Frequently Asked Questions

How do I play Krypto?

You're dealt 5 cards and a target number. Use addition, subtraction, multiplication, and division to combine all 5 cards and hit the target exactly. Tap two cards, pick an operation, and keep combining until one card remains — matching the target.

I'm stuck on a puzzle — is there a hint?

Yes. Tap the lightbulb icon at any time for a nudge toward a solution. Every puzzle dealt is guaranteed solvable.

How does multiplayer work?

Start a room from the multiplayer tab to get a shareable room code, or join a friend's room using their code. Both players race the same hand and target — first to solve it wins. You can request a rematch right from the result screen, and your win/loss score is tracked for the session.

Can I leave a multiplayer match?

Yes — tap the leave icon in the top right during an active match to exit the room at any time.
