I didn't knew we had free spins on deposit as well. Just deposited some Satoshis today and was surprised to receive 10 free Wheel of Fortune spins.
It gave me a thrill to spin all 10 spins together so I chose that option but unfortunately I just received a few hundred spins and around 5k lottery tickets and just a few RP.
To be honest, I have never been lucky with those lottery tickets so considered it waste of efforts 
So over all I just received a few hundred sats and few RP from 10 free WoF spins
