A, is the answer to this question no?
I ask this question because if an answer is given, than A is the random god.
Inferring no answer is given, this means A is either the truth or lie god.
A, are you going to sing the answer to this question?
I ask this question because the answer is definite: if A sings da or ja, then da or ja is yes. If they do not sing da or ja, then the opposite of what they say is yes.
Inferring A says ja without singing, this means A is the liar, and ja means no.
So what we've got so far is that A is the liar, and either B or C is the truth, the other the random.
B, is the answer to this question no?
I ask this question because if an answer is given, than B is the random god.
If B says any answer, whether it's yes or no, B is the random god.
Else, B is the truth god.
Inferring B says da or ja, B is the random god.
Because A is the lying god, and B is the random god, C is the truth god.
