▦ Common Ground

Common Ground is a daily 3x3 sports puzzle built on real rosters from hoopR NBA data by sportsdataverse, nflverse and openfootball. In NBA and NFL, every square needs a player who played for both the row team and the column team. In soccer, rows are nations and columns are international tournaments, and every square needs a player from that nation's squad at that tournament.

1. Look at the team labeling each row and each column of the 3x3 grid.
2. Pick a square, then search for a player who played for both of its teams using autocomplete.
3. Pick a player to lock in your guess — each square gets one guess, nine in total.
4. Each player can only be used once across the whole grid, so plan your overlaps.
5. The grid finishes on its own once all nine squares have a guess.

Scoring

Each correct square is worth 11 points, and completing a perfect grid adds a 1-point bonus, for a maximum score of 100. Every square in the daily dataset has at least two valid real answers.

• Start with the square you are most confident about to lock in an early correct answer.
• Journeyman players who changed teams often are usually your best bet for tricky overlaps.
• Remember a used player cannot be reused — save your surest answer for its hardest square.
• If autocomplete returns no matches, the player likely never suited up for one of the two teams.

Are the players and teams in Common Ground real?

Yes. Every valid answer is drawn from real data in hoopR NBA data by sportsdataverse, nflverse and openfootball squad lists.

Is Common Ground affiliated with any league?

No. TrophyStreak is not affiliated with or endorsed by any sports league, team or players association.

Is there always more than one correct answer per square?

Yes, every square in the daily dataset has at least two valid real players who satisfy it.

Can I guess the same player twice?

No. Once you guess a player, right or wrong, they can't be used again anywhere else in the grid.

What happens if I run out of guesses?

The grid ends after nine total guesses, and unfilled squares simply score zero.
