Stack the Countries and Stack the States

Stack the Countries and Stack the States are educational geography game apps where kids answer questions to “stack” country or state shapes without toppling them. Players practice capitals, flags, landmarks, and locations while unlocking new maps and levels that make social studies feel like play. Created by Freecloud Design, the games are designed for elementary and middle grades and work well in short sessions. Parents like the clear focus on real geography facts and the one-time purchase model with no ads, making them a good-value alternative to many subscription apps.
