Objective / Rules - Each row and column requires exactly one A, B and C (and two blank squares). - The clues around the edge tell you which letter appears first in that row or column.
Help Read the help/walkthrough page on ABC View puzzles for a more detailed explanation and a walkthrough.
Keyboard Usage For pencil marks simply enter multiple letters per square. X is treated as a blank square. P = auto-pencil marks (updates A, B and C only). CTRL + arrows = move around the grid. SHIFT + 1 = highlight all squares containing A. SHIFT + 2 = highlight all squares containing B. SHIFT + 3 = highlight all squares containing C. SHIFT + 0 = clear highlighted squares.
Checking If you click 'Check' the system will check for incorrect squares. If 'Show mistakes when checking' is checked they will be marked in red. The system only checks squares that contain one large A, B C, or X, and ignores all others. If 'Highlight clues' is checked any clue where A, B or C appears first in the row/column will be highlighted - this does not mean that your answer is correct.
Uniqueness Each puzzle has exactly one solution, which can be found using logic alone and no guesses are ever required. If you think you've found another solution, then please double check the rules.
