. Players win by landing matching symbols from left to right, with high-value icons including black cats, crows, and spellbooks. Winni herself appears as an expanding wild symbol on the middle reel; she substitutes for all other symbols and triples the payout for any winning combination she helps complete.

Free Spins Explained

Landing three or more Cauldron scatters triggers a selection screen where you choose one of the cauldrons to reveal one of three distinct features:

- Great Ghosts Feature: Grants 20 free spins. After any scatter payout, up to nine wild ghosts can fly onto the reels to replace other symbols.

- Wild Witches Feature: Awards 9 free spins. When Winni appears, she casts a spell to turn up to two additional reels completely wild.

- Bewitched Feature: Provides 7 free spins with Winni the Witch held as an expanded wild on the third reel for every spin.

Win-Win Feature Explained

Active during the Wild Witches free games, the Win-Win mechanic serves as a safety net for players. If the total win from the free spins round is less than or equal to 10x the triggering bet, the game awards a compensatory prize. If you earn nothing at all during the bonus, you are granted a special prize of 100x your total bet.
