Bonus Features
Rainbow Princess isn’t limited to basic symbols and mechanics: the slot includes a series of features and bonuses that make every game more engaging.
Here’s a clear and concise overview of all the main features.
Super Cascade
When a winning combination forms, the corresponding symbols are removed from the grid and new symbols fall from above to fill the empty spaces. The cascades continue until new wins are created.
Magic Frame Multipliers
During a spin or cascade, if there is at least one winning cluster, Magic Frames with random multipliers (2x, 3x, 4x, 5x, 10x, 15x, 20x, 25x, 50x, or 100x) may appear. They remain on the screen for all cascades of the same spin and double in value each time they contribute to a new win. They are removed at the end of the cascades.
Aurora Gems
These gems can appear during cascades. Before payouts, they multiply all existing Magic Frame multipliers and are then removed. Only one Aurora Gem can appear at a time, with values ranging from 2x to 10x.
Tiara Treasure Bonus
Triggered by 3 FS Scatter symbols in the base game and awards 10 free spins.
During the bonus, the Magic Frames become adhesive and progressive, maintaining and increasing their value for the duration of the spins. Additional FS symbols can award additional free spins: 2 FS award +2 spins, 3 FS award +4 spins.
Make It Rainbow Bonus
Triggered by 4 FS Scatter symbols in the base game and awards 10 free spins. It retains the mechanics of Tiara Treasure but adds a rainbow bar that charges with each winning cluster.
When full, it distributes 3 to 5 wild symbols and then resets.
Again, 2 FS symbols add +2 free spins, and 3 FS symbols add +4 spins.
Hidden Epic Bonus Throne of Starlight
This is awarded with 5 FS Scatter symbols in the base game and awards 10 free spins. Each position on the grid starts with a progressive, sticky Magic Frame with a minimum value of 4x. FS symbols cannot appear in this mode.

Our Impressions of Rainbow Princess
We must admit that this sequel to the Cloud Princess slot impressed us with the variety and effectiveness of its features.
The Magic Frames are probably the most interesting element: not only do they remain on the screen for multiple cascades, but they double in value each time they contribute to a win, creating situations where even a seemingly ordinary spin can turn into something surprising.
The Aurora Gems add further positive tension, as they multiply all existing multipliers and can turn a round around in a matter of moments.
The Tiara Treasure and Make It Rainbow bonuses are also well-structured and keep the game engaging, especially with the possibility of accumulating extra spins.
Another plus is the 38.90% win rate. Translated for the less experienced, this means that, on average, more than one in three spins results in a win, even if it’s less than the bet. One aspect that may not be to everyone’s liking is the variety of RTPs offered by different operators and jurisdictions. Some versions feature lower percentages (even as low as 88.38%), which significantly reduce the potential long-term return.
