Bubble Bubble Slots has become one of RTG’s most popular and admired slots. Its engrossing atmosphere, exquisite animation and creepy, impactful visual style can leave plenty of positive emotions in every player. The background of the reels depicts a graveyard. The night sky has a filthy shade of dark green, the black branches of the naked trees cut into it and there is an extremely unnerving silhouette of an owl, which has two big, lifeless yellow eyes. The symbols on the reels are equally impressive. They are all depicted in golden rings and every single one of them features an overwhelming amount of detail – the drawing style is cartoonish but highly effective.
The gameplay involves 5 reels, 3 rows and 50 paylines. Coin sizes start at 1 cent and can be as high as 25 cents. The maximum possible bet for a single spin is 12 dollars and 50 cents. The speed of the spin can be adjusted and the reels can be stopped at a time of the player’s choosing. What will really bring the big bucks to gamblers is the collection of excellent bonus features, which involves profitable symbols like a wild and a scatter, a giant paytable and 4 different bonus games, which can deliver big prizes in their own unique ways.
The black cat is the highest paying symbol of the game, awarding 6, 33, 333 and 1000 credits. The crow offers 3, 33, 333 and 1000 credits. The frog brings 3, 12, 150 and 333 credits. The pumpkin and the Spell book grant 3, 6, 60 and 333 credits. The other symbols are in possession of 3 winning combinations that include from 3 to 5 matching symbols. The crystal ball, the potion and the disgusting ingredients symbols give 5, 33 and 150 credits. The candles, the skull and the spider provide gamblers with 5, 20 and 99 credits. The scatter of the game also delivers payouts of its own – it is the Cauldron and its rewards are actually multipliers increasing the total bet – 2 times for 2 symbols, 3 times for 3 symbols, 6 times for 4 symbols and 33 times for 5 symbols.
The wild of the game is Winni the Witch – a very attractive lady in scarce black leather outfit, sitting on a gravestone. It can replace the rest of the symbols in the game including the scatter in order to form combinations. The wild can only make an appearance on the third reel but when it does show up it will expand to cover the entire reel. When the wild takes part in a winning combination, the payouts of it will be multiplied by 3. At least 3 scatters will activate one of three features – Wild Witches Feature, Great Ghosts Feature and Bewitched Feature. One of the triggering scatters will have to be touched in order for a bonus round to be revealed and started.
The Great Chosts Feature provides members with 20 free spins. Up to 9 wild ghosts (symbols that make an appearance only in this feature) will show up on the reels. They can substitute the other symbols in the game, except for the scatter. The Wild Witches Feature awards 9 free spins. When wilds appear on the reels they will go on to fully cover them. During the Bewitched Feature players will be able to profit from 7 free spins and a wild symbol that appears on the middle reel. The Win-Win feature is not one of the three but it can be activated when the prizes from one of the three is not big enough (10 times the triggering bet or less), more than making up for the underwhelming bonus round experience through great prizes.
Bubble Bubble Slots is one of the best online games with a dark, witch-related theme. It doesn’t just feature an impressive appearance but also an extraordinary gameplay with countless profitable symbols and a huge number of bonus games.
