GoWild - 50 free spins @ 1 coin @ 0.01$ = total worth 4.50$; winnings = 1.38$
Lucky247 - 10 free spins @ 1 coin @ 0.01$ = total worth 0.90$; winnings = 0.35$

Funny, the casinos where i deposited little or nothing lately gave me free spins and those where i deposited most gave me nothing
The slot can be bloody awful and boring to play with tons of hats passing the 5 reels and no WILD in sight, yet on the first spin after the hat disappeared - "bang" - there are wilds on 1 or 2 reels. Had once all 5 reels covered with hats (was not during free spins) and none paid, that is a solid 10 spins with not a single WILD to pay at least one of those hats.
Stacked wilds fell only on reel 4 & 5, had it about 15 times, none of the spins where it happened paid anything.
Cash hats pay most of the time 2 or 3 x bet
Free spins round, happy to make it to 20 or 30 x bet.
Line pays - very few and far apart, saw 1 x 4 in a row in over 1000 spins and it was of course 4 x 9's
BORING, BORING, BORING
One more thing about the free spins: Please, reps and casinos, give the free spins at a decent value, at least sometimes. I rather have 10 or 20 spins at 0.72$ instead of 50 at 0.09$. Don't get me wrong, i appreciate every freebie but lately there are lots of free spins given away and all of them are at minimum value
