Build a Haskell Game related to Jigsaw Sudoku -- 2

Specification is described in the file. I need 2 different implementation (do not simply changing variables name, which is not 2 different implementation, the implementation logic needs to have slightly differences for 2 implementations)for the same Haskell game. For the Extra Features part. I want you to implement 2 differences extra feature for each of the copies. The extra features cannot be repeated. 2 different short final report is required, as described in the pdf. Needs to comment the codes.
