Gone are the days when big bands and swing music was heard everywhere, but still the legends of yesteryear remain and influence us today. The Rat Pack was one of the most prevalent bunch of singers and this game is a sort of homage or rat video slot version of their glory!!!

This 5 reel video slot is played over 30 pay lines, but interestingly it shows 4 horizontal view lines too, so not the traditional 3 horizontal lines. There are also 2 wild symbols and one of them the 2X will double your winnings.

There is a free spin feature which is activated with 3 or more SCATTER records and the fun part here is that the more you win, the longer you'll get to spin free spins.

The way this works is to do with the CYMBAL symbol! As long as this symbol keeps appearing, you keep spinning. The way the wins work is for each symbol that appears, you win the corresponding combo amount on the pay table structure. So for 3 symbols, you'll get 4x coin wins. In this special round 1 symbol pays out 1x bet win. There's one more feature to this, and that is each CYMBAL is held and nudged. So if you hit a symbol on a reel, the next spin will nudge it down one slot. This means more wins, more spins and potentially bigger wins!

Overall I really loved this game, I'm not a mathematician, so I don't know how having 4 lines across affects the win ratios, but it felt good and wins were coming more than often. I loved the clever free spin feature too, another good new feature invention by Microgaming.
