BOGGLE

 

                                  Boggle 
 is one of the most popular word search games. 
The rules are simple:

You have to find as many words as possible on the grid
You can move from one letter (dice) to another if it is a neighbor (in all directions)
You cannot use a letter (dice) more than once in a word

                                   Boggle  

is a word game in which players try to find as many words as they can from a grid of lettered dice, within a set time limit.
 It was invented by Allan Turoff and originally distributed by Parker Brothers. 
 The game is played using a plastic grid of lettered dice, in which players look for words in sequences of adjacent letters.

   A number of variations of Boggle exist, with some having more or less cubes; others feature an electronic timer; and yet others are designed for younger children, or are compact for travelling purposes.
  Due to the simple computer programming required, there are many electronic versions of Boggle, including servers that host the game online.
