Verdict
The clearest difference is ratings volume: Brain Games at 25K against Eureka's 510. Eureka's advantage is iOS requirement (12.0 vs 15.0). On price, rating, review sentiment and update cadence there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Brain Games sells 11 in-app purchases, starting at $3.99 per 7 days and Eureka sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.7 for Brain Games against 4.7 for Eureka. That said, the two scores are not equally well evidenced: Brain Games has 25K ratings behind it against 510, so its average is the more settled of the two. Written reviews are what separate them: 84% of Brain Games's written reviews are positive against 77% of Eureka's.
Brain Games ships an update fortnightly, Eureka every 4 weeks. The most recent releases landed on September 25, 2026 and September 19, 2026 respectively.
