I initially thought I'd won £47
I tried to withdraw £47 after winning it on my first £10 bingo bet but it remained pending and I realized that the T&C's hadn't been met, So I reversed the transaction and rather than the £47 returned to Bingo it returned to Sports.
So I transferred £40 from Sports back to Bingo using the 200% first deposit bonus.
It gave me a new total of £120 ( £40 real £80 bonus )
I had to turn it over 3x to qualify for the withdrawal so 3x£120 = £360
I won several times and once I'd spent £360 I still had £473
I still had £7 in my Sports account
I transferred the £473 I'd won in Bingo across to my Sports account which gave me a grand total of £480..!!! I then withdrawn the winnings to my bank and it's gone through..!!!
So you could possibly register, Claim your free £10, Transfer it over to sports, Then transfer it back and use the 200% first deposit bonus..!!!
Which would give you £40, Which you'd have to turn over 3x, So you'd have to spend a total of £120 on tickets. i,e You could win £200 on a house possibly more? So you'd have £80 after spending £120 on tickets. Ok so you might not win but you might not win anyway.
If it doesn't let you transfer the £10 to sports, Try withdrawing the free £10 and then cancel withdrawal as it will only remain pending anyway, It'll be transferred to sports and then transfer it back to Bingo using the 200% first deposit bonus reference code you get emailed to you when you claim your free £10.
I can't guarantee it'll let you do it because I'd won £47 after spending the £10 free money but I still hadn't turned it over 4x to qualify for withdrawal. It let me try to withdraw the £47 winnings though.
