Hi @Spin2win!
It all depends on what games you like to play and how long you’d like your session to be. Don’t hold your bonuses to the end, like in bonus hunt style, you should never do this while you have bonus funds in play or they may confiscate your money.
To have the highest chance of wagering enough to clear the bonus funds, you want some low volatility action in the base game. Games like Bonanza and Diamond Mine are surprisingly good at this!
As a rule of thumb, you want a blanscr of at least 500x your stake. I’d recommend anywhere between 50p and £1.20 based on your balance.
Good luck.
