š Limited-time offers that just dropped this week
Three of the newest sweepstakes casinos on the market recently dropped new sign-up bonuses.
The Ace Casino bonus code and Lucky Stake Casino bonus code both have identical offers. When you sign up, you will receive 7,500 Gold Coins (GC) and 2.5 Sweeps Coins (SC) instantly. You will also have the option to purchase 50,000 GC for just $9.99 (normally $24.99), and you will get 25 free SC with your purchase.
The Sixty6 Casino bonus code is even better. You get 50,000 GC when you sign up instead of just 7,500, but you only get 1 free SC compared to 2.5. I tend to prefer getting more SC, so the extra GC doesnāt necessarily make this a better deal, but the first-purchase offer is significantly better.
You will have to spend $19.99 instead of $9.99, but for that price, you will get 600,000 GC and a bonus of 60 free SC with your purchase. Thatās 12 times more GC for just twice the cost, plus more than double the SC you get from Ace or Lucky Stake.
š„ Trending platforms with exclusive bonus codes
MegaBonanza Casino is one of the hottest sweepstakes casinos right now, with a library of 1,200 online slots, several live dealer games, and some great promotions for both new and existing users.
With MassLiveās exclusive MegaBonanza bonus code, you will get 150% more coins on your first purchase, up to 600,000 GC and 303 free SC. Those amounts will cost you $299.99, but you can also get similar value at lower price points.
š± Best mobile apps for fast access and daily rewards
While you can play online casino games on both desktops and mobile devices, the latter is far more popular. You can play from anywhere and the gaming experience is just as good, if not better. Plus, logging in on your phone makes it way easier to remember to claim the daily rewards every day.
Crown Coins is one of my favorite sweepstakes sites for playing on a mobile app. The app is fast, the design is clean, and the library of 270+ online slots features some of the best game developers like Ruby Play and Booming Games.
The Crown Coins mobile app has a sterling 4.8/5 star rating on the Apple App Store. Unfortunately, itās not yet available on the Google Play Store, but you can get a comparable experience playing on the mobile browser if youāre an Android user.
When you sign up with MassLiveās Crown Coins bonus code, you will get one of the best sweepstakes no-deposit bonuses on the market: 100,000 Crown Coins (their version of GC) and 2 free SC. You will also get 200% extra bonus coins on your first purchase and a chance to spin a prize wheel with top prizes up to 2 million GC and 100 SC.
šø Editorās picks: Highest value deals right now
Spree Casino has the most valuable sweepstakes casino bonus for new users right now. Signing up with our Spree Casino bonus code will get you a whopping one million GC and 2.5 free SC instantly after creating your account.
The 2.5 free SC in that offer matches the best offers at other sweepstakes casinos, but the GC offer is where Spree stands out. You wonāt get close to one million GC on sign-up at any other sweeps sites.
I also like that Spree Casino throws in 30 free spins when you make your first purchase of $19.99. The GC and SC you get with that first-purchase offer are comparable in value to other sweeps promos for new users, but the spins add some extra value you wonāt get elsewhere.
š§ Expert insights on what makes these offers stand out
When I review the best sweepstakes casino bonuses, I look for two main things.
First, I focus on which offers have the best instant sign-up bonuses that you get without making a purchase. One of the reasons sweepstakes casinos have become so popular is that you can play games and even win cash prizes without spending money, so I value the no-purchase bonuses more than the first-purchase offers.
Second, I prioritize the offers with the most free SC. Check out our guide on sweeps coins vs. gold coins if you need a refresher on the difference. The short version is that only SC can be redeemed for cash prizes, so itās the more valuable currency.
All of the offers discussed above are among the best sweepstakes casino bonuses in terms of both the instant sign-up bonus and the free SC in their offers. As discussed above, Spree Casino and Sixty6 Casino in particular stand out for both of these reasons.
š Final thoughts on Septemberās must-claim bonuses
All of Septemberās must-have sweepstakes casino bonuses are worth claiming. While some offers are better than others, the quality of the offers is not the only reason to claim them.
Itās good to have a variety of options for playing online casino games, and different sweepstakes casinos offer different types of games. Some offer only slots, while others also offer table games and live dealer options.
No matter which sweepstakes casino bonuses you claim, you will enjoy hours of fun for a minimal cost, and you might even win some extra cash.
