Aquarium Game
Level 1:five empty colored aquarium for 5 colored fishes.
Level 2: five empty colored aquariums for numbers 1–5.
Children choose a colored fish and place it in the matching aquarium.
When every aquarium is correct, a bubble-popping celebration appears.
After the children pop all the bubbles, Level 3 unlocks with numbers 6–10, using the same five colors.
That progression is much more like a real learning game: color matching first, counting practice, immediate feedback, then a playful transition to the harder level. I’m adding this full two-level structure now.
