Quick profile
Tell us your level, your courts in Lisbon & Almada, and when you play. Stored privately — never shared.
We find your fourth
Need a player? We match by level, location and time — and ask both sides before anyone's number is shared.
Play
You both say yes, you get connected, you're on court. Don't cancel — complete.
Built for the night your group is one short.
Lives in WhatsApp
No app to download, no account to create, no password to forget. If you can text, you can play.
Privacy-first
Your number is never shared without your yes. Both players confirm interest before any contact is exchanged.
Matched, not random
Every match weighs level, your courts, and when you actually play — so games are even and close to home.
Free for players
The Fourth Player is in alpha across Lisbon & Almada, in Portuguese and English, free to join while we grow.
Matched on what matters.
A good fourth isn't just any fourth. We line up the three things that make a game worth showing up for — and we never trade your privacy to do it.
Level
Beginner to advanced — we match levels so games stay even and everyone gets a real rally.
Location
Your courts across Lisbon & Almada, not a name on the other side of the river.
Timing
When you actually play — weeknights, early mornings, that regular Wednesday slot.
Court's up.
Who's in?
Send one message. We'll line up your fourth — verified, on your level, near your court. Then it's on you to win it.
