Expert Pick: Best Casino Bonus for May

With one of the best sweepstakes welcome bonuses in the US, Crown Coins really stands out from the crowd. You can grab a 200% extra bonus up to 2.4 million coins, 114 SC, and 18 free spins with our exclusive first-purchase bonus. The no deposit bonus of 100,000 CC and 2 SC is smaller than Stake.us (250,000 GC and $25 Stake Cash), but the overall sign-up bonus remains generous!

Crown Coins also rewards its regular and most loyal players with one of the most impressive daily login bonuses at a sweepstakes casino. Log in for seven days in a row and receive 195k CC and 1.3 SC, a stronger value than McLuck’s 10,500 GC and 1.3 SC over the same time period. The VIP program also shines, with prizes from monthly bonuses and coinback to your own personal host.

The Big Pirate no deposit bonus gets you started with 20,000 GC, 2 Diamonds, and 2 Rum, with the Diamonds currency being similar to Sweeps Coins, and Rum being used to claim prizes in the Reward Market. While it’s a solid offer, it is a little on the smaller side compared to competitors like Crown Coins (100,000 GC and 2 free SC). However, the extra Rum on offer can go a long way to claiming free spins or Claw Machine credits.

With the first purchase bonus, you can add 250,000 GC, 25 Diamonds, 1 Rum Coin, and 1 Claw Machine credit to your account for just $9.99. This is one of the better sweepstakes casino bonuses for players on a smaller budget, though Big Pirate also offers packages up to $999.99 for bigger spenders.

Funrize gets new players started with a solid welcome bonus of up to 125,000 Tournament Coins (TC). The currency system differs from traditional sweepstakes casinos; however, they work similarly to Gold Coins and Sweeps Coins, with one currency available for free play and the other for prize redemptions. The no deposit bonus offer at Funrize exceeds many competitors, such as LoneStar and RealPrize (100,000 coins).

Don’t miss out on the regular promotions and bonuses at Funrize, with one of our favorites being the Adventure Map, allowing you to roll the dice and proceed across the map with a chance to land on hidden prizes. You can also pick up a daily wheel spin, exclusive Funrize tournaments, and even scratchcard tickets.

Stake is one of the most well-known names in the casino world, and its sweepstakes site is no different. The no deposit bonus of 250,000 GC and $25 in Stake Cash is one of the most valuable we’ve seen, especially compared to Ace.com (Up to 57,500 GC + 27.5 SC). They provide new players with a great incentive to begin playing. Their three-part sign-up bonus also includes 3.5% rakeback across the house edge, a unique feature of Stake.us.

However, the bonuses may be inaccessible to players who aren’t familiar with cryptocurrencies, Stake.us’ only banking method. While redemptions are super fast (often within an hour), your bonus funds may be subject to transaction fees.

Regular players at McLuck are rewarded with some of the biggest bonuses around, especially the McJackpots tournament that can drop over 200 million GC at any time. In 2025, one fortunate McJackpots player bagged over 150,000 SC at once, one of the biggest sweepstakes casino prizes ever. We were also impressed by McLuck’s loyalty rewards, including bonus boosts and free SC supplies.

To improve in our rankings, McLuck needs to deliver greater value from its sign-up bonuses. While coin values vary by sweepstakes casino, many players won’t be enticed by its no deposit bonus of 7,500 GC and 2.5 SC, especially compared to Stake.us (250,000 GC and $25 Stake Cash).
