My Perspective

Visual perception accomplished in our brains is a fascinating process. There are many interesting features that one comes across. One of them is the visual search problem - the objective is to identify an odd image amidst a group of distractor images in the shortest time. Put differently, certain kind of symbols are more easily recognizable when placed amidst a group of similar looking symbols whilst others are not. For instance - symbol 'V' amidst symbol '^'s (inverted V) are very easy to spot. On the other hand, symbol 'S's are much more difficult to spot amidst symbol '2' (mirrored S). I could personally relate to this phenomenon while solving a 3x3 Sudoku in the shortest possible time.

Continuing with the tactics for solving Sudoku from my earlier post, here is the second part of the post. Here we will discuss tactics referring to level 2 and 3. For legend and terminologies please refer the earlier post . Level Two : The tactics are quite elementary, in that one would observe that these are applied to almost most of the sudokus of difficulty levels greater than two. These are also very easy to calculate and present a very powerful and easy tool to solve the tactics.

Sudoku, the puzzle of this decade ,  is quite a fun to solve.! But if you find it boring and think it is fun only as long as one can solve it.. then do take my word.. "Sudoku is lot more fun to solve when it gets harder , but only if you have the right tactics and solving strategies."
