NBA Chainle, NFL Chainle, and Football Chainle are listed in the DLE Directory. They come from WordleCup. The directory’s other Chainle, at chainle.io, is a word puzzle with clue rounds. These three are roster puzzles.
NBA Chainle has the longest list of names

NBA Chainle posts one pair for the UTC date. You search for someone who shared a recorded game with the player currently on the board. When a new name has a verified link to the target, that last step fills in. Any verified route can finish. Hints, and picks the records cannot confirm, show on the score.
The searchable set is 112 players across 10 teams, built from 12 team-match records and 339 pairs. It is a curated slice of NBA history, so a real-life teammate can still be missing. Practice draws from the same list and keeps a separate save in the browser. The extra names are what make this board the widest of the three.
NFL Chainle offers more pairs than names

NFL Chainle uses the same chain. The board is smaller in people and larger in routes: 74 players, 9 teams, 11 team-match records, and 501 pairs. A receiver’s later stop, or a quarterback’s second team, is often the bridge. The pair still changes at 00:00 UTC, and the schedule repeats once those 501 pairs are used.
Fewer searchable players means you are scanning a shorter list. The longer pair schedule is what remains after the day’s route is done.
Football Chainle stays inside club dressing rooms

Football Chainle means soccer, the game played in the FIFA World Cup. Links are senior club appearances. An international cap does not connect two players here. The board is the smallest of the three: 57 players, 5 clubs, 6 team-match records, and 375 pairs. A transfer is the usual bridge between those clubs.
Because the graph is tight, a familiar move can finish a pair quickly. A player you only know from a national team will not help.
Which should I try first?
Start with NBA Chainle if you want the most names to sort through. Start with NFL Chainle if you want the most pairs waiting after today. Start with Football Chainle if you already think in club transfers and you want international matches left out.
Each one also has a practice mode, saved apart from the daily, when you want another pair before midnight UTC.
FAQ
Are these updated daily?
Yes. Each game gives everyone the same pair, and the next pair arrives at 00:00 UTC. NBA Chainle repeats after 339 pairs, NFL Chainle after 501, and Football Chainle after 375.
Do they require an account?
No. The daily opens without a sign-in. Daily and practice progress stay in the browser, so clearing site data or switching devices can drop a save.
What makes a link count?
Both players have to appear for the same team in the game’s recorded matches. Sharing a franchise name across different eras is not enough. On Football Chainle, national teams are outside the board.
Is this the same as the word game Chainle?
These WordleCup games connect athletes. Chainle on chainle.io is a separate daily word puzzle.
Conclusion
NBA Chainle, NFL Chainle, and Football Chainle share one habit: a dated pair, a teammate search, and a route that has to survive a recorded game. Pick the league whose rosters you can already picture. The next UTC day changes the pair. It does not change which sport you know.
