What is cZeus?

cZeus is an original puzzle game that effectively exercises logic, mental arithmetic, and notably improves mathematical fluency and problem-solving skills.

cZeus is suitable for any age group, from school age to adults who like to keep mentally active.

cZeus is a grid-based puzzle game, with different difficulty classes and each grid has a unique solution. The grid can be drawn in many shapes and sizes, but is most commonly rectangular.

cZeus has four simple rules and the aim is to find the answers to a set of mystery numbers by using the given clues.

cZeus Puzzles

cZeus has six difficulty classes offering players diverse levels of difficulty ranging from super-easy puzzles that are good for regular numeracy practice, to super-challenging puzzles suited for experts.

The first 'Light Class' is an easy and intuitive way to learn the fundamental cZeus principles and can be revisited and replayed at any time. There are 14 levels within the Light Class and puzzles gradually get larger and more sophisticated. Plus, there are short tutorials at the beginning of each level that show the rules and how to play.

The next class, Mortal, is good for quick numeracy practice, and requires some logic and a basic understanding of cZeus rules. It is an entertaining alternative to traditional ways of refreshing times tables.

The need to apply logical thinking and a good understanding of cZeus rules really begins at Hero class and progressively gets harder. DemiGod is very challenging, while Olympian and Titan are mainly for wizards and serious puzzle players.

Unlike the other five classes, the Light class has no time limit to play, making it a great learning tool.
