What size is the dMAT Latin Squares grid and how does the task work?

The dMAT Latin Squares task always uses a 5x5 grid, with some fields already filled in and one field marked with a question mark that you must solve for. The core rule is simple to state and demanding to apply under time pressure: each valid letter appears exactly once in every row and exactly once in every column.

Latin Squares Task Facts

The Method, Step by Step

• Scan the row containing the question mark and note which valid letters are already used in that row.
• Scan the column containing the question mark and note which valid letters are already used there too.
• Eliminate every letter that already appears in either the row or the column; the letter that survives both eliminations is your answer.
• If the answer is not yet obvious, fill in one or two neighbouring empty fields mentally first, since they often unlock the target field.

My Advice

Practice reading a 5x5 grid row by row and column by column until you can hold both scans in your head at once without losing track. Grid positions are labelled with Greek column letters and numbered rows, so also get comfortable with that alpha-to-epsilon labelling before test day.
