Verdict
The clearest difference is price: AI Answer Roulette at Free against Brain Training Math & Logic's $0.99. AI Answer Roulette also leads on update cadence (fortnightly vs every 17 months). Brain Training Math & Logic's advantage is ads (none vs shown) and iOS requirement (11.0 vs 15.6). On in-app purchases and device support there is nothing between them.
