Scruble Cube

Scruble Cube (Swedish and Finnish: Alfapet Twist) consists of a 4x4x4 Rubik's Cube, except a letter (along with the letter's point value) appears on each exposed side of each sub-cube. These letters are attached on circular pegs that freely rotate. This enables you to rotate each letter so that you can spell words in any direction.

Players have 90 seconds manipulate the cube to form a word in a straight line that may wrap around the cube. Other sub-cube faces have Scrabble-type point modifiers such as double letter score or tripe word score. You get to use these point modifiers if they appear at the beginning or end of your word. A variant allows you to use these modifiers to represent any letter. Players also score bonuses if their word covers more than one face and if it intersects a previously created word (and that word still appears on the cube).
