Bubble Bubble Slot Game – Demo, RTP & Features

Bubble Bubble is a Halloween-themed slot machine from RTG, that incorporates some of the best-looking graphics, imagery, and animations we’ve seen from this developer.

It’s no surprise that the slot has quickly become one of the developer’s most famous – so keep reading to learn more about the game and find out what it offers!

The game’s backdrop features some kind of haunted house – and, in line with most of RTG’s slots, the overall gameplay and graphics are incredibly smooth-loading and easy on the eye – making for exciting gameplay.

The game is packed full of several exciting bonuses and features, and we’ll cover the details of these a little later on in this post. First of all, let’s take a look at the symbols on the reels.

As with most RTG Slots, you’ll find that the lower-paying symbols include playing card values – 10, Jack, Queen, King, and Ace – and the game’s higher-paying symbols are all game-specific symbols, including a Witch, a Potion, and a selection of Cauldrons.

Game Features

There are a few features to look forward to inside Bubble Bubble slot machine, and the first is a randomly-triggered feature, which sees the Witch turn the third reel fully wild. This happens regularly, and while it’s unlikely to lead to mega wins, it can help you make some lucrative 5-of-a-kind wins.

The main attraction of the slot is the free spins round, which is triggered by landing 3, 4, or 5 of the scatter symbols anywhere in view. Once you manage to do so, you’ll be awarded 7 free spins – and during the free spins, the third reel is wild for every spin.

There’s also another feature called the Wild Witches Feature, and this awards you with 9 free spins, during which each spin sees one or two reels turned fully wild each spin.
