The ten-level path
Level 1 sorts one color into two groups. Then more colors, shapes, counting 1–5 and 1–10, memory with 4 then 6–8 pairs, big-to-small order, repeating patterns, and finally two rules at once.
Why sorting is real learning
Categories, one-to-one counting, and holding a rule in mind are preschool thinking skills. The game will keep the same short-level shell as phonics, with a graduate badge when it launches.
