Could you go over number 16?
My reasoning is that if S is not 6th, it must be 5th or 4th (three spaces for LM, O. If it's 5th, then R can't be 6th or 4th, so V is forced into 6th. If V is 4th, then R is forced into 6th, and V is forced into 5th. So B is correct: only two options.
Any tips on how I can get this faster? Overall the game went quickly but it took longer than around the 8 minutes I have.
