Comparing the best Kentucky Derby promos

We'll look at each promotion listed above through the following lenses: clarity, value, flexibility and payout speed, to give the best options for people trying to learn how to bet on the Kentucky Derby. 

Promo clarity

All the promotions are clearly defined when it comes to terms and conditions. TwinSpires and 1/ST BET are both transparent about how much is needed to be wagered in order to maximize the bonus funds.

Bonus value

The promotions at both TwinSpires and 1/ST BET give users a sliding scale for bonus funds, but with a lower return. If a user were to wager $800 under the TwinSpires promotion, they would get back $200 in bonus funds. Wagering $500 under the 1/ST BET promotion would also give a user $100 in bonus funds.

Flexibility

The TwinSpires and 1/ST BET promotions run for 30 and 60 days, respectively. Both promotions apply to races beyond the Kentucky Derby, so users don't necessarily have to wait until the Derby to sign up for an account to access each offer. 

Payout speed

TwinSpires will credit bonus funds to users as each $200 increment is passed, up to $400 within the 30-day period for the promotion. 1/ST BET will issue bonus funds to users as each $100 increment is passed, up to $500, within the 60-day period for the promotion. 1/ST BET will credit bonus funds within three days of each $100 increment being reached.

Responsible gaming

Racebooks are committed to promoting responsible gambling, and they provide essential tools and resources for anyone who may be struggling. If you or someone you know is experiencing issues with gambling, help is available.

In most states, the minimum age for betting on horse racing is 18, though some states require bettors to be 21 or older.

Support is available through trusted organizations like the National Council on Problem Gambling (NCPG) and Gamblers Anonymous. You can also call or text 1-800-GAMBLER (1-800-426-2537) anytime; assistance is available 24/7.

Summary

For users looking to place bets on the upcoming Kentucky Derby, both TwinSpires and 1/ST BET are currently offering bonuses to potentially increase your bankroll.
