Big 12 Championship Betting Promos & Offers: $5000+ in Bonuses for Arizona St-Iowa St

It took until the final Big 12 game of the season – between BYU and Houston – for the Championship Game participants to be decided and when the smoke cleared it was No. 12 Arizona State and No. 16 Iowa State left standing for Saturday's Big XII Championship Game. A spot in the College Football Playoffs will be up for grabs Saturday night and for bettors it's a great opportunity to claim one of the many deals and bonuses available from the Big 12 sportsbook promos available for this game. 

Arizona State (10-2) is enjoying a resurgence under second-year coach Kenny Dillingham in the Sun Devils' first year in the Big 12.

Iowa State (10-2) is in its second Big XII title game under veteran coach Matt Campbell, losing to Oklahoma in 2020.

Below we'll break all of the deals and bonuses from the top sports betting sites in the industry.

Best Big 12 Championship Betting Promos & Bonus Codes 

As long as you are at least 21 years old, a first-time customer at your preferred online sportsbook, and physically present in a state with legal sports betting, you can sign up for any of these Big 12 betting promos.

BetMGM Bonus Code ROTOSPORTS: One of the standards among deals for bettors has been the BetMGM bonus code ROTOSPORTS. The first-bet offer up to $1,500 remains one of the most consistent deals available on the market with some of the highest bet protection available.

If opening wager settles as a loss, BetMGM will provide you with a bonus-bet refund up to $1,500. A wager of $50 or more will see a return of five bonus bets — each worth 20% of your original wager, so you can go big. Bets less than $50 will yield one bonus bet matching your wager. 

This deal from BetMGM and all the Big 12 championship betting promos have a 1x playthrough, meaning a single win turns that bet credit into profits.

Caesars Sportsbook Promo Code ROTODYW: Bettors can turn small wagers into big profits with the Caesars Sportsbook promo code  ROTODYW because an opening wager at a minimum of $1 will lead to 10 100% profit boosts.

These boosts can be used on any wager you choose for $25 or less over two weeks. If you get on a hot streak you can take in a bankroll up to $2,500 thanks to these profit boosts. When you're thinking of the best Big 12 championship betting promos the Caesars Sportsbook promo code ROTODYW fits the bill.

Fanatics Sportsbook Promo: Bettors will have multiple chances to make a first impression when signing up with the Fanatics Sportsbook promo, which is offering a No Sweat Bet up to $100 each day for 10 straight days.

Your job is to find a bet – a wager on odds of -500 or better – and designate that wager to be your 'No Sweat Bet'. You can wager up to $100 on this and if the No Sweat Bet doesn't settle as a win, you will get a bonus bet matching the original wager amount up to $100. You can do this for 10 days.

DraftKings Promo Code: For bettors in DC, IA, KS, KY, LA (specific parishes), MD, MI, NJ, NV, TN, VA or VT, the  DraftKings promo code wants to give you $150 in bonus bets and all you have to do is win your first bet of at least $5. For all other participating states, DraftKings is going to give you those $150 in bonus bets once you make an opening wager of at least $5. And it's guaranteed win or lose.

Find a game with the best moneyline odds to ensure a win, and you'll get six $25 bonus bet credits either way. That's why DraftKings is among the best Big 12 championship betting promos.

FanDuel Promo Code: A $5 first-bet win when signing up with the FanDuel promo code will also deliver $150 in bonus bets to a bettor's account.

Winning a bet is never guaranteed, but FanDuel is willing to make it as easy as possible by stripping away the odds restrictions and letting you wager on any game in the library. Once you secure the win and receive the bonus bet credits, they can be broken into whatever denominations you like, giving you an opportunity to go as big or small as you want from one of the best Big 12 championship betting promos.

bet365 Bonus Code ROTOWIRE: Bettors can receive a First Bet Safety Net up to $1,000 when signing up with the bet365 bonus code ROTOWIRE.

Find your game of choice and make an opening wager up to $1,000 – don't be afraid to go big with that first bet.
