Logical games & quizzes

I’m keen on puzzling out quizzes and mathematical tasks, really. I’ve always loved maths and I like to test myself in various logical games. About two years ago I came across SUDOKU. You’ve probably heard about it. When I first saw it, I thought: Stupid. Why’s everybody so crazy about it?! But when I tried, I got involved very quickly

So if you want to test your skills then here u go!
