Claim $50 in Free Play and $100 Match
This exclusive setup is designed specifically for new Fliff customers looking to get some skin in the game ahead of the Denver Broncos and Kansas City Chiefs matchup. I always tell my readers to maximize their starting capital, and this is exactly how you do it: create your account, spend just $5, and you are instantly rewarded with $50 in free play.
Better yet, Fliff is offering a 100% match on your first deposit up to $100, effectively doubling your initial bankroll. When we are chasing bigger payouts, having that extra cushion gives you the flexibility to build a winning strategy.
To claim this introductory offer, there are just a few basic rules of the road. This promotion is strictly reserved for new Fliff customers, meaning you cannot already have an existing account on the platform. Additionally, while Fliff is available in most states, you must be at least 18 years of age to play and physically present in a state where the platform operates legally.
Taking the Broncos or the Chiefs on Monday Night
When I am handicapping a game like this, I love looking at the straight-up moneyline to find real value. If you want to put your newly acquired Fliff promotional funds to work, this AFC West battle is a fantastic spot.
| Matchup | Favorite (ML) | Underdog (ML) |
|---|---|---|
| Denver Broncos at Kansas City Chiefs | Kansas City Chiefs (-129) | Denver Broncos (+110) |
Using your $5 in initial funds, you can back either side to win the game outright. If we lay the juice on the favored Kansas City Chiefs at -129 on the morning line, a $5 bet yields about $3.88 in profit, resulting in a total payout of $8.88 if they successfully defend their home turf.
On the flip side, grabbing the underdog Denver Broncos at +110 generates exactly $5.50 in pure profit. Should Denver steal the road victory, your total return is a solid $10.50.
How to Register Using the Fliff Promo Code
