Two things are missing as far as I can see.

There is no CREATE-statement for the Sudoko table. But since the schema for the table is shown, it is trivial to put this in:

IF EXISTS (SELECT * FROM sys.tables WHERE Name='Sudoko')

DROP TABLE Sudoko

CREATE TABLE Sudoko (

RowId TinyINT NOT NULL,

ColumnID TinyINT NOT NULL,

CellValue TinyINT NULL,

CONSTRAINT pk_sudoko PRIMARY KEY (RowID, ColumnID)

)

A more serious problem occurs at the end of the final implementation of SolveSingleCells - where the sp calls the procedure RemoveSolvedCells. This procedure is not defined anywhere in the article.
