Play'n GO · 2022Overview
Moon Princess 100 is Play'n GO's magical-girl cluster-pays slot on a 5×5 grid. Land 5+ matching symbols anywhere and they explode; survivors tumble down and chain until no new matches form.
How it plays
Bet £0.20 to £100 per spin. Each cluster win triggers a tumble; multipliers build with each cascade, starting at 1x and climbing. The RTP sits at 96.2% — respectable for a high-volatility machine that can run dry for 50+ spins but pays hard when it connects.
The bonus round
Land 3+ scatter symbols to trigger free spins. During the bonus, multipliers persist across the entire feature and stack on wins. A single free spin retrigger resets your multiplier, but a hot tumble sequence can push payouts into five figures. The 50,000x max win is a tumble-chain theoretical ceiling.
Who it's for
High-volatility hunters who can sit through 80-spin droughts chasing a multiplier explosion at £1–£5 stakes and don't mind waiting for that cluster that pays the month.
Avoid if
You chase short winning streaks or play 20-spin sessions — Moon Princess 100 demands patience and a deep pocket.

No published cap exists, but typical feature runs plateau around 50–100x. A 200x+ tumble sequence is rare enough to be a viral moment.
Any cluster of 5+ matching symbols pays and tumbles. On a 5×5 grid, a five-symbol match at minimum bet (£0.20) often returns £0.40–£1.00.
