The basic rules are equal to standard Sudoku but you have to work with elementary arithmetic rules or just by bigger/smaller arrows and grid sizes starting from 4x4 to final 9x9.
Took me over 10 hours to master all challenge puzzles, the campaign of the game. Over 19000 puzzles remaining just for fun. i.e. 98% undone.
Well worth the steam sale prize.
Everyone who likes Sudoku should try the demo.
