Free Bets

What is the most effective way to use a free bet? NJ sportsbooks like Draftkings hand them out like candy. Since you dont get the risked amount back, i think it makes sense to only make bets better than even odds. Do you just go for longshots? What's the math here?

I always use them for futures

Pertaining to FanDuel's "free $500 wager," I know somebody that parlayed the whole $500 amount with 3 decently favored favorites. All 3 favorites were no more than -200 and it paid out around $1200. But with those promotions, you should bet it on:

-A decent long shot, probably upwards of +300 but no higher than that.

-As stated above, futures but I don't know the rules for that

-A parlay

BOL to you and I'm looking forward to my free bet too since I live in PA.. 

Not only that free $500 when you sign up Square but some of them like DraftKings and FanDuel have promotions where you can qualify for free bets and its quite easy to achieve..in the $50 and $100 range..thats why I throw most of mine on futures for decent +300> odds on things. 

It happens that at registration they give free bets or money for the first bets.

I heard that too, but I never used it that way.
