How do the cascades and Clear the Grid work?
Winning symbols are removed and the rest fall down, but no new symbols drop in from above. Each win leaves a wild behind, which helps the next cascade. If a base spin clears the whole grid, you win 50x your stake. Highlighted positions on the grid also feed a win multiplier that builds during a spin and resets before the next base spin.
What are the Girl Power features?
One of the three princesses stands beside the grid, and her power can trigger during a spin:
- Love: changes one symbol type into another.
- Star: adds 1 or 2 wilds at random positions.
- Storm: removes symbol types from the grid to set off new cascades.
How does the Trinity spin work?
Wins with princess symbols fill the Trinity meter, and bigger princess wins fill more of it. When it is full, you get a Trinity spin in which Love, Star and Storm all use their powers. Clearing the grid during a Trinity spin awards another one, and the multiplier does not reset between them.
How does it compare with the original Moon Princess?
The core cascade and Clear the Grid idea is the same as Moon Princess (2017), but the original’s free spins round is gone, replaced by the Trinity spin, and the max win drops from 5,000x to 4,000x. Unlike the original, you can no longer pick your favourite princess. The series also includes Moon Princess 100 (2022) and Moon Princess: Christmas Kingdom (2021).
Tips for playing Moon Princess Trinity
- Princess symbols do double duty: they pay and fill the Trinity meter, so they matter more than their 3x top pay suggests.
- Clearing the grid is the key to both the 50x base prize and Trinity retriggers.
- Five RTP versions exist, down to 84.20%, so check the info screen for 96.20% before you play.
- Even the top symbol wins are small (5 wilds pay 5x), so the multiplier and Trinity spins carry the big results.
