[Android Apps and Games] zerga:
What it is: Kicktrade is a free virtual multiplayer stock market, where you take on the role of an investor who buys and sells shares of the football teams currently participating in the Euro Cup event. Imagine the teams being like the companies on a real market and you compete against other players trying to make the most virtual money out of their development during the competition. Think of it like betting, but in a different way... although be aware that you neither pay or win any real money!

What's the idea behind it: The game is targeted to be casual with simple user interaction (you should be able to start playing immediately even without registering anywhere) but developing a high addiction factor, which can lead to micro management and wanting to understand the mechanics behind the system - but this is not required to play. The development of the prices should in the end reflect the expectations of the players in their teams and their real performance during the matches.

How the market works: The "companies" that you can trade start into the market with a price reflecting their FIFA ranking. You can take their development on the market or the matches into account to make a decision to buy and sell their stock. There is a bank that constantly buys and sells shares from and to you. The prices to buy and sell start above their current value to buy and below their current value to sell. However, those bank offers are adjusted in periods, so you will have to make a decision to buy or sell before someone else does - but also not too quickly because you then might waste money. Once a transaction has been made, the price of the company is adjusted to the transaction price (taking the trade volume into account) and the new buy and sell prices are calculated (and the cycle begins again).

Installation: I attached the game to this post (as the forum does not allow me to post any links yet). Since you are all privacy aware: You will have to accept 3 permissions to be able to play the game:

INTERNET : obviously to connect to the game server to fetch game data and send your actions.

WRITE_EXTERNAL_STORAGE : to store cache data on your SD card. For example the icons of the teams in the market. All data can be wiped in the preference menu.

READ_PHONE_STATE : to read the IMEI of your phone for authentication with the game server. No other information will be taken from your phone. This is required to prevent players from creating multiple accounts.

The development: This project has been implemented by one person alone (me) during free time as a learning project and is still in a testing phase. It is to my knowledge now bug free so I decided to enter the phase where more testers create more dynamics. This will allow me to tweak the game mechanics under more realistic circumstances. It is my first Android project, so any suggestions or comments are very welcome! (For example, if the required permissions prevent you from considering installing it and why)

The future of Kicktrade: The idea is to make more versions of the game to run during the longer running competition of several leagues in different countries. The Euro Cup is a perfect testing ground before release on leagues as it is a lot shorter with matches nearly every day. Until the end of the event I would like to have perfected the game mechanics and only afterwards I would like improve the UI and the code.

Keep up to date: You can follow the news on twitter @kicktradegame as well as on Facebook, or you can google for 'kicktrade' to find my blog called NeoZenCortexis among the first results. When there is a new version of the client available, you will see an update button on the main menu of the game. It is not always required to update but highly recommended (if you see an access denied message it could mean you should consider updating). At some point in the future, the game will also be uploaded to Google Play and get its own website but my free time is limited at the moment, so I will take it step by step.

How can you help: Most importantly, try the game yourself and/or invite your friends to play. I especially require feedback on the game mechanics at this stage of development and this requires a more dynamic market - although any other suggestion or comment is very appreciated as well. I have tested the game so far on Samsung Galaxy S, Galaxy S II, Google Nexus and a couple of HTC devices but none of them has hardware keyboards, so I expect some trouble there. Feel free to comment if you encounter any strange behavior with those. Also other than hi-res displays have not been tested.

Thanks: I would like thank all the people at XDA Developers and StackOverflow for the many hints I researched while learning how to work with android phones and ultimately even make my own app! Keep it up!!

I would be very happy if you help me test my game! For any questions or suggestions, contact me on twitter @kicktradegame, facebook or my blog (search for 'kicktrade'). Thank you very much in advance!!
