The grid is divided into blocks of varying " "shape and size, with arithmetic clues written in them. Your aim is " "to fully populate the grid with digits such that: " "\n" "- Each row contains only one occurrence of each digit " "\n" "- Each column contains only one occurrence of each digit " "\n" "- The digits in each block can be combined to form the number " "stated in the clue, using the arithmetic operation given in the " "clue. That is: " "\n" "- An addition clue means that the sum of the digits in the " "block must be the given number. For example, `15+' means the " "contents of the block adds up to fifteen. " "\n" "- A multiplication clue (e.g. `60*'), similarly, means that " "the product of the digits in the block must be the given " "number. " "\n" "- A subtraction clue will always be written in a block of " "size two, and it means that one of the digits in the block " "is greater than the other by the given amount. For example, " "`2-' means that one of the digits in the block is 2 more " "than the other, or equivalently that one digit minus the " "other one is 2. The two digits could be either way round, " "though. " "\n" "- A division clue (e.g. `3/'), similarly, is always in a block " "of size two and means that one digit divided by the other is " "equal to the given amount. " "\n" "Note that a block may contain the same digit more than once " "(provided the identical ones are not in the same row and " "column). This rule is precisely the opposite of the rule in " "Solo's `Killer' mode (see chapter 11). " "\n" "This puzzle appears in the Times under the name `KenKen'. " "\n" "\n#30.1 Keen controls " "\n" "Keen shares much of its control system with Solo (and Unequal). " "\n" "To play Keen, simply click the mouse in any empty square and then " "type a digit on the keyboard to fill that square. If you make a " "mistake, click the mouse in the incorrect square and press Space to " "clear it again (or use the Undo feature). " "\n" "If you _right_-click in a square and then type a number, that " "number will be entered in the square as a `pencil mark'. You can " "have pencil marks for multiple numbers in the same square. Squares " "containing filled-in numbers cannot also contain pencil marks. " "\n" "The game pays no attention to pencil marks, so exactly what you " "use them for is up to you: you can use them as reminders that a " "particular square needs to be re-examined once you know more about " "a particular number, or you can use them as lists of the possible " "numbers in a given square, or anything else you feel like. " "\n" "To erase a single pencil mark, right-click in the square and type " "the same number again. " "\n" "All pencil marks in a square are erased when you left-click and type " "a number, or when you left-click and press space. Right-clicking and " "pressing space will also erase pencil marks. " "\n" "As for Solo, the cursor keys can be used in conjunction with the " "digit keys to set numbers or pencil marks. Use the cursor keys to " "move a highlight around the grid, and type a digit to enter it in " "the highlighted square. Pressing return toggles the highlight into a " "mode in which you can enter or remove pencil marks. " "\n" "Pressing M will fill in a full set of pencil marks in every square " "that does not have a main digit in it. " "\n" "(All the actions described in section 2.1 are also available.) " "\n" "\n#30.2 Keen parameters " "\n" "These parameters are available from the `Custom...' option on the " "`Type' menu. " "\n" "_Grid size_ " "\n" "Specifies the size of the grid. Lower limit is 3; upper limit is " "9 (because the user interface would become more difficult with " "`digits' bigger than 9!). " "\n" "_Difficulty_ " "\n" "Controls the difficulty of the generated puzzle. At Unreasonable " "level, some backtracking will be required, but the solution " "should still be unique. The remaining levels require " "increasingly complex reasoning to avoid having to backtrack. " "\n" "_Multiplication only_ " "\n" "If this is enabled, all boxes will be multiplication boxes. With " "this rule, the puzzle is known as `Inshi No Heya'. " "\n" ; const char quick_help_text[] = "Complete the latin square in accordance with the arithmetic clues.";
