    minimum 3 max 6 (If you are splitting into 3 piles each time).

    incase you don't know: "!=" means "not equal"

    BEST CASE = 3 tries
    1)if A=B then the coin is in C. Split C into three piles (again A,B,C)
    2)if A=B then the coin is in C again. Split C into the three last coins.
    3)if A=B then C is the coin.

    WORST CASE = 6 tries
    1)A!=B (piles of 9)
    2)Now test A and C
    if A=C then split B into ABC
    if A!=C then split A into ABC
    3)A!=B (piles of 3)
    4)Now test A and C
    if A=C then split B into ABC
    if A!=C then split A into ABC
    5)A!=B (last 3 coins)
    6)Now test A and C
    if A=C then B is the coin
    if A!=C then A is the coin
