Moon Princess Extreme Slot Review – Demo, RTP & Features

Moon Princess Extreme is a high-volatility online slot from Play’n GO and the latest amplified entry in the long-running Moon Princess series.

Rather than replacing the familiar formula, this version takes the original 5×5 cluster-style gameplay and pushes the multiplier potential much further, with values climbing as high as x1,000 and a maximum win of 50,000x the bet.

The game keeps the series’ dreamy anime-inspired atmosphere, with Love, Star and Storm returning as the three princesses who influence gameplay through their individual Girl Power abilities. The 5×5 grid uses a modified cluster system where wins are formed by landing at least 3 matching symbols in a straight horizontal or vertical line.

Winning symbols disappear and the remaining symbols drop into the empty spaces, but unlike a standard cascade, new symbols do not refill the board.

This makes clearing the grid an important part of the gameplay, particularly because full clears can lead to significant rewards and, under the right conditions, the Free Spins feature.

Moon Princess Extreme has a highest RTP of 96.20%, although several lower configurations are available. Bets range from €0.10 to €100, while the game’s high volatility and 50,000x ceiling make this a much more aggressive version of the familiar Moon Princess setup.

Game Features

Moon Princess Extreme is played on a 5×5 grid. Winning combinations require at least 3 matching symbols arranged in a straight horizontal or vertical line. After a win, the matching symbols are removed and the remaining symbols drop into the newly created spaces.

Unlike many cascading slots, no fresh symbols are added from above to refill the grid. This means each successful win gradually reduces the number of symbols remaining on screen, creating the possibility of eventually clearing the board completely.

Wild Symbols

Wilds substitute for ordinary paying symbols and can help complete winning lines. Certain qualifying wins also leave Wild symbols behind in the grid.

When a 3-symbol winning line is removed, a Wild can appear in the central position of that combination. These Wilds then remain available for subsequent drops during the same sequence.

If the grid is completely cleared of regular symbols, leftover Wilds do not prevent the clear-grid condition from being achieved.

Win Multiplier

The win multiplier is one of the biggest upgrades in Moon Princess Extreme. It begins at x1 and increases by one step for each successful drop.

The multiplier can climb all the way to x1,000. During the base game, it remains active throughout the current cascade sequence but resets when the next paid spin begins.

In Free Spins, however, the multiplier becomes persistent and does not reset between spins, giving the feature significantly more long-term potential.

Girl Power

A Girl Power feature can activate randomly after a non-winning spin. The princess currently displayed beside the grid performs her unique ability before the next princess takes her place.

• Star adds 1 or 2 Wild symbols to random positions.
• Storm removes two sets of symbols from the grid.
• Love transforms one symbol set into another, potentially creating new winning combinations.

These powers are particularly useful when the grid is close to forming a win or nearing a complete clear.

Trinity Meter

Princess symbol wins charge the Trinity Meter.

The number of sections filled depends on the size of the winning Princess combination:

• 3 matching Princess symbols fill 1 section
• 4 matching Princess symbols fill 2 sections
• 5 matching Princess symbols fill 3 sections

Once all three sections are filled, the Trinity feature activates after the current sequence ends.

Trinity Feature

The Trinity feature awards a fresh spin where Love, Star and Storm all activate their Girl Powers one after another.

This can dramatically alter the grid by adding Wilds, removing symbol groups and transforming symbols. If the grid is completely cleared during Trinity, the Free Spins feature is triggered.

Free Spins

Before the Free Spins round begins, players choose one of the three Princesses.

Each choice provides a different starting number of spins and retrigger amount:

• Love – 4 initial spins, +4 on retrigger
• Star – 5 initial spins, +3 on retrigger
• Storm – 8 initial spins, +2 on retrigger

The selected Girl Power remains active throughout the feature and can trigger on non-winning spins. The biggest change is that the win multiplier no longer resets between spins. This allows it to keep increasing throughout the entire bonus and potentially reach the maximum x1,000 level.

Free Spins Retriggers

Filling the Trinity Meter during Free Spins awards additional spins. The number of spins depends on the selected Princess, with Love providing fewer starting spins but larger retriggers, while Storm provides more initial spins and smaller extensions.

The feature can continue until a maximum of 100 Free Spins has been awarded. This gives the persistent multiplier far more time to build if several retriggers occur.

Clear Grid Reward

Clearing every regular symbol from the grid awards a 20x bet prize. The reward is multiplied by the current active win multiplier.

For example, clearing the grid with a x50 multiplier would produce:

• 20x × 50 = 1,000x the bet

This becomes particularly powerful during Free Spins because the multiplier can remain elevated across multiple spins.

RTP and Volatility

Moon Princess Extreme has a highest RTP of 96.20%.

Alternative versions include:

• 94.20% / 91.20% / 87.20% / 84.20%

The difference between configurations is substantial, so checking which RTP version a casino is running is worthwhile.

The game has high volatility, meaning larger wins are expected to be less frequent but potentially more significant.

Betting ranges from €0.10 to €100 per spin.

50,000x Maximum Win

The maximum payout in Moon Princess Extreme is 50,000x the bet, making it the biggest headline win in the Moon Princess series so far.

The combination of persistent Free Spins multipliers, grid-clear rewards and repeated Girl Power interactions provides the main route towards the game’s larger theoretical payouts.
