A NOTE FOR GROWN-UPS

For parents

GaNannGenius is a free math puzzle arcade for kids and teens aged 8–17.

What we collect

Your child picks a nickname, a Neon Critter avatar and a 4-digit PIN. We never ask for a real name, email, phone number or photo.

What we store

Puzzle progress, stars, scores and avatar gear are saved with our database provider, Supabase (USA), so your child can continue on another device. Nicknames, avatars and scores appear on the leaderboards.

Chat is safe by design

Players can only send fixed, pre-approved puzzle phrases — no typing. Private chats need the other player to accept. Any message can be reported, and an adult reviews reports.

No ads, no purchases

Stars are earned by solving puzzles. Nothing can be bought.

Deleting an account

Ask the site owner and we'll delete your child's account and progress.

A FEW FRIENDLY NUDGES

How to solve puzzles here

1. Read it twice. Look at every number and picture before you start.
2. Look for a pattern. Many puzzles hide a shortcut — numbers that repeat, pair up, or cancel.
3. Try a smaller version. If it looks huge, try the same idea with small numbers first.
4. Use the hint steps. The first hint is free after a wrong try. Hints guide you; they don't give the answer away.
5. Wrong answers help. Every mistake shows you something. Try again — you can come back later for full points.
