Establish the exact scope
Current pages report a low maximum cashout for welcome free-spin winnings despite a large overall package. That cap must remain separate from cash and deposit-bonus balances.
Capture the primary record
Record awarded spins, game, value per spin, expiry, resulting winnings, wagering multiplier, maximum bet, conversion event and stated cashout ceiling.
Compare like with like
Compare the account ledger before and after conversion and test how excess winnings are removed. Keep welcome spins separate from reload, cashback and VIP rewards.
Make the next decision
Value the spins from the capped withdrawable outcome rather than the advertised count. Save the balance history before requesting a payout.
