Preselection Of Turns: A Verbal Randomness Generation System For A Board Game

Part 1: PRESELECTION OF TURNS
Before the game starts one player picks the turns in which they will have power. There are 12 turns in a game and a player may pick 6 turns. Whatever turns they don't pick are the turns when their opponent will have power.
Part 2: PLAYING : Players then begin the game. IF it is, ACCORDING TO THE PRESELECTION, a players turn to have power they get to decide how many squares their piece and their opponents piece move forwards BUT they must always choose a number between 0 and 7 (as in a dice roll).
Part 3: PENALTY and PRIZE squares: There are both penalty and prize squares on the board. Every time you move your piece onto a prize square, you win the number of points on that square and every time you move your opponents piece onto a penalty square, they lose the number of points on that square.
Part 4: WINNING - When one player reaches the finishing square the game is over. Whichever player has the most points at the end of the game is the winner.
WHY IS THIS RANDOM?: When a player is picking turns before the game they do not know in advance how the game is going to progress; what numbers are going to be picked by their opponent during their turns and which Penalty or Prize squares they will pick. In otherwords, when a player picks their turns before a game they are making a random selection.
