From the first two dice, we see that 5 is adjacent to 1, 3, 4, and 2. Therefore, 5 must be opposite to 6. From the first and third dice, we see that 1 is adjacent to 2, 3, 5, and 4. Therefore, 1 is opposite to 6. This is a contradiction. Assuming standard die rules are not followed and based on the provided hint: faces adjacent to 2 are 1, 3, 4, 5. The only remaining face is 6. So 2 is opposite 6.
