Bubble Bubble Slot is currently available only in free play mode in your country.

Bubble Bubble is a video slot powered by Real Time Gaming software with 5 reels and 50 pay-lines. This is Halloween-themed slot packed with Halloween symbols such as witches, black cats, book of spells and more. The feature-rich masterpiece with a cartoon look. The reels are set between two concrete gate columns against the background of a dark and gloomy cemetery. Give this scary looking slot a spin here for free or visit any of the Real Time Gaming Casinos to play for real money.

Before you visit the cemetery, you should set your betting range the way it suits you the most. "Bet" arrows are used to set the coins size which ranges from 0.50 to 250. "Spin" will set the reels in motion, and you use "Autoplay" option when you wish to turn the reels automatically without any interruption. "Speed" is used to set how fast the reels will turn, and you have 3 gears.

Winnie the Witch is the Wild symbol in the game, and it appears on reel 3 during base game. Winnie can change for all the symbols except for the Scatter. This is an expanding Wild, which means that when a Wild hits the reels it will expand and cover the whole reel. If Winnie is involved in a winning combo then your wins will be tripled.

The Scatter symbol is a boiling Cauldron, and it can form scatter wins, all of which are multiplied by total bet. If you land 3 or more scatters, you need to touch a triggering Cauldron Scatter, and you will be randomly awarded with one of the three features: Wild Witches feature, Great Ghosts feature and Bewitched feature.

Great Ghost feature awards you 20 Free Spins, and up to 9 Wild Ghosts will land onto the reels after any scatter win is paid. Wild Ghosts can substitute for all the symbols except for the scatter, and they appear only during this feature. You can re-trigger this feature.

Wild Witches feature award you with 9 Free Spins, and whenever Winnie the Witch appears on the reels, she will cast a spell on 1 or 2 other reels. Reels struck by the spell are turned into Winnie Wild before pays are awarded. The feature can be re-triggered, with re-triggering scatters counted before any spells were cast.

Bewitched feature awards you with 7 Free Spins, and Winnie the Witch will cover the middle reel. This feature can be retriggered, as well as the other two.

Win-Win feature is active during Wild Witches feature. This feature, will award bonus if the overall win from the Wild Witches feature is 10x the triggering bet or less. This of course excludes the triggering bet. No win awards a prize of 100x bet.

Bubble Bubble slot was a good slot game that RTG developed and I insisted for it even if it’s not the season of Halloween. The reason is that it’s great for it’s a 50 pay lines and 5 reels and while betting, the winnings were great and you can credit bet the $0.01 up to the $1.00 credits. Just for fun there’s one time that I made a bet of $1 for every line $40 per spin, while spinning I just hit the wild bonus and won something $900 such encounter is lucky decision for me.

The graphics is good and I love the feature of it the free spins and bonus game. The game itself is not that scary because of the lovely witch depicted from the slot wild symbol! I’m so lively when I see the wild witch wandering from the slot pay lines! The delicate design of the Bubble Bubble’s characters background are made for the common horror stories of graveyard, bone hands, scary owls and spider webs with the symbols of skulls, cauldron magical ball to name a few.

There was always a good vibes of getting the bonus feature where if I always got it there is a magical word of “feature triggered” and was exciting! First is the ghost feature the second bonus is the witches feature and the last is the bewitched feature. This will be depends on what type of bonus then there is a cumulative free spins for every type all of them was a great time of bonus experience. I didn’t get loses from these type of bonuses whether I wager low or high $1.20-$10 the slot Bubble Bubble did have a backup plan for the losses and that was the greatest thing about this slot that RTG created. The feature is called win win feature you will win even if you lose and that’s almost 100x of the bet depending on the win awarded.

Bubble Bubble is 50 paylines video slot from RTG software company. I played this game only once, with bonus free chips. I never tried it with my own money. The only reason is because I don’t like how my gameplay session ended at it.

The main game is ok, but while I was playing it it was so boring. I never won any decent winning combination, most of the time there were empty spins or some pennies back in return – almost the same as my bet or even lower than that. And I didn’t expect that at slot with 50 paylines.

Otherwise here are three different free spins features. The Great Ghosts feature gives you 20 free spins – during this feature additional wild symbols will be added on the reels. Wild witches is next feature which offer you 9 free spins. Here are expanding wild symbols. When Winni the Witch appears on the reels, she will expand to 2 additional 2 reels, making up to 3 reels completely wild. The last feature is Bewitched – 7 free spins with sticky wild on reel 3 for as long as the feature is active.

The last feature looks good, but there is only reel 3 with sticky wilds. I don’t like that very much. I think Wild witches is the best feature here – for me, which I would wish to get. But hey… I got it and I was disappointed. I won from it only around x20 bet, and I expected so much more from it. During those 9 free spins I got once two wild reels - 4 and 5. But there were no any winning combinations, I was so disappointed and angry the same time.

I think this game could be fun to play it sometimes. But I had bad experience with it and I think I will not play it again in future. I will rate it with 7 stars because of three different free spins features!

At first glance "Bubble Bubble" is a slot that does not attract enough and this is not because it has a very dark theme or because most of its symbols are represented with sinister or repulsive images, I rather think the reason is that their symbols look crammed and a feeling of saturation and disorder is created to some unpleasant point, however it must be understood that it is a slot inspired on Halloween and we cannot expect just cute characters, though I admit the witch looks pretty nice and attractive.

However all the ugly of this slot ends in its appearance since as far as I'm concerned, I was not so amused with a slot manufactured by "Real Time Gaming - RTG" since T-Rex; I think the paytable is quite fair and although sometimes they happen long streaks of dead spins, its special feature is strong enough to keep the interest of the player because it is not so difficult to be triggered and also the potential profit offered is not at all negligible; this feature is triggered when a cauldron appears at least on each of the first 3 reels with the advantage that the wild symbol is set to replace this special symbol and in the practice we see the great importance of this is this way; once activated the feature we click on one of the cauldrons to see how they will be our free spins, there are 3 different possibilities:

- Wild Witches Feature, which provides 9 free spins, tripling profits and randomly an additional wild reel on different position than reel 3 will be given to you; my best hit with this feature was when I got a wild reel on reel 3 and the other on reel 1 with an approximate winning of 50x my total bet in just one shot, it was great.

- Great Ghost Feature, that awards 20 free spins and then 1, 2 or 3 ghosts can cross the reels to settle on any square and turn it into wild symbol; here I have not made great gains in a single spin but total profits generally are also good.

- Bewitched Feature which gives 7 free games and for all spins the reel 3 is wild and all winnings are tripled; I personally managed to re-trigger this round for two additional times because to do it you just need two cauldrons on reels 1 and 2.

Additionally sometimes when our profits on some of the rounds are very small, as a guarantee, it is triggered the feature “Win to Win” at the end of the round and it multiplies your total bet by 5x or more and adds this value to the total of your winnings during the respective round, a very generous gesture in my opinion.

In short, now that I know it, this game is a very good candidate to become my slot RTG favorite, I've played it several times and have always managed to come out well; the game itself does not look very nice but I still think it has all the characteristics of a good slot, I recommend it.
