Towers
|
||
|
|
<p>
|
||
|
|
Fill in the grid with towers whose heights range from 1 to the grid
|
||
|
|
size, so that every possible height appears exactly once in each row
|
||
|
|
and column, and so that each clue around the edge counts the number
|
||
|
|
of towers that are visible when looking into the grid from that
|
||
|
|
direction. (Taller towers hide shorter ones behind them. So the
|
||
|
|
sequence 2,1,4,3,5 would match a clue of 3 on the left, because the
|
||
|
|
1 is hidden behind the 2 and the 3 is hidden behind the 4. On the
|
||
|
|
right, it would match a clue of 1 because the 5 hides everything
|
||
|
|
else.)
|
||
|
|
<p>
|
||
|
|
To place a tower, click in a square to select it, then type the
|
||
|
|
desired height on the keyboard. To erase a tower, click to select a
|
||
|
|
square and then press Backspace.
|
||
|
|
<p>
|
||
|
|
Right-click in a square and then type a number to add or remove the
|
||
|
|
number as a pencil mark, indicating tower heights that you think
|
||
|
|
<em>might</em> go in that square.
|
||
|
|
<p>
|
||
|
|
Left-click on a clue to mark it as done (grey it out). To unmark a
|
||
|
|
clue as done, left-click on it again.
