❤️❤️❤️ You start with 3 lives.

1️⃣ Level 1: numbers 1–10 — master them all to level up.

2️⃣ Level 2: 11–99. 3️⃣ Level 3: 100–999.

⏱ Higher levels give you more time — not less!

🔁 Miss one in Level 1? It comes back until you get it right.

❌ Wrong answer or out of time = lose a life.

🎁 Every 8 correct earns a bonus life (max 5)!

🏁 Lose all lives → enter your name for the board.
