Odd Coin

Cách chơi

1. Tap coins to place them on the left or right pan, then press Weigh.
2. The balance shows which side is heavier, or if they balance.
3. Rounds 1–2: the odd coin is heavier. Round 3: it may be heavier or lighter.
4. After weighing, guess the odd coin (and heavier/lighter in round 3).

One coin is different. Use the two-pan balance across three rounds (8, 9, then 12 coins) to find it in as few weighings as you can.
