Everyone loves playing at sweepstakes casinos for the exciting gameplay options and the abundance of sweepstakes promos. We are well and truly into March now, which means it’s the perfect time to explore the biggest sweepstakes promos for this month.
In this guide, I share some of the biggest sweepstakes promos of March 2025. With these massive promos, all users can claim a plethora of free Gold Coins (GC) and Sweepstakes Coins (SC) when they sign up for free. So, join me in finding the biggest sweepstakes promos at sites like RealPrize, Stake.us, and High5 Casino.
Before I can unpack the biggest sweepstakes promos at both new sweeps casinos and established sites, allow me to share a quick rundown of how these casinos operate. Unlike traditional online casinos, there is no real money gaming at sweepstakes casinos. Instead, you use virtual currencies at these casinos: Gold Coins and Sweepstakes Coins.
Below is a breakdown of how these coins work at the best sweepstakes casinos:
These coins are used for entertainment purposes only. You can get free GC through several sweepstakes promos, such as welcome bonuses and daily login offers. Additionally, if you prefer, you can also make optional GC purchases. Finally, please note that GC can never be used for prize redemptions.
These coins are considered more important at sweepstakes casinos since you use them for promotional play. While playing in sweepstakes mode, you can potentially redeem any of your SC winnings for real cash prizes, such as gift card vouchers and cash prizes. Remember, you must first comply with the SC redemption terms, such as playthrough requirements and redemption limits. You can get free SC with the biggest sweepstakes promos, such as welcome offers and daily login bonuses. Also, unlike with GC, you are prohibited from making any SC purchases at sweepstakes casinos.
There are several types of sweepstakes promotions that all users can claim at the top sweepstakes casinos. Below is a brief list of these offers:
These bonuses are given to all new users who sign up for the first time at sweepstakes casinos. Welcome bonus rewards include free Gold Coins and Sweepstakes Coins.
A popular sweepstakes promo for regular users is login bonuses, which reward players with free coins just for logging into their accounts.
Bring your friends to sweepstakes casinos, and when they sign up using your referral link/code, you will get some free Gold Coins and Sweepstakes Coins.
Depending on which sweepstakes casino you use, you will find a multitude of other sweepstakes promos, including free spins, GC purchase boosts, seasonal promos on major events and loyalty program rewards. These sweepstakes promos offer free goodies such as Gold Coins, Sweepstakes Coins and free spins.
I went deep into the sweepstakes scene to find the biggest sweepstakes promotions for March. My criteria were simple: I explored new sweeps casinos and established sites to find free Sweepstakes Coins and Gold Coins. Three of the biggest sweepstakes promotions with free SC for new users were from RealPrize, Stake.us and High5 Casino. Below, I review these sites and the current welcome bonuses for new users.
RealPrize is an excellent new sweeps casino launched in 2024 and welcomes new users with free SC. You can sign up using the banners on this page, and you will receive 100,000 Gold Coins + 2 Sweepstakes Coins. Additional free SC is available with the daily login bonus and other promos. Use your free coins to play hundreds of games like Gates of Olympus, Cash Pig and Blackjack Live.
A perfect all-rounder on the sweepstakes scene is Stake.us, which is renowned for big sweepstakes promos. As a treat for you, my friends, you can use our social casino promo code SPORTSGRID and claim a three-in-one welcome bundle with 55 Stake Cash + 260,000 Gold Coins + 5% Rakeback. With these free rewards and your SC, I recommend you play the Stake Originals titles like Stake Plinko, Stake Mines and Stake Dice.
Finally, there is High5 Casino, which has an array of big sweepstakes promos for March. To get started, click on any banners on this page to claim your exclusive welcome offer with 250 Gold Coins + 5 Sweepstakes Coins + 600 Diamonds. You can get additional free SC and GC with other sweepstakes promos such as the daily login bonus, loyalty program and friend referrals. I loved my time on the site, and with 1500+ games, you can try Sweet Bonanza 1000 and Wolf Gold.
I understand that while playing at sweepstakes casinos is free, the sites I mentioned above may not be available in some US states. So, if sites like RealPrize, Stake.us and High5 are unavailable in your state, two other excellent sweepstakes casino alternatives that you can use are MegaBonanza and Jackpota. These social casinos have many sweepstakes promos, including welcome bonuses and free daily login offers.
At MegaBonanza, new users can sign up and claim 7,500 Gold Coins and 2.5 free Sweeps Coins + a 150% first GC purchase option. While there are no free SC with this offer, you can get free SC with the other MegaBonanza promos, such as the daily login bonus, friend referrals, the optional GC purchase bundles and email promotions.
The other top sweepstakes casino alternative for the biggest sweepstakes promos is Jackpota. After signing up using the banner on this page, all newbies are welcomed with 7,500 Gold Coins + 2.5 Sweepstakes Coins. Thanks to several other Jackpota promotions, you can get even more free SC and GC when you claim the daily login bonus and seasonal promos like leaderboard tournaments.
It’s not too late to get in on the action and claim free Gold Coins and Sweepstakes Coins from the best sweepstakes casinos with the biggest sweepstakes promos this March. All the sites I have mentioned have a plethora of free rewards for users, and you can sign up at these sites with any banners on this page. Remember to play responsibly and have fun!
