Rainbow Princess Slot – Free Demo

Three bonuses hide behind the FS symbols

For a while Hacksaw Gaming enjoyed quite a fine stretch with powerful cluster slots like Le King and Le Cowboy. These were games that caught the eye of casino streamers and casual players alike. Since then the inventive concepts seem to have run thin, and the identical mathematical model appears to have been on a copy and paste, which is why Hacksaw Gaming is in urgent need of a fresh powerful slot, especially with so many up and coming slot suppliers taking large portions of the iGaming market. Three separate bonus rounds sit behind the FS symbols here, alongside a bonus buy and a FeatureSpins mode.

Could Hacksaw Gaming's Rainbow Princess be that single game that compensates for the generic games lately released? One bonus is awarded for 3 FS symbols landing together, one for 4 of them and one for 5. Sounds encouraging. But I'll see. Feature buys are allowed to cost more than the 100.00 top bet.

Throughout the game, Magic Frame Multipliers unlock the huge wins when they land on positions that are part of a winning cluster, and in the Make It Rainbow bonus every winning cluster is added to the Rainbow Rush Bar. The four bonus rounds I saw paid between 13.0x and 24.0x the stake. It is shown beside the reels.

The FeatureSpins switch beside the buy button

Created by provider Hacksaw Gaming, Rainbow Princess is a 6-reel, 5-row online slot with cluster pays and a 96.36% RTP that's playable on all devices from 0.10 to 100.00. Beside the BUY BONUS button there is a FeatureSpins™ option, where each spin guarantees certain features at a cost set by the current bet level and stays active until you press DISABLE. It rests at 3 out of 5 on the volatility scale. One of those settings, MAGIC MODE FEATURESPINS™, runs with FS symbols removed from the reels entirely, so no bonus can trigger while it is on.

Five connecting symbols, anywhere on the grid

Clusters are shaped by 5 or more connecting matching symbols anywhere on the grid, and there is also a wild symbol present. Only the highest win per winning way is paid. It stands in for all paytable symbols. Across my run 125 of the 415 spins paid something, and 70 of those returned less than the 2.00 stake.

The max win with cluster pays is 10,000 times the bet. Reaching it ends the round on the spot, and any free spins or features still owed are discarded. I have to admit that this is rather decent, especially since it applies in every game mode, and on top of this add the Sticky Progressive multipliers in the bonus...hallelujah. Nothing near it showed up for me, where the best single spin returned 35.0x the stake on spin 341.

What a winning cluster takes with it

When a cluster wins, Super Cascades strips every ordinary symbol of the winning kind from the grid, not just the cluster itself. New symbols tumble in, and this repeats until no fresh win forms. An Aurora Gem is removed as soon as it has applied its multiplier.

Magic Frame Multipliers emerge at random positions during a spin or cascade. A Frame displays an adding multiplier and only activates if its position ends up inside a winning cluster. They do so only when at least one winning cluster is on the grid, and several Frames in one cluster add together first, then multiply the win. My largest spin of the session, spin 341, paid 70.00 at a 2.00 stake. Values begin at 2x, 3x, 4x, 5x, 10x, 15x, 20x, 25x, 50x and 100x. Frames hold their positions through the cascades of a spin. A Frame's value doubles after each win it takes part in, applying from the next cascade, and all Frames vanish at the close of the spin. The rules set no ceiling on how far a Sticky Progressive value can keep doubling. Landing during cascades, one at a time, Aurora Gems multiply every Magic Frame Multiplier on the grid by x2 to x10 before any win is paid. Bonus rounds accounted for 27% of everything I won.

1 / 3

3 FS symbols landing together trigger Tiara Treasure and award 10 free spins, while 4 FS symbols award Make It Rainbow, which adds the Rainbow Rush Bar. All three bonuses start from the same 10 free spins. It is filled by each winning cluster in proportion to its size, dropping 3 to 5 Wilds onto the grid when full. The bar then resets and keeps filling for as long as free spins and wins remain. 5 FS symbols award Throne of Starlight. There every position begins with a Sticky Progressive Frame of at least 4x, and in all three bonuses the Magic Frame Multipliers turn Sticky Progressive, retaining their positions and values across spins and rising for the rest of the round. In the first two rounds, 2 extra FS symbols landing together add 2 free spins and 3 of them add 4.

Our Minty Verdict: The multipliers only compound inside a round, and rounds were rare — four in 415 spins, 519.80 back from 830.00 staked. The 10,000x needs the sticky version of a mechanic that wipes itself off the grid every spin in the base game.

Four bonuses in 415 spins

I have to concede that this is an ambitious attempt and the production is of very high calibre. It certainly stands out from the studio's more routine releases. Four bonuses in 415 spins works out at roughly one every hundred.

The graphics are immediately recognizable as the trademark Hacksaw art I'm accustomed to, which is not a bad thing. The visual effects are really busy and all in all, it is a very loud production. The longest gap without any win at all was 13 spins, ending on spin 231.

These type of slots that permit sticky multipliers to accumulate in the bonus have proved to be rather popular. Here those sticky values grow through Aurora Gems as well as through wins. It has been executed well in this game too, though it should be noted however that in Throne of Starlight the FS symbols cannot land at all. This means the biggest of the three bonuses is also the one round you can never extend. My own four rounds came on spins 127, 157, 232 and 344, with gaps of 30, 75 and 112 spins between them.

My own 415 spins at 2.00 were a good deal less generous, returning 519.80 of the 830.00 staked, or 62.6%, with the balance never once creeping back above the 5,000.00 I began with, and four bonus rounds paid 142.00 between them. The low point along the way was 4,655.40, and the run closed at 4,689.80. Only time will tell if Rainbow Princess is to be adopted by all the slot players out there.
