The prizes are directly influenced by your turnover and rank level at wolf.bet, hard to say the exact values, to give you an example, we had a Delta player winning 0.015 BTC from 11 BTC wagered at wolf.bet 2 days ago. And he also won the race.
With house edge on wolfbet 1%, someone who wagered 11 btc is "expected" to lose 0.11 btc (1%*11 btc). If he won 0.015 btc from 11 btc wagered on VIP wheel, it's only 0.13% from his total wager amount ((0.015/11)*100%)
From that amount, that player still "lose" 0.11-0.015 = 0.095 btc from 11 btc wagered.
As a delta level VIP, the user received 20% rakeback of house edge. Beside that he also won the race. Probably first position and received 30% of total prize pool, which is more than 0.015 btc. So overall he got
- 0.015 btc from Daily VIP Wheel
- 0.022 btc from VIP rank rakeback
- 0.015+ btc from daily race prize pool
So the amount is 0.052+ btc, nearly 0.5% of his wager, half of the house edge. Don't you think it's enough? No casino will give back all the amount of house edge commission. Though this calculation is based on house edge. Maybe the user have made good profit or lost more amount in his game.
