Build a Balanced Thali

Challenge: Tap 5 food cards to assemble a balanced Indian Thali. Speaker confirms: 'Roti, Dal, Sabzi, Curd, Salad — that's a PERFECT balanced meal!'

Why It Works & Notes

Instant audio categorization with color-coded LED feedback creates strong associative memory — green = healthy (go!), red = junk (slow!) — making nutritional awareness feel like a fun sorting game.
