Basic concepts


A session is a sequence of experiments or games in a lecture, meeting or presentation. Participants should not shut their browser during a session, as each participant receives an ID-number for a session. This allocation would be lost if participants close their browsers.

Tip: After the end of a session, you can use statistical tests to analyse whether there is a relationship between the different games of a session. For example, you can examine whether participants with higher mathematical abilities are more risk averse. For this purpose, participants' ID-numbers are stored in an Excel sheet.


Games consist of a sequence of stages. A game is typically characterised by a joint evaluation of the decisions and results at the end.

Tip: If you want to conduct a quiz consisting of several questions with unrelated results, it is advisable to create a separate game for each question.


Games consist of several stages. There are at least 2 stages, one for the decision input and one for the result output. Stages are ordered sequentially and are meant to be synchronization points in the game. Synchronization means that for the next stage to begin, all elements of the previous stage must have been finalized.

Stages can be configured with several options. You can find more information here.

Assignment and Matching

You can define the basic settings of your game by choosing to assign participants to roles, treatments, groups etc. Further, you can choose how you want to rematch participants if you play several rounds.


Elements are the modules of each stage. A stage has two areas in which you can add modules: participants and lecturer.

You can chose from text elements, input elements (numerical input, likert scales, …), programme elements and output elements (histograms, bar charts, …). These can be combined and arranged as you like.

More information on Elements.

General Features in the Editing Mode

You will find several features at the top of the page in the editing mode which are displayed here.


These provide you with several options which are described below.

Tip: If you make any input in the editing mode and leave the input field the value is stored automatically.

Select game


Click on the button in the left corner to open the drop down list of your existing games. Clicking on a game will open the selected game.

If a game has already been played by at least 10 participants, it cannot be adapted any more. The same applies if the game was created by another person. You can, however, replicate the game and then adapt it.



By clicking on the button game a drop down menu opens.


Game settings: Clicking on game settings lets you change the name of the game and lets you specify whether you would like it to be public or not. By default, all games are public. This function is also available in the Overview on the Starting Screen. Also, you can provide additional information on your game. You can classify your game and provide information on the content and additional comments. This information can be accessed by other users and provides them with more details on your game.

Copy game: The currently selected game is copied and can then be edited and adapted.

Delete game: By pressing "delete game", the currently selected game is deleted. For your safety, you will be asked if you really want to delete the game. It is not possible to delete the game if it has already been started in the lecture mode. You then need to start a different game in the lecture mode before being able to delete the selected one. You cannot undo the deletion of a game.

New game: Creates a new game. A standard new game is always a single-choice question with four possible answers. Find an example of such a single-choice question here.


By clicking on this button, you can set different parameters of a game that can be changed easily in the lecture mode if you want to play the same game several times with different parameters.

Here is an example for a public goods game:



For some elements, you can enter the text in two different languages, English and German.


To switch the languages on and off, you can click on the flag Flags.PNG symbols above the elements.

For other elements, this function has not been implemented yet. In this case, you need to enter both languages in one text box, separated by $$, for more information see Text Box.

Error spotting

If you try out the game you just programmed and find that something doesn't work, you can use the new Diagnosis mode for error spotting. This shows you all variables during the game in the lecture mode.

Exemplified instructions for creating a new game

Here you can find step by step instructions for creating an Ultimatum Game including explanations of each step.
