Scripts For Your Blog or Website

You can use the Puzzle and games Scripts free of charge for your own Website. This page explains how to do this.


Because of very low interest – almost no one but me uses the scripts – this page will not be updated anymore. If you are interested, please contact me via email.


You have two options: You can copy the scripts to your Website or Blog or you can use the scripts from www.janko.at

In either case you need two files or links to these files:

The first file is the same for all puzzles and games; the second file is specific to the puzzle or game; e.g.

Which puzzle/game specific file you need is documented in the list of puzzle and game scripts.

However, you must create a HTML file which looks like this:

 <script src="http://www.janko.at/Scripts/Puzzle.js" 
 <script src="http://www.janko.at/Scripts/Fillomino.js" 
<div id="data" style="display: none;">
unit 30

- - - - - - - - 2 -
- 1 - - - - - 4 1 -
- 6 - - - - - - - -
- 7 - - 4 6 - 1 2 -
- 1 4 - 7 6 - - 3 -

- 3 2 - - - - - 3 -
- 1 - - - - - - - -
- 6 4 - - 2 1 3 4 4
3 6 1 7 3 2 3 3 1 -
3 6 6 7 3 2 3 2 2 3
3 1 6 7 3 4 6 4 1 3
2 6 6 7 4 4 6 4 4 4
2 7 7 7 4 6 6 1 2 2
6 1 4 4 7 6 3 3 3 1
6 3 3 4 7 6 7 2 2 3
6 3 2 4 7 7 7 7 3 3
6 1 2 1 4 2 3 3 4 4
6 6 4 4 4 2 1 3 4 4
<script>new Fillomino().run("data");</script> 

The puzzle data are embedded within the HTML file but are not displayed thanks to display=none.

You can use any ID for the puzzle data (red). You can embed several puzzles in one page using different IDs. You must adapt the path specifications (blue) if you copy the files to your own website.

The format of the puzzle definition is similar for all scripts but differs in detail. A formal description of the puzzle data is t.b.d.

You can specify several puzzles at once:

<div id="data" style="display: none;">
<script>new Fillomino().run("data");</script> 

In this case some additional buttons are displayed to navigate between the puzzles (»previous puzzle«, »next puzzle« and »select puzzle by number«).

1) Sudoku includes several variants: Standard-Sudoku of any size with none, regular or irregular regions, diagonals, Kropki, Greater-Than, Odd-Even, Consecutive. There are several predefined layouts: Single, Gattai-2, Gattai-3, Samurai, Sumo, Flower, Butterfly. Other layouts can be customized.

Configuration of the Scripts

There are five areas for customization:

In general, configuration of a script may look like this:

<div id="data" style="display: none;">
 var p = new Fillomino();
 p.enable.solution = false;  

The blue line is an example for one of the many settings; in particular this setting disables the »show solution« function. For a description see the List of all configuration params.

If you need the same configuration many times, e.g. to translate all string to a language not supported from stock, you should provide the configuration in a separate script file:

 <script src="Customize.js" type="text/javascript"></script>
 <script src="http://www.janko.at/Scripts/Puzzle.js" type="text/javascript"></script>
 <script src="http://www.janko.at/Scripts/Fillomino.js" type="text/javascript"></script>
<div id="data" style="display: none;">
 var p = new Fillomino();

The script file Customize.js may look like this:

function customize (p)
  if (!p) return;
  p.enable.solution = false;
  p.uic.canvas = "#bbbbbb";
  p.uic.text = "#aaaa33";
  p.ius.author = "?втор";
  p.ius.source = "И?точник";
  p.ius.title = "?азвание";
  p.ius.size = "Размер";


The format of s function switch is:

var p = new(puzzle);
p.enable.function = true | false;

puzzle is the specific puzzle program (e.g. Fillomino, Akari); function is one of the values in the following tables:

Function Default Description
loadsave false the user can load and save a game state from/on the server (must be supported by the server)
undoredo true the user can undo/redo moves
zoom true the user can zoom the diagram
check true the user can check the current game state and mark all errors
solution true the user can display the solution
hint true the user can request a hint


The colors used by the script can be customized to meet the design of the Web page in which the puzzle/game is embedded. The format of a color specification is as follows:

var p = new(puzzle);
p.uic.color = "#rrggbb";

puzzle is the the name if the puzzle/game (e.g. Fillomino, Akari)

rr is the red value (00~FF),
gg is the green value (00~FF) and
is the blue value (00~FF).

color is one of the values specified in the following table:

Global Use
Color Standard Description
toolbarPanel #cccccc background of the toolbar
toolbarText #000000 text in the toolbar
messagePanel #cccccc background of the message line
messageText #000000 text of the message line
infoPanel #eeeeee background of the info line below the toolbar
infoText #000000 text of the info line below the toolbar

wall #000000 border of regions inside of the diagrams
grid #aaaaaa grid lines
text #000000 values entered by the user in white cells
text2 #ffffff values entered by the user in black cells
clue #3333ff given values in white cells
clue2 #ccccff given values in dark cells
cursor #ff0000 cursor frame
error #ff0000 error markers
smarkers #776655 symbol markers
vmarkers #660000 value markers
... ... ...
Specific Use
Color Standard Description
white #ffffff background of white cells
gray #dddddd background of gray cells
black #333333 background of black cells
cross #666666 crosses in cells
line #aaaaaa lines through cells

Note: The color #414243 must not be used!


Each script comes with built-in icons. If you want to provide your own icons you must specify these as follows:

var p = new(puzzle);
p.icons.id = "url";

url is the URL of the icon file or a data-URL, e.g.

p.icons.save = "save.gif";
p.icons.save = "http://domain/icons/save.png";
p.icons.save =  "data:image/png;base64,iVBORw0KGgoAAAANSUh...";

Data-URLs are preferable because of better performance (no additional http round trips).

id is one of the following id-values:

id Icon Description
prev previous puzzle
next next puzzle
reset reset puzzle
load load game state
save save game state
undoall undo all moves
undo undo one move
redo redo one move
redoall redo all moves
cmarker color markers
smarker symbol markers
vmarker value markers
hint show a hint
solution show the solution
check check solution
zoom zoom diagram
tilt tilt on/off
info info and feedback


The scripts contain user interface strings in English, German, French and Italian. The language actually used depends on the preferred content language defined in the browser used. If the preferred language is not supported English is used.

You may define the user interface strings for a language not supported from stock as follows:

var p = new(puzzle);
p.cc[n] = "cc";
p.id[n] = "string";

n is a number >= 10 (0~9 is reserved for languages supported from stock).

cc is the ISO Language Code of the language to be defined. For example, to define a Russian translation:

var p = new(puzzle);
var n = 10;
p.cc[n] = "ru";
p.author[n] = "?втор";

User interface strings in English, German, French and Italian:

There are more configuration params:

var p = new(puzzle);
p.config.id = "zeichenfolge";

id is one of the values from the following table:

id Standard Beschreibung
appid "oj-" Prefix for all CSS IDs used for script-created HTML elements. If a script is invoked more than once in a single HTML file each invocation must use a different CSS ID.
cookie "oj-" Prefix for the names of all cookies used by the scripts; e.g. to store the user's name or the user's mail address.
touch yes|no The script determines touch screens dynamically. For test purposes you may overwrite this value.
mobile yes|no The script determines mobile devices dynamically. For test purposes you may overwrite this value.

Server Support

All scripts can communicate with the Web server; i.e. send information to the server and read answers from the server. This must be supported by the Web server by custom scripts.

Features which need support by the Web servers are:

The server script should be prepared to handle (i.e. ignore) new features in future versions of the scripts.

Enabling the server support

To enable server support a script on the server must be provided by the Webmaster. The name of this script must be specified by config params:

id Standard Beschreibung
mailScript null Wird aufgerufen, wenn der Anwender im Info-Fenster auf "Absenden" klickt
timingScript null Wird aufgerufen, wenn ein Rätsel gelöst wurde und enthält vor allem Informationen zur Zeitmessung
loadsaveScript null Zuständig für das sichern und Wiederherstellen von Spielständen auf dem Server
solutionScript null Wird aufgerufen, wenn ein Anwender eine Lösung gefunden hat, die nicht mit der vordefinierten Lösung übereinstimmt (in den meisten Fällen ist dies eine unerwünschte Zweitlösung)
exceptionScript null Wird aufgerufen, wenn im Script ein Fehler aufgetreten ist (zwecks Diagnose)


var p = new(puzzle);
p.config.timingScript = "http://my.server.tld/timing.php";

Note that the pid (puzzle ID) param is optional. If specified, it can be used to identify the user and/or the puzzle in the server script. If pid is omitted, the puzzle can still be identified by examining the &ref param (see below).

URL params

Several URL params are provided by the applet when the server script is invoked:


Note that not all URL params are provided for all cmds.


&cmd= load | save | solution | timing | exception

specifies that the current event. Please keep in mind that future versions of the applets may support additional events.


is the number of rows of the puzzle


is the number of columns of the puzzle


is the puzzle ID as specified via the pid applet param. pid may encode a database key or a user name or even several items, e.g. "user,key"


is the URL of the page in which the applet is embedded.


is the time the user needed to solve the puzzle (in seconds)


is the time between the puzzle was loaded and the solution has been found (in seconds)


name of the solver if the solver enters his name in the "send solution" dialog.


score of the game; e.g. number of moves or number of points


is the error message for the exception


is the name of the method which caused the exception

Post body

The post body may contain huge text information which depends on cmd:

The response of the server must be:

Please note that the server must respond in any case, even if a cmd is not supported.


The timing script is invoked every time a puzzle has been solved successfully.

cmd timing
url params pid, r, c, utime, etime, ref
post body n/a
returns "ok" | error message

Two time values are provided to the timing script and it is up to the server script to evaluate one of them or both.

etime (elapsed time) is the time between the puzzle was loaded and the solution has been found. If a puzzle was loaded on Wed at 0:00 and the solution has been found on Thu 8:00 then etime = 115200 (=3600*32).

utime (used time) is the time the puzzler really needed to solve the puzzle. Let's explain this using an example:  The puzzle was loaded on Wed at 0:00 and the solution has been found on Thu at 8:00. On Wed 1:00 the game score was saved and on Thu 7:00 the game score was loaded again. Between 7:15 and 7.30 on Thu the user was in a phone call and did not work on the solution of the puzzle. In this case utime =  6300 (=115200 -108000-900; 115200 is the elapsed time, 108000 is the time between save and load and 900 is the time the user was in the phone call).

Any time period longer than 5 minutes without activity – no keyboard input, no mouse click, no mouse movement) is considered as inactivity and does not count as "used time". (This is how the phone call in the example above is identified.)

Save and Load

The Save script is invoked every time the user selects the "save to server" button; the Load script is invoked every time the user selects the "load from server" button.

cmd save load
url params pid, ref pid, ref
post body game score n/a
returns "ok" | error msg game state | error msg

pid and/or ref can be used to identify the puzzle and/or the user. The game score the server must send back for load must be identical to that one sent with save. The game score is a character string of variable length.


The solution script is invoked when a puzzle was solved by an user and the solution is not identical with the solution provided by the author.

cmd solution
url params pid, r, c, utime, etime, solver, score, ref
post body solution
returns "ok" | error msg


The exception script is invoked when an exception (i.e. an error, a crash) occurs.

cmd exception
url params pid, method, msg, ref
post body diagnosis information
returns "ok" | error msg

msg is a short description of the problem; method the the routine in which the exception occured; the post body provides additional information:

In most cases the exception is caused by a faulty puzzle definition.
