Official Rule Breakdown

According to the Boggle instructions (Hasbro), words must be formed by connecting adjacent letter cubes horizontally, vertically, or diagonally in any direction. A critical restriction is that a single letter cube cannot be used more than once within the same word. For example, if the word 'SILOS' is attempted and requires using the same 'S' cube twice, that word is considered incorrect.

Example Play Situation

Alice finds the word 'MOLAR' by connecting adjacent cubes. Bob tries to write 'SILOS', but realizes he would need to use the same 'S' cube twice, so he marks it as incorrect and looks for a different word instead.

Common Misconceptions
