Verdict

The call

The clearest difference is in-app purchases: RiddleGem at none against Brain Test's 12. RiddleGem also leads on ads (none vs shown) and update cadence (daily vs monthly). Brain Test's advantage is ratings volume (1.5M vs 1) and chart position (#1 vs unranked). On price there is nothing between them.
