Numberlink: How to play using Flash

Sample problemsRulesHow to play

Start window of Numberlink

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.


Change line width

Change the line width of the game grid here.


Paint setting

Put a check mark in the "Paint" button and the color of the cells you drag across will change to light blue.


Your settings for these buttons will be saved to preserve your playing environment.

On some computer systems the settings may not be saved.



Zoom function

You can enlarge and move the game board with these buttons.


Play using the mouse

In Numberlink 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.

Dragging mouse

You draw lines by dragging across cells (from cell to cell).

You can make draw turns without releasing the mouse button.


Deleting Line

When you drag on the lines already there the lines are deleted.


Confirm other number

When you put the mouse on a cell with a number, a mark will appear in the corner of the cell and also in the cell with the "other" number. This will help you to locate the other cell with this number.


Clear button

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.


Undo button

When you want to redo a step, click the "Undo" button. By clicking this button repeatedly you can return to the start.


Check button

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

Check button

When you want to draw a line 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. Your first action is indicated as brown and the following yellow.


Cancel trying button

Click the "Delete" button in Try-mode, if you want to delete your trial actions. All your trial actions disappear and the point of your first action is indicated by a yellow blinking dot.


Fix trying button

Click the "Fix" button in Try-mode if you want to set (make permanent) your trial actions. The color of all your trial actions are changed to black and you return to the solving-mode.
