Pied Piper is a character from one ancient storytelling, a boy who was swift enough to lure the army of rats from the city into the sea with his panpipe, drowning them all, thus saving all city dwellers and their food stocks. Initially, Pied Piper was invented by Hans Christian Andersen – a dude who wrote many exciting stories for children and adult people. He lived from 1805 to 1875 years and was quite productive in his bibliography.
So, it is not a surprise that the slot has the ambiance of an old Danish city (as the author was Danish), and the background stays when you play. The Pied Piper is a Wild symbol – a nice-looking fellow dressed in purple according to the fashion of rich people of those times (though he was not rich originally).
It occupies an entire reel. Also, a little white mouse serves as Wild. A princess dressed in green is his beloved. There is also an old and experienced king with a very interesting beard and moustache. He has a Queen, which somehow is much younger than he is. The other symbols are also present: K, Q, A, J, 10 as the smallest, and a key, and a money sack as higher. The ‘Wild Mouse’ can be of two positions: she can stand straight or turned on the side a little.
If you collect the same symbols in one reel, filling it entirely, you receive a bonus. When a Pied Piper gets the entire reel, you receive Piper Respins. If you have Wild symbols (any of the present three types), they move one cell to the left during the free spins, eventually leaving the field.
When in the sequence of Piper Respins, at the last one, there is a chance to get a Mysterious Respin that triggers the Piper Respins again, giving you 5 of them. Thus, potentially (but not mathematically realistic), the sequence of Piper Respins can be infinite. Still, do not count too much on that – as math is a stubborn thing.
Three bonus scatters result in 10 respins. You have about 16.67% chance of adding one new Wild to your screen during each of such respins. The release was in January 2018.
