What is cZeus?

cZeus is an original puzzle game that offers innovative ways to practise numeracy and maths skills such as times tables, factorisation and algebra.
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

An easy 'Light Class' is introduced to guide the player through cZeus principles via some simple game plays. There are 14 levels within the Light class and the 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.

cZeus has five difficulty classes. You start as a Mortal, then progress through Hero, DemiGod, and Olympian to the most difficult class, Titan.

The easiest class, Mortal, is good for quick numeracy practice, and requires some logic and a basic understanding of cZeus rules to be solved. 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 and Olympian are challenging, while Titan is 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.
