World’s most popular puzzle Sudoku has a new variant available in the market. The new version called Chain Sudoku was released by Conceptis recently.

Chain Sudoku is the same game with a new twist. Even the rules of playing remain the same. The new version is now available for all media including books, magazines, newspapers, online gaming and even mobiles and other electronic devices.

The new variant’s games are very much similar to normal Sudoku. The twist lies in the grouping of the numbers which are now to be grouped in chains than in boxes. The new form enables these puzzles to be developed in sizes of four by four to nine by nine. The graphic appearance of the puzzle also remains the same.

The randomly shaped chains offer a number of possibilities of logic requiring situation and basically enhance the brain-usage experience.
