game looks nice, spins smooth n all, but cant say i got lucky. $50 in and only doubled a bit, bonus round popped once for a x5. kinda fun for short sessions tho, dont expect crazy wins.

played a few rounds of this, got a couple decent wins but mostly just small stuff. wilds helped a bit but didnt feel super consistent. would play again if im just killing time, not expecting huge payouts
