Verdict
The clearest difference is in-app purchases: Cerulean at none against Memory Roulette's 3. Cerulean also leads on ratings volume (390 vs 1). Memory Roulette's advantage is update cadence (every 4 days vs every 2 months) and rating (5.0 vs 4.8). On price, ads, device support and iOS requirement there is nothing between them.
