Excel/VBA - the Boggle game

The rules of the game

As explained on Wikipedia...https://enikipediarg/wiki/Boggle:

"The game begins by shaking a covered tray of sixteen cubic dice, each with a different letter printed on each of its sides. The dice settle into a 4x4 tray so that only the top letter of each cube is visible. After they have settled into the grid, a three-minute sand timer is started and all players simultaneously begin the main phase of play.

Each player searches for words that can be constructed from the letters of sequentially adjacent cubes, where "adjacent" cubes are those horizontally, vertically or diagonally neighboring. Words must be at least three letters long, may include singular and plural (or other derived forms) separately, but may not use the same letter cube more than once per word. Each player records all the words he or she finds by writing on a private sheet of paper. After three minutes have elapsed, all players must immediately stop writing and the game enters the scoring phase."


In the Boggle.xls workbook, you need a grid to accommodate 16 letters. To do this, we will appoint a range of 4X4 cells, in the D2:G5 example:

Insert a defined name:

Menu: Insertion

Choice: Nom

Click: Définir

Names in workbook => type: grille

Refers to => enter: Feuil1!$D$2:$G$5

Click on Add.
