I was already expecting my favourite game, Finn And The Swirly Spin, to play disastrously with just my deposit money, with no bonus money attached, because I have already experienced it several times before, and my play on this particular day certainly turned out to be that way yet again! I could only get 3 Keys with my $20 deposit, but after I got that $20 bonus money, the game played a lot better, and I could get to the 21 Keys level! See the great difference - from just 3 Keys to 21 Keys, on the same amount of money?! But to be fair to NetEnt, this oddity is also present with most other game provider games too - games tend to play a lot better when there's bonus money active!
The only thing that I like about this bonus offer is that the 50 free spins could be played in one go. Imagine if I had to play 10 free spins a day over 5 days! Sheesh! I would scream out in anguish! And as Starburst would usually go, any player would be damn lucky to get any decent win from this game with only 50 spins! It gave me a lousy $1+ win, which made my day even worse!
