That's a lot to ask for a $42 worth of winnings. If it's asking for a $1270 wager/deposit, that's too much because if it happens to me I'd just leave it there.
The rule is clear that he should wager 30x of the winning amount from the free spins and the wager should be made from real deposit, so he needs to make a deposit (up to him how much) as long as he can wager the required amount with the deposit then he will be able to get the bonus.
He does not need to deposit $1270 but he should wager $1270 to convert the winning from the free spins into withdrawable balance.
Although I've experienced in some other casinos that asked me as well with these wagers and I did complied through the usage of my winnings without any other deposits. Because wagering and deposit requirements are two different requirements.
If it only asks for a wager, that's all you gotta do but if it's asking for both, it's not worth it if that's the case with too much amount. Maybe the owner/developer can adjust that to maybe 1x or 2x because that's usually the wagering requirements are.
Every casino has their own rules, some casinos let you to wager directly from the free spins winning but some other casinos ask you to deposit in order to wager and unlock the bonus.
Adjust the wager requirement to 1x or 2x? I believe if you own a casino, you will not have such a rule because you will need to spend a lot of money for promotions as it will be easier to be abused.
1x or 2x is normal wagering requirement for deposit without bonus, but normal wagering requirement for bonuses is 30-40x.
