inlay: white plastic
rules: in the very beginning, it came with a rules booklet showing the Schmidt logo according to the box cover (Gutes Spielzeug aus München) in black printing.
According to these rules, the attacker uses the black dice and the defender the green dice.
Later (and probably in most copies), they exchanged it to a rules booklet with blue printing. On the first page, the height of the lower case letters of the word RISIKO is not the half but nearly 90%!
According to these rules, the players decide the die color for attacker and defender. (So the dice could come in any 2 different colors).
There is a variant known for the first page of the rules booklet. The height of the last lower case letter "O" is like a capital (100%)! (The exact content of these rules is not known.)
