Figuring out the most efficient way to use your free bets isn't easy. The restrictions employed by BetVictor and BetMGM do make it a bit simpler, though, as some of the bonuses have minimum odds.
There's a few different methods you can choose from, with two of them particularly popular.
The first is trying to roll your free bet into real money as easily as possible by putting your £10 free bet on a selection of around Evens (2.0). If it's a winner, you'll get a few quid back as real money that you can then withdraw or punt again at your leisure.
If you don't fancy that, then the other common way to use free bets is to simply punt it on a longshot. The odds of winning compared to the first method is much lower, of course, but the reward is much greater.
