Verdict
The clearest difference is ads: Rank King App at none against Flash Roulette's shown. Rank King App also leads on update cadence (every 5 days vs every 5 months) and monetization model (free vs ad-supported). On price, review sentiment, in-app purchases and device support there is nothing between them.
