Daily word puzzle
Hashtag by The Planet Brief
Hashtag is a daily word puzzle from The Planet Brief. Four clues cross in a hashtag-shaped grid. Solve the words, protect your stars and find the hidden Hashtag.
How to play
Reveal one clue for free, type into the grid and use the crossing letters to solve the four words. The answers point to one hidden Hashtag.
How scoring works
You start with five stars. Extra clues, letter reveals and wrong Hashtag guesses cost stars. Solving a word after a paid clue earns half a star back.
When it updates
A new daily puzzle unlocks every day. Practice puzzles are available if you have already played today or want another round.
Hashtag is built as a quick daily puzzle rather than a long crossword. The grid is small, the clues are short and the hidden answer is the final test. A strong round means solving the clue words with as few reveals as possible, then using the crossing letters to make a confident Hashtag guess.
The score separates streaks from wins. Playing each day protects your daily streak, while completed puzzles count towards your win total. That means a missed answer does not erase the habit of turning up, but the leaderboard still rewards clean solves.
The daily board is shared, so everyone gets the same puzzle for that day. Your browser keeps local progress and streak information, while submitted scores are used for the public leaderboard and game analytics.
The puzzle is a lighter daily habit beside the publication's main work. The rest of The Planet Brief remains focused on source-backed climate and sustainability context, including the UK Climate Progress Tracker, the Carbon Market Intelligence dashboard and practical guides across carbon markets, environmental, social and governance reporting, net zero and green finance.
Hashtag is designed to be easy to enter and hard enough to feel earned: one small board, one hidden answer, one daily score.
