FAQ
Answers to common questions about Phi.
How do I play Phi?
Swipe to move tiles on the board. When two adjacent Fibonacci numbers meet (like 1+1, 2+3, or 5+8), they merge into the next number in the sequence. Your goal is to reach the highest tile possible.
How does the Daily Challenge work?
Every day, all players get the same starting board. You have one attempt to get the highest score. Results appear on the global leaderboard via Game Center.
Why can't I see leaderboards?
Leaderboards require Game Center to be enabled. Go to Settings > Game Center on your device and make sure it's turned on and you're signed in.
Is Phi free?
Phi is free to download and play. You can remove ads with a one-time purchase that supports Family Sharing — buy once and share with your whole family.
How do I restore my purchase?
If you've previously purchased ad removal, it will restore automatically when you sign in with the same Apple ID. If it doesn't, go to Settings within the app and tap "Restore Purchases."
