With football back in full swing and online gambling riding high, free spin casino offers are being heavily advertised in September. Many deals have gaudy headline amounts, but the best-looking deals don't always provide the most value. Spin value and playthrough heavily impact a free spins bonus' worth. Let's discuss what defines a valuable offer, along with five deals worth claiming this month.
How free spins casino offers work and what each type gives you
Bonus spins are credited as a set number of turns on designated games at a fixed stake. For instance, a welcome promo might provide 250 spins worth $0.50 each ($125 in total value).
Three common types of free spins bonuses include:
Spins on sign-up or registration: This offer is typically part of a welcome package and credits you with bonus spins after completing registration. It's best when you're looking for a free bonus that can turn into real money, but it's also rare.
Spins on a qualifying first deposit: You receive this bonus after depositing enough to satisfy the required minimum deposit. For instance, you might have to deposit at least $5 to receive 500 free spins. This deal suits anybody who's brand new to a casino and wants to start with a large bonus,
Spins for existing players: An offer for players who've already made their first deposit and played through the welcome offer. These bonuses reward loyal players and can provide sustained value if they're frequent enough.
This free spins casino page covers more details on what to expect from various bonus types.
Free slots with bonus spins: The terms that decide the value
A large number of bonus spins doesn't automatically translate to a worthwhile offer. Spin value is important in this context because it defines the overall worth of a bonus. For example, 500 spins worth $0.40 apiece ($200 total) are just as good as 1,000 spins at $0.20 apiece.
Playthrough is also important because it determines the wagering needed to convert winnings into withdrawable cash. Some deals have no wagering requirement on free spins winnings, while others may require 1x playthrough or higher.
Expiration dates matter because they dictate how long you have to use bonus spins before they expire. Some operators give you a week or longer to use free spins, while others shorten the time to three days or less.
Most licensed U.S. online casinos deliver free spins in daily batches, rather than the entire bonus at once. Larger daily batches are preferable because they let you play free slots with bonus funds longer before waiting for the next day.
Game eligibility is another term impacting bonus value. More game variety means more freedom, whether you're looking for high RTP slots, less volatile games, bigger win potential, or something else.
Common games associated with free spins include 7's Fire Blitz Power Jackpot Royale Express, Cash Eruption, Huff N' Even More Puff Grand, and Sahara Riches Collect'Em MAX. Some games covered in our new online slots guide also appear regularly in bonus deals.
If there's one term to focus on above all, it's the value of each spin. All licensed U.S. casinos discussed here offer a $0.20 spin size, but watch for higher or lower values across the board.
Playthrough is the second most important term. You want the lowest wagering requirement possible to turn bonus spins winnings into cash.

DraftKings Casino
Bet $5, get 1,000 Flex Spins (incl. 100 Lighting Spins)
The DraftKings bonus lets you choose from 100+ slots when using the 900 Flex Spins and has a low deposit requirement. Additionally, some of the eligible slots appear in our real money online slots page's top-ranked slot games. The drawback is the 100 Lightning Link Spins can currently only be used on a few slots.
FanDuel Casino
FanDuel has increased its bonus from deposit $5, get 500 bonus spins to deposit $10, get 1,000 bonus spins. It runs a close second to DraftKings on most accounts, with the slight downside being a larger deposit requirement.
Fanatics Casino
Fanatics ties DraftKings and FanDuel for the largest offer, delivering 1,000 free spins when you deposit and wager $10. The main drawback is that every spin must be used on 7's Fire Blitz Power 5 Jackpot Royale Express.
Golden Nugget Casino
The Golden Nugget Bet $5, Get 500 Flex Spins bonus has the same specs as the DraftKings offer, including 1x playthrough and 100+ eligible games. The obvious downside is that you're getting 500 spins instead of 1,000.
Hard Rock Bet Casino
The addition of up to $1,000 lossback credits along with 500 free spins is a definite plus. However, the 500 spins are exclusively for Cash Eruption.
Which free spins casino should you pick first in September?
DraftKings is the best free spins casino this month. It stands out for its 1,000-spin package, huge list of eligible games, and $5 deposit requirement. The only reason I'd suggest looking elsewhere is if you're seeking extras, like FanDuel's $25 credit or Hard Rock Bet's lossback.
You must be 21+ and located in an eligible iGaming state (MI, NJ, PA, WV) to use any of these free spins bonuses. If you or anybody you know is struggling with gambling, seek assistance from the 1-800-GAMBLER national helpline.
Responsible Gambling
Bettors must be 21 years or older and otherwise eligible to register and place wagers at online casinos. If you or someone you know has a gambling problem, please seek assistance from trained professionals such as the Problem Gambling Help Network at 1-800-MY-RESET.
