✦ What's inside ✦

🏆

Daily Quests

Every morning, a new mission appears. Kids race to complete it before bedtime — and the satisfaction when they do? Priceless.

⚡

Challenges

Send a secret code to a sibling or friend. Same deck, same questions — who scores higher? It's friendly rivalry at its best.

🛡️

Grace Days

Life happens — a birthday, a sick day. Grace days protect the streak so kids don't lose everything they built. No stress.

👹

Boss Battles

Each week a powerful boss appears. Only the sharpest minds deal enough damage to defeat it. Victory means legendary rewards.

✨

Foil Cards

Rare, shimmering collectible cards drop when kids perform exceptionally well. They're beautiful — and kids obsess over completing the set.

⏳

Every day on Free = your child hits a wall.

Free plan = 1 deck/day. Premium = unlimited decks. That's 28+ extra learning sessions per month your child isn't getting.
