What GridClash is
GridClash is an independent sports trivia game. You claim squares on an Ultimate Tic-Tac-Toe board by naming players who fit both headings. These terms cover gridclash.app and its sport sites: hockey, basketball, baseball, football and City Connect.
Not affiliated
GridClash is not affiliated with, endorsed by or sponsored by any league, team, players' association or player.
Who owns what
Team names, logos, league and event marks, player names, images and likenesses belong to their respective owners. GridClash claims no ownership of them, and nothing on this site gives you any right to use them.

- Hockey statistics use NHL public data feeds. Hockey player photos load from NHL servers.
- Basketball statistics use BALLDONTLIE under a paid subscription (BALLDONTLIE terms). Basketball player photos load from NBA servers.
- Historical baseball statistics use the SABR Lahman Baseball Database under CC BY-SA 3.0. Player identity matching uses the Chadwick Baseball Bureau register under ODC-BY 1.0. The 2026 baseball data uses BALLDONTLIE under a paid subscription. Baseball player photos load from MLB servers.
- Football rosters, player statistics and game results are from nflverse-data, used under CC BY 4.0. Football player photos load from NFL servers.
GridClash is independent and is not affiliated with, endorsed by or sponsored by the leagues, teams or data providers named here. Naming a source does not claim rights beyond its applicable terms.
Versions and changes
- Lahman: the 1871–2025 release, imported November 5, 2026. GridClash keeps players who appeared in the majors from 1901 on (with their whole careers in the leagues MLB counts as major), counts teams that moved as the team they became, and works out season and career totals for its stat squares.
- Chadwick register: used only to match Lahman players to their official photo ids.
- nflverse-data: rosters from 1920 and weekly player statistics from 1999, refreshed nightly. GridClash counts teams that moved as the team they became, decides who played for a team by its own rules, and adds up season totals for its stat squares.
- Game results from the nflverse-data schedules release are used for Super Bowl winners from 1999 onward; the release identifies Lee Sharpe's nfldata as the upstream maintenance source.
- Super Bowl winners for the 1966 to 1998 seasons (Super Bowls I to XXXIII) are not from nflverse-data and are not covered by its license. GridClash keeps them as its own list, taken from the public record of Super Bowl results and checked against Wikipedia's List of Super Bowl champions, with each winner counted as the team it is today.
