Of course, but this also means that the chance of losing the free bet is much greater. Especially when you combine several "safe" games (like my multi-bet on the German Bundesliga this weekend, screenshot is in my previous post), the odds are attractive, but the probability is also very high that one of the games will "fall through" and you will lose the bet as a result.
No risk no rewards applies here, the ones who take risks get better rewards and the ones who don't take risks often get less in rewards. I know the chance of loosing will be more when we combine multiple bets but at the same time if we win the bet then there will be good amount in pure profit. The ones who're not risk takers will definitely go for a single but safe match but those who're risk takers might consider adding multiple matches on the bet slip.

Man, is it better to be a living dog than a dead lion? Because you are I know it well that a living dog is far better than a dead lion, even the carcass is worth less in the market when you try selling both...
And coming back to gambling, going with single bet and winning is still way better than going with multiple bet and end up losing, in the end, no body celebrates losers, only winners are celebrated, and no one is interested in knowing the level of risk you too and the level of risk the person who went for the single bet took as well, what people know is that you lost and he won, so he is better and luckier than you.
I am not saying it's not good to take risks, it good to take risks but only calculated risks, there are some risk people take and it will be a stupid risk, taking such risk won't get you any reward, you are just going to end up wasting your money and opportunities.
