Mobile gaming has surged globally due to smartphone portability and fragmented play, yet health effects of flow through gaming remain underexplored.

In-game spending and higher education significantly boost flow experience, revealing education as a double-edged sword in digital contexts. These findings underscore complex relationship between socioeconomic factors and digital coping mechanisms
