WELCOME
This is a collection of 500 puzzles that will stimulate thinking and test your mental ability and problem solving abilities to the LIMIT.
The Books are arranged in ascending level of difficulty. The first chapter is easier than the other ones and so on. There are 20 levels of difficulty; each Chapter is clearly marked with its difficulty level.
To improve your mental powers it is advisable that you work methodically and resist the temptation to move at random from question to question. You may find the first couple of chapters easy. They are warm up charters only. More complex thinking awaits you later.
When you finish each chapter take time to look closely at the answers until you understand the logic behind them. You will find, as you progress the chapters, certain mathematical patterns re-occur or visual clues overlap.
THINK LATERALLY; DO NOT JUST LOOK AT THE OBVIOUS, LOOK AT THE PUZZLES FROM ALL ANGLES. THE REWARD CAN BE HOURS OF FUN.
GOOD THINKING AND GOOD LUCK!
