When Play’n GO revisited its most-played anime franchise in 2023, the brief was straightforward: keep the cluster engine that made the original a modern classic and rebuild the ceiling. Moon Princess 100 is the result, and after logging a great many sessions on it, we can tell you exactly where it sits in the studio’s catalogue.

Moon Princess 100 is the third major entry in a lineage that began with the original Moon Princess in 2017 and continued through Moon Princess Trinity. Mechanically it is a cluster-pays slot: symbols pay when enough of a kind connect on the 5×5 board, rather than along paylines. The “100” in the title is not decorative. It signals the two headline numbers Play’n GO pushed upward for this edition — a multiplier that now climbs to 100x, and a free spins pool that can reach 100 spins, versus the far tighter limits of the earlier releases.
The three princesses — Love, Star and Storm — remain the structural heart of the game, each governing a colour and its own escalating win multiplier. That continuity is deliberate. Play’n GO has kept the identity intact while raising the max win to 15,000x, roughly triple the original. For a returning player it feels familiar; for a newcomer it plays like a well-tuned, high-variance grid slot.
Set your stake anywhere from £0.20 to £100 and spin. Matching symbols that form a cluster are removed, credited, and replaced by new symbols dropping in from above — this is the Winning Drop cascade. A single spin can therefore resolve into a chain of consecutive wins before the board finally settles. Each princess’s multiplier increments as you clear symbols of her colour, and those multipliers apply to the wins they help create.
When a spin ends without a win, one of the three princesses may trigger her Girl Power modifier at random — converting one symbol type to another, destroying a symbol, or adding wilds. This is the game’s safety net against dead spins and a key reason the base game rarely feels static.
Clearing the entire grid triggers Trinity, and repeated full clears build toward the free spins round. When you enter it, you select a princess: Love, Star or Storm, awarding 4, 5 or 8 free spins respectively. The trade-off is deliberate — fewer spins with a higher starting multiplier, or more spins that build gradually. We’d encourage you to confirm the exact multiplier behaviour in the game’s info screen, as presentation can differ by operator build.
The free spins are where the 15,000x ceiling becomes plausible. Multipliers carry and compound across the round, and with the cap lifted to 100x, a sequence of full clears during Storm’s eight spins is the realistic route to the biggest results. It is, by design, a top-heavy distribution: the mode delivers infrequently but with genuine scale, which is consistent with the 8/10 volatility rating.
Visually this is polished, mature anime — clean vector art, expressive character animations and a magical-girl aesthetic that Play’n GO has refined over three titles. The soundtrack swells convincingly during cascades. It is not a reinvention of the look, and it doesn’t need to be; the presentation is a known quantity that has aged well.
Moon Princess 100 is the definitive version of a slot that was already a benchmark for the cluster genre. Play’n GO raised the ceiling where it mattered without breaking what worked. It rewards patience and a stake sized for high variance. Confirm the RTP your operator is serving, and you have one of the better-engineered grid slots on the market.

The default return to player is 96.20%. Play’n GO also supplies lower-RTP builds (as low as roughly 84%), so always verify the figure in the game’s info screen at your chosen casino.
15,000x your stake — around three times the original Moon Princess and reached primarily through compounding multipliers in the free spins.
High. Play’n GO rates it 8 out of 10, so expect variance and size your bets for extended sessions.
Full grid clears build toward the round. On entry you pick Love, Star or Storm for 4, 5 or 8 free spins, trading spin count against multiplier behaviour.
No. It shares the cluster engine and three-princess structure but lifts the multiplier cap to 100x, free spins to 100 and max win to 15,000x.
