Spring has sprung and it’s a beautiful thing. With the change of another season comes the release of a fresh batch of sweepstakes casino rankings. If you’re new to the Bonus Power Index (BPI) rankings system (welcome!), it’s our site’s proprietary rating system for sweepstakes casinos. We evaluate individual platforms on the basis of bonus totals, game totals, app store ratings, and popularity metrics.
If you’re a longtime fan (welcome back!), we have some strong newcomers in this month’s edition that are worth your time.
Without further ado, here’s the Bonus Power Index release for May 2026.

Easter Came Late: Lucky Bunny Makes a Splash
The most notable update to the BPI is the addition of Lucky Bunny casino. Launching in May 2026, Lucky Bunny awards new players with 5 Sweeps Coins upon signup. With just a 1x playthrough requirement, players can make good on the platform’s expansive game library to convert free bonuses to cash. Only Stake.us and Rolla finished the month with a higher Sweeps Coin bonus rating than Lucky Bunny.
In addition to $5 worth of free bonuses, Lucky Bunny is also our new Game Total champion, supplanting Sweep Las Vegas. Lucky Bunny’s library — 4,000 titles in total — marks a notable improvement from the previous high watermark of 3,100 and a significant step-up from the average game total of 798.18. Lucky Bunny’s catalog includes slots, table games, and crash games.
By finishing in the top 3 for Sweep Coin bonuses and number 1 for game total rating, Lucky Bunny is the most impressive addition to our ratings system since its inception.
Dorados Locos Tacos
Lucky Bunny’s launch comes alongside the release of another heavy hitter in Dorados casino. Despite the lack of an affiliation with Taco Bell, Dorados has been satisfying appetites for new sweepstakes casino players with its 2 Sweeps Coin/25,000 Gold Coin bonus.
In addition to its new user bonus, Dorados (like Lucky Bunny) has impressed with a strong game library that sits 2,800 titles strong. As of right now, only four platforms in our database offer more games than Dorados — Lucky Bunny, Sweep Las Vegas, Stake.us, and Sweeps Royal. Dorados differentiates from Lucky Bunny in that it does offer live-dealer games.
With a solid bonus and strong game library, the platform’s overall rating is primarily sullied by its low popularity metrics, suggesting it’s one of the most underrated operators on our list.
Stake.us Reamins on Top
For at least the fourth straight update cycle, Stake.us finishes the month as the top rated sweepstakes casino operator according to the BPI.
The combination of 25 Sweeps Coins on signup (5x playthrough), 3,000 games, and popular metrics that only Chumba can compete with give the platform some staying power. The only downside to Stake is its preference for crypto withdrawals. If you aren’t a crypto fan, other sweepstakes casinos like Rolla and WOW Vegas may make more sense.
