Types of New User Offers Available

With so many great bonuses and offers available, it can be challenging to decide the best type. It depends on the bettor, though if you want to bet more and stake large sums, a deposit match may be best for you. If a gambler is just looking to have fun placing small wagers, bonus bet offers may be the way to go.

Deposit Match Bonuses

Deposit matches are when bettor deposits for the first time at their new sportsbook, and their deposit gets matched by the sportsbook. Match percentages can vary. Currently, DraftKings is offering a 20% match up to $1,000. This would mean a bettor would have to deposit $5,000 to get the full $1,000 match.

Be aware that while every sportsbook has multiple deposit options, some options may not be available for matching. Always read the terms and conditions before using a promo code or sportsbook promotion.

First Bet Offers

Bonus bet offers that are tied to a user's first bet are great in that the first bet typically does not have to be a large one. Right now FanDuel is offering a bet of $20 to get $200, regardless of whether your first bet is a winner.

First Bet Insurance

This might be the perfect offer for users wanting to make a big wager on their first bet. Basically, if your first bet loses, you can get refunded in bonus bets or bonus betting credits.

Live Betting on the NCAA Tournament/March Madness

For many bettors, one of the best ways to make lots of profit is with one of the most popular bet types. Live betting, or as some call it, in-game betting, is when games are being played, and users are wagering as the game is going on. Often, especially in the NCAA Tournament, favorites will get down early then the spread or moneyline is no longer in their favor. Now is a bettors chance to get a star-studded team like Gonzaga or the Kansas Jayhawks with plus odds.

Live betting will be available from the first four games to the sweet 16 all the way to the final four to the championship game for college basketball games. When you think a team is going to win but is down early, sometimes even just by a few points, that is the time to throw some money down.

There are a lot of bet types you can place live as well, they will vary by operator, but some include:

  • Parlays

  • Point Spread Bets

  • Moneyline Bets

  • Play Props

Regardless of what round it is, live betting moves quickly as oddsmakers all over the country are updating their list of games very quickly. Bettors have to make sure they are getting wagering done quickly, so they do not miss their bet on the team they want to get better odds on.
