The feature itself is pretty cool and I got 100x or more many times.
The graphics are pretty funny and I enjoy playing this game. The pays are pretty good and a good line hit on a big bet can make you serious cash. The symbols that pay big also mix and that makes it a bit easier to get a good win.
The other thing that happens to me if that the feature game gets stuck sometimes and after reloading the game the dog comes out on the first pick. These days if that happens I know that the dog is going to come out. It is like a glitch in the game and I think they should fix it.
Over all the game is average and I would not recommend it. If I remember correctly I only won big on this game once or twice and it was around €30 on €0.20 bet. My rating 5 out of 10.
