Greenstreet Mathdoku - the PC version of the popular mathmatical puzzle craze. Countless randomly generated puzzles to get your teeth into, from really easy ones to fiendishly difficult!

Addictive and fun the rules are simple - The numbers in each outlined set of cells (called cages) must combine (in any sequence) to the answer shown in the top left hand corner of the cage using the mathematical operation indicated. (eg: for a cage containing 3 cells with the answer "12+" the value of each cell in the cage when added together in any order must equal 12, for a cage containing 2 cells with the answer "3-" the value of one cell subtracted from the other must equal 3.) The puzzle is completed when there are no more unknown squares. But don’t worry you don’t have to be a mathematical genius to play, although simple mathmatics is part of the game. Don't forget you can start off easy and build up your skills!

Hours of challenging fun for all ages & ability levels!
