For sports betting, FanDuel‘s Bet $5, Get $350 is the standout — the $350 in bonus bets is guaranteed (not win-dependent) for just $5 a day across a week, with a low entry and 7-day expiry on each drop. Hard Rock Bet’s Bet $5, Get $150 is simpler but smaller and only pays if your bet wins.

For the horses, AmWager‘s 100% match up to $50 (code AMWAGER) is the racing pick.

Best for a new customer in Colorado: FanDuel, for the guaranteed $350 value and the low $5 entry. AmWager is the add-on pick if you also bet the races.
