Unequal

Fill in the grid with numbers from 1 to the grid size, so that every number appears exactly once in each row and column. The clue signs between squares carry a further rule, and which rule depends on the game mode:

• Unequal mode: the clues are < signs, and all of them must represent true inequalities (i.e. the number at the pointed end is smaller than the number at the open end). Not every true inequality is shown, particularly at the harder difficulties.
• Adjacent mode: the clues are bars, and a bar means the two squares it separates hold consecutive numbers — one is exactly one higher than the other. Every bar the solution calls for is shown, so the absence of a bar between two squares tells you their numbers are definitely not consecutive.

Both modes are in the ‘Type’ menu, and ‘Custom type…’ has a Mode setting as well.

To place a number, click in a square to select it, then type the number on the keyboard. To erase a number, click to select a square and then press Backspace.

Right-click in a square and then type a number to add or remove the number as a pencil mark, indicating numbers that you think might go in that square.

Left-click on a clue to mark it as done (gray it out). To unmark a clue as done, left-click on it again.
