If you’re not in a state with legal sports betting, there are numerous “DFS pick’em” products already well-established or popping up around the market. In these games, you’ll select players to go above or below pre-set player statistics, tie them together, and increase your payout the more entries you add.

Three of these sites are each offering $100 promos this weekend:

We’ll dive more into these offers and products below.

So how do these contests work, anyway? Just pick player statistics — higher or lower than the listed amount by Underdog — and if they all win, you win.

So in this example from the Underdog homepage, I took Nikola Jokic higher than 15.5 points, Lionel Messi lower than 0.5 goals, and Joe Burrow higher than 1.5 touchdowns. If it wins, I’ll 5x my $10 entry for $50 total plus my $10 back.

Underdog offers fantasy football products in most states, but it’s pick’em is available in slightly fewer. Pick’em is in IL, IN, KS, NY, VA, WY, DC, AL, AK, AR, CA, FL, GA, ME, MN, MS, NE, NM, NC, ND, OK, OR, RI, SC, SD, TX, UT, VT and WI.

Boom offers similar products to Underdog, with a few key differentiators — you can play “longshot” categories to 40x your payout or “favorites” categories to 3x your payouts.

Boom Fantasy operates in IL, KS, MI, WY, DC, MA, AK, AR, CA, FL, GA, KY, MN, NE, NH, NM, NC, ND, OK, OR, RI, SC, SD, TX, UT, and WI.

You may know, or even play on, Sleeper for season-long fantasy football. But they’ve also been running a product called Sleeper Picks, which functions similarly to Underdog and Boom (and even the ultra-popular PrizePicks).

One of the big standout features on Sleeper is the ability to create entries with your friends in real-time so you can play the same entries together with ease.

Sleeper Picks is available in AK, AR, CA, CO, FL, GA, KS, KY, MA, MN, NE, NM, NC, ND, OK, OR, RI, SC, SD, TX, UT, VT, WI, WY and Washington D.C.
