    The game necessitates screen time, which might be a concern for parents who prefer to limit their children’s exposure to electronic devices.
  • Limited Age Range
    Osmo Numbers is primarily designed for younger children, which may limit its usefulness for older kids or those already advanced in math.
  • Potential Cost Barrier
    The cost of the Osmo system and the Numbers game might be prohibitive for some families, especially if they need to purchase a compatible device and Osmo base separately.
  • Storage and Maintenance
    The physical tiles and base require storage space and can be easily misplaced or damaged, which adds a maintenance aspect for parents.
