❓ 玩法

1. Three short exercises in a row (about 2 minutes).
2. ① Number Rush: tap 1 to 25 in order, fast (focus).
3. ② Color Words: tap the ink colour, not the word, for 30 s (control). e.g. “RED” written in blue → tap BLUE.
4. ③ Flag Pairs: flip two cards at a time to find matching flags, in as few flips as possible (memory).
5. You get your brain age. Play daily to build a chart and a 🔥 streak.
