The terms state that winnings from Mega Money Wheel Free Spins are credited as bonus funds. The bonus balance cannot be withdrawn directly: on both the first and second bonus steps, 200× wagering is stated before transfer to the cash balance. For a 100 USD bonus the terms illustrate roughly 20,000 USD in slot bets that count at 100%. This is a volume of bets, not a requirement to deposit another 20,000 USD at once.
Game contribution and Mega Money Wheel main prize
Blackjack, roulette, other table games and live casino count at only 2% under the same terms. The terms also name games that do not count at all. Bonus value therefore cannot be assessed by size alone: it also depends on which games the player wants to play.
For the main jackpot prize from Mega Money Wheel, the terms describe a special option to ask customer support to transfer winnings from bonus to cash balance. This explicitly applies only to the main prize, not to any Free Spin win. The terms also warn that playing with these funds before contacting support may affect how they are treated.
