Havel Hakimi is an awesome puzzle game that is both fun and educational. During this game, you can learn about interesting things such as graphs and integers. You must read the rule and then try to solve the puzzle – you must reduce the numbers by connecting lines to other numbers.

Each time you connect a line, each number within the connecting circles will reduce. The aim is to have all circles showing number zero – this might sound easy but you must think logically! Can you complete every level? As you progress, you have to deal with more circles that have a higher number!
