Do any Cluedo versions have different numbers of variables?
While all printed (the original patent had 10 characters) editions of the classic Cluedo have the standard 6-6-9 ratio, there have been a number of variants that include additional or changed options.

The first variant to include additional characters was the Clue VCR Mystery Game in 1985 with 4 additional options, then followed by Super Cluedo Challenge in 1986 with a 3 additional options of it's own.

The following is a potentially incomplete list of variants with non-standard ratios
(w = weapons, r = rooms, s = suspects, m = murdered):


Clue VCR Mystery Game : (1985) 10s:1+m:5w:5r
Super Cluedo Challenge : (1986) 9s:9w:9r
Clue Master Detective : (1988) 10s:8w:12r
Clue FX : (2003) 8s:6w:9r
Clue Discover the Secrets : (2008) 6s:9w:9r
