Game review: Bubble Craze by IGT
It’s rare to see a slot machine break away from the tried-and-true reels and rows. IGT provides something interesting with their arcade and match-three inspired game: Bubble Craze slots.
With a simple matching scheme, it throws away complicated paylines and bonus systems. Multipliers, transformers and an exciting free spin round spice up the game, but the core gameplay is meant to be fun, relaxing and calming for new players or players who want something a little different.
While the Bubble Craze slot machine doesn’t have the most complicated design, it does have nice, practical graphics that work well with the mechanics. The game is just a neon-light interface with 19 bubbles floating in the center of the screen in eight different colors.
The background is a faded out version of the game with more fuzzy bubbles and water. While the designs aren’t too exciting, it’s easy to see matches and quickly read the board. The animations are also fairly well done. Each round starts with the previous set of bubbles popping to make room for the new set that rises from the bottom of the screen.
The sound design is fairly nice and fits in with the calming nature of the game. During standard play, the music is easy-going, ocean-style music that feels a little meditative. When the wins start stacking up, it switches to a faster pace and a stronger beat to match the excitement. It’s nothing too new, but the sound is perfect for settling in and watching bubbles pop.

Bubble Craze: Core gameplay
Bubble Craze features a nontraditional system, with 19 independent spaces on the game board. Since there are no paylines, players have to play a full 50 credit bet for each spin. If at least four bubbles of the same color are touching, then it’s a win.
It’s possible for more than one set of four to appear in one game, and the rewards do increase as the number of matching bubbles in a set increases.
A full set of 19 silver bubbles nets the 10,000x jackpot. There are no wilds available, but there are a few special bubbles.
Special-transform bubbles can appear in any batch. Once the bubbles settle, any transformed bubbles pop and change all the bubbles adjacent to them to match their color. Depending on where the transformer is, it can easily set up a big payout.
There are also multiplier bubbles available. Bubbles marked with 2x or 5x multipliers can spawn in the set, and if one is included in a winning match it multiplies the payout.
Playing the game can be a slightly uneven experience. The 50 credit bet is fairly expensive, with only the highest paying set of four offering a profitable return.
The bottom tier of bubbles actually needs a set of eight to break even. These standard wins are mostly there to slow down losses while players are waiting for a big win to swing things back.
The real winnings rely on a good transform bubble, a good multiplier or a few big wins in the free spin round.
The free spins bonus feature
Bubble Craze features a slight variation on a typical free spin bonus round. The center top, middle and bottom bubbles in the game can occasionally be filled with a special bonus symbol.
If all three symbols appear, then they link up and award the player with a set of five free spins.
They’re not just spins though. This separate round uses a special set of potential bubbles that is salted with extra multipliers and transform bubbles.
Each spin is also guaranteed to have at least one winning set in it. It’s a short bonus round, but it’s possible to really strike it big with the loaded board.
Overview
Bubble Craze may not be perfect for every player, but anyone looking for a more relaxing game should enjoy it. There’s something peaceful about just watching the bubbles pop and hoping that the next set of colors lines up well.

The simple graphics and soft music almost make it a little zen. Never having a washout on a series of free spins is nice, too. Players looking for something flashier or with a more involved bonus round may be disappointed.
The line between calm and boring can be thin, after all. Anyone looking for a refreshing change of pace should give it a shot though.
Bubble Bubble slot is a new surrealistic looking machine developed by Real Time Gaming (RTG). The game is stacked with multiple bonus features, expanding wilds and multipliers.
Together with other recent releases, like the Pirate Isle and Orc vs. Elf slots, it seems that RTG managed to break away from the regular simple looking slots and catch up with the rest of the gambling world.
Design & Symbols
For many, Bubble Bubble reminds the funny computer game from the 90s. Well, the Bubble Bubble slot has nothing to do with the original game. It’s a Halloween themed slot, with Witches, Ghosts and other scary and surreal symbols.
Winni the Witch is the wild symbols of the game. It appears on reel 3 as an expanding wild, covering the whole reel. When in a winning combination it triples your payouts. The Cauldron is the scatter symbol and the one that triggers the bonus features.
The number of lines is fixed on 50 and the bet size varies from $0.50 and up to $250, which is good for the those of us looking for high limit slots and casinos.
Free Spins Bonus Features
Bubble Bubble offers three different bonus games: Wild Witches, Great Ghosts and Bewitched. They are all triggered the same way by getting 3 scattered Cauldrons anywhere on the reels.
Bubble Bubble Bonus Features
As you will see below, the features allow you to control the volatility of the slot. The Great Ghosts gives you the highest number of free spins, but usually with lower payouts. Wild Witches can be the most rewarding bonus, but you have only 7 free spins to make it work.
The Great Ghosts
The Great Ghosts bonus will get you 20 free spins. During the game additional wild symbol will be added on the reels – the Ghost wild. Every time a scatter symbol appears on the reels, Ghosts wilds will fly in and land on various positions. There can be up to 9 of those.
Wild Witches
With Wild Witches you will get 9 free spins. The special part is that every time Winni the Witch appears on the reels, she will expand to 2 additional reels, making 3 reels completely wild. Wild Witches bonus also has a Win-Win feature, which insures a win of at least x10 times your bet. If you are “lucky” not to win anything during the free spins, you will be given x100 of your original bet.
Bewitched
Best Bonus Slot Machines
Bewitched will give you 7 free spins with sticky wild on reel 3 for as long as the feature is active.
Bubble Bubble Slot – Bottom Line
Personally, I find the design of this slot a bit chaotic, but still I enjoy playing this game and glad to see RTG develop new and different looking slots. Three different bonus features with expanding wilds are fun and can be really rewarding.
