How this data is usedHelp
Compare the completed rows and columns, then choose one of the six pieces for the empty space. Choose Check when you are ready. Your first checked answer is final. The rule is explained after you check.
Look at one feature at a time: direction, number of dots, or dot positions. At higher levels, more than one feature changes, or two pieces combine to make a third.
Tab moves through the choices. Arrow keys move between them. Space or Enter selects the focused choice. While a choice has focus, A–F or 1–6 selects a piece directly and moves to Check.
