Mermaid Riches
Mermaid Riches Free Slot Demo review
Mermaid Riches is an undersea-themed slot telling the story of Francis, who rescues a golden fish caught in a net on the shore and meets a mermaid princess. It was released on August 2, 2021, and you can play it right away with the free demo.
Why are the reels shaped like stairs?
It has a unique structure where reel 1 has 1 row, reel 2 has 2 rows, and so on up to reel 5, growing from 1 to 5 rows. On top of this are 20 paylines, with cascading creating chain wins. This kind of asymmetric reel is the experimental design you would expect from a PG Soft slot. Elements like the mermaid princess and golden scales bring out the underwater castle atmosphere well.
How do sticky wilds and multipliers work?
Sticky wild symbols lock onto the reels to help chain wins, and the win multiplier rises up to x10. While wilds hold their spot, combinations keep connecting, which makes it easy to build up the multiplier. When cascading continues with wilds locked in place, you can create multiple wins within the same spin, which nicely makes up for the weakness of the small grid layout.
What does it mean that the reels flip in free spins?
When you enter the free spins, the reels flip like a mirror. Reel 1 becomes 5 rows and reel 2 becomes 4 rows, while reel 4 turns into 2 rows and reel 5 into 1 row. As the official description says, you can go after bigger prizes on these flipped reels. The screen that was wider on the right in the base game becomes wider on the left in the free spins, and since paylines connect from the left, the way wins feel changes, which is part of the fun.
What about hit frequency and bet range?
Hit frequency is 28.44%, and bets range from €0.2 to €20. As a payline game, the combinations are simpler than in a ways game, so the flow is easy to understand. Volatility is medium too, so it is a good fit for running the demo for a long time to get a feel for the stepped reels. The 3,513x max win can be expected when sticky wilds and multipliers overlap.
What should I check first in the demo?
is 96.71%, volatility is medium, and the max win is 3,513x. Bonus buy is not available, so use the demo to see how often free spins arrive, and compare how the big left reels drive wins on the mirrored reels. It is also worth checking how high the max x10 multiplier can stack in the free spins.
