This shows the screen when you start a problem. The bottom-right timer starts when you open the problem.
This is the solving mode so you can start right away.
Generally use the left mouse button. Using the keyboard with the mouse makes operation smoother.
Change the line width of the game grid here.
If you leave the check mark in the "Graying" button, islands (circles) will turn grey when they have the right number of bridges (the number in the circle).
Your settings for these buttons will be saved to preserve your playing environment.
On some computer systems the settings may not be saved.
You can enlarge and move the game board with these buttons.
Play using the mouse
In Hashiwokakero you only use the left mouse button when dragging (press left button and drag). This may seem strange at first but when you get used to it, it will feel quite comfortable.
You draw bridges by dragging the cursor from island to island.
When you drag along a bridge, a second bridge will appear there.
Draw several bridges at once by dragging between and across islands.
Delete bridges by clicking the left mouse button. A click deletes both one and two bridges.
When you want to start a puzzle again click the "Clear" button. The timer does not return to zero though. To reset the timer you have to close the problem and open it again.
The members page counts the number of times you open a puzzle.
When you want to redo a step, click the "Undo" button. By clicking this button repeatedly you can return to the start.
After solving a problem, click the "Check" button. If your solution is correct the screen will say "Congratulations." If your solution is not correct it will indicate one point that is not correct, click the "Continue" button to continue to solve this puzzle.
How to use Try-mode
When you want to draw a bridge temporarily thinking about the next step, use Try-mode. Click the "Try" button and the screen changes to Try-mode.
With the Try-mode, you can solve problems just like in the regular solving-mode. But the first bridge is brown, and the following are yellow.
Click the "Delete" button in Try-mode, if you want to delete your trial actions. All your temporary bridges will disappear and the point of your first action is indicated by a yellow blinking dot.
Click the "Fix" button in Try-mode if you want to set (make permanent) your trial actions. The color of all your temporary bridges are changed to black and you return to the solving-mode.
