Solution checking and revealing 

• Clicking on Check (icon at the bottom left corner) will check all letters and mark the incorrect ones only. It will not reveal any answers.
  Note: Subsequent reediting of cells marked as incorrect will have a black mark in the top right corner to remind you that it was checked earlier.
• Clicking on Reveal (icon at the bottom left corner) will reveal a single letter, a word or the complete solution. Use the selection box below the icon to specify whether you wish to reveal a letter, a word or the entire solution.
  Note: The command will mark the incorrect ones or unfilled squares with a red mark in the top right corner to remind you that it was revealed to be the correct answer.
• Sunday crossword solutions: The solutions for the current Sunday crossword puzzle are published a week after the crossword is published just as in the paper. In the interactive version, the solution will not be available for checking/revealing until the solution is published. You will however be able to work on the crossword. If you wish to check your answers later, use the Save button to save your work. When you resume your crossword page any day after the solution has been published, the check and reveal commands in the software will become enabled and will allow you to check your solution.
