On the App Store both sit at effectively the same score — 4.7 for Brain Games against 4.7 for Eureka.

Written reviews are what separate them: 84% of Brain Games's written reviews are positive against 77% of Eureka's.

UpkeepUpdate frequency

Brain Games ships an update fortnightly, Eureka every 4 weeks. The most recent releases landed on September 25, 2026 and September 19, 2026 respectively.
