DailyCryptogram.com, WordPlays.com and BrainBashers.com offer free daily cryptograms online. A convenient feature of all three websites is that when a player enters a letter, the system fills in that letter on all spaces having the same clue letter.
DailyCryptogram.com displays the cryptogram in a large, bolded font on a high-contrast goldenrod background. A set of alphabet tiles just below the puzzle field helps remind players which letters are still available to choose; already-chosen letters fade into the dark gray background. Other features include an optional timer, a hint button and a button that shows the answer.
Players can solve WordPlays.com's cryptograms on the website or have the site email the cryptograms each day or on selected days. A category or theme displays for each puzzle, such as Fortunes or Literature. Players can also click a button for a hint.
BrainBashers.com does not offer hints, but players can restart their game, check their answers and give up to see the answers.
