My mind's been on developing some simple games in jQuery or in HTML5's canvas, but I haven't gotten there quite yet. I was wondering what sort of basic mini-games people might like (that already exist in some form on the web), like... Tetris, Snake, Asteroids... But I also want to learn how to hook them up with the currency system.
If I do get around to building actual mini-games that way, I'll gladly offer up at least one as example template for how the currency hook up works (which I haven't even begun to look into), and provide something simple enough that anyone can use it, and even optionally easily swap out the graphics for something that fits their site better.
There's a good, free, and very basic HTML5 Canvas game maker called
Tululoo, if you want to check it out. It's not the most advanced program, but it allows you to do quite a bit without any coding knowledge directly.
