Hey Everyone, I was part of this community 10 years ago. I made a game that Steve Pavlina at Dexterity published and almost no one bought.
I'm a programmer, I like to build stuff and HATE to market and sell stuff. If you want to take my product and make a pile of money with it, I'll split it with you 50/50.
I owned picross dot com for several years before Nintendo took it from me. All I was left with was a few thousand user-made nonogram puzzles in my database. I've been trying to do something with them, but again, I'm not a business person.
So I've made a mobile friendly html5 page with a version of picross and it's pretty much complete, if you can monetize it I'd love to have your help.
But picross games on mobile suck right? Because there's too many little things to tap and too much zooming in and out! Not with my game. I automatically fill in every other cell in the puzzle, then highlight the unsolved cells one at a time and the user need only select "mark" or "blank". You still have to use picross-like logic, but it's faster and the UI is far simpler.
So this thing already exists, you can play it here http://www.questengine.com/quickcross/ I think it only responds to touch events so it may not work on a full desktop browser with mouse clicks. There's a google adsense ad that pops up after each puzzle, but please ignore it, I'm not trying to get clicks, I seriously want a person who's good at building business relationships and who's just looking for a product to work around.
Hope you'll have a look, thanks.
