Sweepstakes casinos run many of the same slots as real-money casinos, plus in-house exclusives. Knowing the studio tells you a lot about a game's style, volatility and transparency.

Studios release several RTP versions of many games, and each site chooses which one to run — so always check the figure in the game's information screen. Which titles appear also differs by site.
For clearing playthrough on a small balance, a lower-volatility game like Starburst gives a smoother ride; very high-volatility games like Wanted Dead or a Wild can turn a balance into a big win or zero in a few spins.
