I agree with you on Centre Court. I play that game all the time ever since its release, and 200 spins without a feauture used to be exceptional.
My last session at GoWild I went over 1200 spins, no feauture.
Not in one go, did 300 spins, changed games, won some on another game, did another 300, and so on.
The session before that one went the same, also about 700-800 spins, no tennisballs to be seen anywhere.
I used to say the game is low/medium variance, now its high variance.
Still tend to believe its a run of bad luck, the game has been very good to me in the first year, now its taking the money back..
BDBA has always been a bitch, I love that game, but don't chase anything on it, or it will eat you alive.
Just play 100-200 spins on it and hope you get lucky, if not, quit.
Got 4 valves yesterday for 20 free spins, got another 12 during free spins, 32 free spins total, paid 5x bet because of 2xJ + wild on the last spin.

But if it hits, its usually cashouttime!
