DIGITLE is a free game that is based on the popular Internet word game WORDLE. The difference is that it works with numbers.


For each puzzle, there are 6 AB Calculus problems, based on the topic. The first 5 have one-digit answers with repeats allowable. The 6th more difficult problem has a 5 digit answer with the possibility of leading zeros. So an answer of 496 would be interpreted as 00496.


Students have a choice. They can do the more difficult 6th problem first or do the easier 5 problems.


The correct answer to the puzzle is the 5 digits of the simpler problems, which have been scrambled. They will match the 5-digits answer whose digits are also scrambled to give the solution to the puzzle.


Like WORDLE, students place answers in the given blocks on the DIGITLE Application. The blocks will turn to colors based on:


Green:  the digit is in the answer and is in the correct spot.

Yellow: the digit is in the answer but is not in the correct spot.

Grey:    the digit is not in the answer.


For instance, in the picture above, the answers to the problems might be:


1) 2        2) 8       3) 2       4) 7        5) 1        6)   81227


To solve the puzzle. it took the student 4 tries until he got all the digits correct. then another guess before he had the correct answer of 27182.



For AB Calculus, we have 32 puzzles below.  Choose the topic you want and download it to get the puzzle problems.  Then go to the DIGITLE Application below to actually play the game.  Enter the Digitle Puzzle # and you're good to go!  You can play Digitle on a computer, a tablet, or your phone.


DIGITLE is a neat way to review important AB Calculus concepts and have some fun as well. It is intended that the game should take about 15 minutes if students know the material.


For teachers: After 6 guesses, the app tells the student the correct answer. There is a RESET button in case you wish to start fresh with another class. To use it, type in the 8-character password !FANUCCI.  But, like the real game of WORDLE, students only get one shot at a puzzle on the device they are using.  If they type in a puzzle number already played, they will see their previous results with no ability to reset.


Students also have the ability to share with friends via email their color-coded results without divulging the answer.  (Sorry, text messaging doesn't work quite yet).




If you are using this game for anything other than a fun way to challenge students, I suggest that you ask to see their work as proof that they themselves did the problems.


Once you choose your topic below, use the app to play the game.
