Daily Crossword scoring is calculated at the end of a game with this formula:
Player gets 10 points for every cell that was completed without help.
Bigger puzzles will have a higher total achievable score
If another player has a bigger or smaller score for the same date on the leaderboard, that means they played a puzzle for the different date (i.e., not today’s) – since there are 14 puzzles available to play every day and each will have a different total achievable score based on number of cells.
Completed without help is defined as:
Cell filled in correctly without using the Reveal function
If the player has Show Errors turned on in the puzzle’s menu, then completed without help means the cell has never shown a red, incorrect letter.
