A while back, Sudoku was all the rage but I never tried it. I haven't got a mathematical brain in truth although one of the reasons is that there are so many other fun alternatives out there. There are many tests and quizzes on Softonic to test everything from your general knowledge to problem solving ability and powers of logic.

As an Englishman, one of my favourites is Pub Quiz Machine which is general knowledge based. It features questions on topics ranging from Film and Sport to Pot Luck. The format is very similar to Who Wants To Be A Millionaire but without the annoying host. If only it served pints of beer, it would be the perfect game. If you're looking for something a bit more sophisticated, then Trivia Machine features harder questions and a more simple, straightforward format. If you think your world knowledge is pretty impressive, then try World of Where. It tests you on your knowledge of capital cities, flags and locations of countries worldwide.

On the other hand, if you want something that just flexes your brain muscles, then Brain Booster is a pretty tough workout. The game is based on word and numeric tests of logic that proceed through 8 levels of difficulty that will either leave you feeling like Einstein or tearing your hair out. Brain Workout covers a wider range of skills including Logic, Memory, Verbal, Numeric and Spacial awareness and despite the poor graphics and presentation, is one of the toughest tests you'll find.

Finally, if it's your knowledge of the Bible that you'd like to test, Scripture Challenge is one of the few options out there for Christians that will test your knowledge from both the Old and New testaments.
