Gene Network Game is an educational puzzle game. Players aim to create proper gene networks from given promoters and genes. Through this game, the player can learn basic knowledge of gene networks and can be helpful when trying to understand other team's constructs and eventually to create their own construct. This game is also usable as a tutorial for modeling & simulation.
At the beginning of the stage, the player has some promoters and genes in his inventory. Using this inventory, he/she aims at creating a network capable of reaching a certain output protein concentration (Left).

A stage is completed when the player aligns genes in the correct order and the outputs level is achieved (Right).
The game is also implemented with a stage editor. In the editor, you can assign promoters and genes, adjust parameters (copy rate, degradiation rate etc.) and create your own stage. The editor is designed so that you not only to enjoy your own stage but it can also be used as a simple modeling tool which enables you to obtain preliminary knowledge about conducting modeling and creating simulations. It will be a first step towards using more technical modelig software such as Matlab.

If you open a textbook on systems biology to learn the dynamics, students may find themselves put off by the mathematical knowledge required or the volume of the text, often unnecessary for a simple iGEM project.
So it would be helpful if there is a tutorial from which beginners can learn sufficient information about gene network dynamics for an iGEM project.

We implemented an in-game tutorial for the Gene Network Game.
During the Asia jamboree, we demonstrated our software to participants from other teams, and we noticed:
the meanings of symbols on constructs are not commonly known,
some of participants were not familiar with the dynamics of protein concentration.
So we made guides to provide background knowledge and made it
easier to use for beginners.
Additionaly, we documented some instructions in the in-game tutorial
in addition to the tutorial videos. You can get the PDF version of the tutorial here.
We improved the stage editor.
The GUI is refined. Now you can see the graph of regulation relationships.
Also we documented instructions for the editor, the principles and backgrounds of the model in the in-game tutorial described above.

Through this game, the player can learn basic knowledge of gene networks and can be helpful when trying to understand other team's constructs and eventually to create their own construct. This game is also usable as a tutorial for modeling & simulation.

A stage is completed when the player aligns genes in the correct order and the outputs level is achieved (Right).
Completing successive stages, the player will learn ideas from "What are promoters and genes?" to "Genetic oscillators and toggle switches".
The game is also implemented with a stage editor. In the editor, you can assign promoters and genes, adjust parameters (copy rate, degradiation rate etc.) and create your own stage. The editor is designed so that you not only to enjoy your own stage but it can also be used as a simple modeling tool which enables you to obtain preliminary knowledge about conducting modeling and creating simulations. It will be a first step towards using more technical modelig software such as Matlab.
Background
Planning Biobrick construction is perhaps the most important iGEM activities.
To do this, participants have to be able to understand constructs designed by other teams and go on to design their own.
This includes knowledge on what will happen when a specific BioBrick promoter is connected to a gene,
and further when such complex parts are combined.
In addition, in order to reach a full understanding of how a developed construct may behave,
we believe it is important for one to be able to create an image of how protein concentrations may evolve in time.
We have found that this is often especially difficult for students getting started with iGEM,
at which time many seem to have a fuzzy image of how protein production could be 'on' or 'off.'
As the project proceeds, students may need to assess the feasibility of the constructs they intend to create (for have already created).
Many teams do not get around to doing this or in some cases attempt this at a stage when construction has already ended and it is too late to turn back.
If you open a textbook on systems biology to learn the dynamics, students may find themselves put off by the mathematical knowledge required or the volume of the text, often unnecessary for a simple iGEM project.
