I just thought of another idea for Box 23. It could contain one of these 10 options:
Good Options:
QUADRUPLE
DOUBLE
+£20,000
+£10,000
+£5,000Bad Options:
MONEY BACKHALF
QUARTER
10%
NOTHINGDuring the usual Box 23 explanation, the player will choose 2 good options and 3 bad options at random for Box 23, using two bags of balls with the options hidden inside the balls.The adjudicator will then choose one of those five options at random to be Box 23's contents. The contestant will find about the five options for Box 23 immediately after the last box of the main game is opened.
This will solve virtually all of Box 23's flaws, and will make it possible (though EXTREMELY unlikely to the point that Channel 4 won't have to worry much about it) for Deal or No Deal to create a MILLIONAIRE.
