Ask NH: What online game is suitable for contests?
I thought about all kinds of puzzle games like sudoku, people can be ranked by the time they use to solve, but the problem is it's easy to cheat with a sudoku solver program.
I thought about tetris, but the game is everywhere and too easy.
What I need is a culture-neutral game that's basically fun (kind of addictive), and can give every player a score, hard to cheat, and can be implemented in the browser preferably using Javascript. Any idea?
