Implement some open-source bot for at least 2 platforms

It could be a simple game like Tic-Tac-Toe, Stone/paper/Scissors, or anything simple but covering as much different features as possible.

I'm ready to award $100 to a first good implementation (no promises though) if:

• it covers at least 3 platforms
• uses inline mode in Telegram
• has profiles linking between messengers
• can be hosted on Google AppEngine Standard
