Yes i can confirm, i have won a minor prize twice now with 2 matching balls in the Free Lotto Draws using nothing but Free Tickets.
Saying that, I havnt withdrawn anything as i put my winnings into the Stake Pool so i cant comment on the withdrawal process from the site.
To explain my situation, the Stake Pool earns me more mBTC for every ticket purchased in the paid Lotto draws, which are drawn multiple times per day so multiple earnings/interest credited (usually two times per day). I personally have only contributed a small amount, equivalent to about $200AUD in BTC and am happy just watching my Stake balance grow so quickly (which means a lot of tickets are being sold). The Stake Pool is a risk however as the pool is used to partialy or fully fund a Jackpot win, so any Staked Coins are actually bets against the jackpot being won. Partial funds from ticket sales are distributed to Stakers (ratio by amount Staked by each Account) in the event the jackpot isnt won. You can remove your funds from the Stake whenever you like, it is processed imediately after the next draw due (as the jackpot is calculated using Staked Coins and advertised on their site so it wouldnt make sense if everybody ripped their coins out right before a draw the redeposited it after the draw).
I have come across a number of minor superficial bugs/broken Links/Dead ends on the site but these were all rectified and completely fixed within 24hours of notifying the site support. Something that actually shocked the crap out of me!
This team, honestly from my recent inquiries and communication with them, are willing to listen to us the punters and get the project right. I know my merit and contribution to BitcoinTalk is at most very minimal, im just not the type of person to post alot, i prefer to read quietly and take everybodies points onboard rather than posting mine. So yes i have no merit and nit av ot of history on these forums for anybody to trust what im saying however i have real money invested in 8Bet as staked coins and i have used the lotto both paid and free therefore i can give you my honest experience from that.
EDIT
i must make mention that i am in no way affiliated with 8Bet, i dont know the organisers personally or professionally only through support inquiries and bug reporting. I do not receive any form of renumeration from 8Bet or any affiliate associated with the site. my comments above are not paid forbor sponsored, they are my honest experiences and i am completely independent of 8Bet, its organisers and any affiliates.
in case anybody thought i was. im not.
