Here at Casinos.com, we pride ourselves not only on promoting the best online casinos, along with offering the best free slots, but also on our unseen work on sustainable development. Yes, all words that have been used previously in our other reviews will be used again. This means recycling all nouns and verbs and even repeating old jokes. This makes Rainbow Princess by Hacksaw Gaming one of the most sustainable slot reviews ever.
To help make this review, we have flown in our special guest by private jet and then driven them to our offices in a larger-than-needed vehicle. We will be joined by Sensei Jackpot, master of casino games, who specializes in Asian slots. How fortuitous that he should be from the same region. Sensei Jackpot will be playing Rainbow Princess for real money and telling us how he got on. After this, he will be driven back to the airport in a larger-than-needed car and flown back home by private jet.


Rainbow Princess is a medium volatility slot from which players will experience more balance between wins and losses. The RTP for this is calculated to reach up to 96.36%, which is standard. The maximum payout is 10,000x the betting price. Now, bets can range from $0.10 to $100, meaning the max jackpot is $1,000,000.
The gaming is hosted on a 5x6 layout, which requires five or more matching symbols to form a cluster for you to produce a win. Once you land a win, the Tumble mechanism activates and removes all winning symbols. These are replaced by new symbols that can automatically create a new cluster, which can then have a perpetual effect of repeated wins from a single spin.
During your game time, you will notice special symbols and features becoming activated, so let’s take a closer look at these in detail through the use of words.
Here's a detailed look at the features in the slot Rainbow Princess with the use of words.
The Rainbow Princess slot proved a bit too much for poor Sensei Jackpot, which is surprising given it comes with a medium volatility setting. That aside, the game pretty much gives you everything you expect of a Hacksaw Gaming slot. There is nothing new that this game offers except for the design element. Everyone has done the anime hot chick thing already, and now it’s the turn of Hacksaw Gaming. It’s a lackluster game, unless you have a kink for anime chicks. If you just want to take a look at the free slots demo game, no one will judge you, and the cookie settings on your device will certainly not lead to an influx of anime-style advertising.
