In such cases I always write a simple formula (or more if needed), apply the right filters and delete the unwanted rows.
For example, if you have a list of spins in column A, type the following into the B3 cell: =IF(OR(A3=A1,A3=A2,A2=A1),1,))
If you there is a repeat, it will show "1", otherwise FALSE. Filter down to 1's in column B and delete all rows.
