It is assumed the user understands the impact of the findings listed here:
(With 51 remaining) in Group 9 I found two 1/7 pairs; in Column I there were two 4/8 pairs. This led to I3 not possibly being a 3, and so H2 = 3. Also I3 could not be a 5, so I3 = 6.

PB Post 2014 03 20 w 43 This is the same puzzle as above except the blue boxes are filled in.
In order to proceed, notice that along the top 3 groups (rows 1,2, and 3), the middle group has 2's available only in row 1. This means that both 2's in Group 1's top row can be crossed out. That leaves C3 = 7.
This is a "one-line elimination"
Another "one-line elimination" can be found looking at the 6;s in Groupo 3. They are only available in column H. Therefore, the 6's directly below them in Group 9 (H7, H8, and H9) can be eliminated. Sadly, this doesn't make any answer pop out, but in time it will help.
Solving the puzzle now requires only hidden and naked singles.

Pretty simple. When I had 24 remaining, I noticed the 1's in group 3. This allowed Single-Line Elimination of 1's from E2.
Then E2=6. FINIS.

Only naked and hidden singles were employed to fill in the blue boxes below:
The puzzle above opened with 15 naked singles, then some hidden ones: 2, 5, 6, two 7's, and a 9.
PB Post 2014 04 10 w 30 This is the same puzzle as above except the blue boxes are filled in.
Even an AVERAGE player should not require hints, but nevertheless:
To continue, notice in Column F the two 1/5 doubles allow elimination of 1 and 5 elsewhere in Column F.
In column E, a single line of 4's in Group 2 allows elimination in the group below it.
Soon in row 6 you can find hidden 4.
Then two 6's are found.
Then all the 3's are found. Easy finish.

PB Post 2014 04 17 w 31 This is the same puzzle as above except the green boxes are filled in.
Up to this point, only naked and hidden singles were employed to fill in answers.
Look for Single Line Eliminations of 3, of 8, and of 9.
Next, in Row 7, notice the 1/5 doubles. This proves that B7 cannot equal 1, and so it equals 9. Then A7 = 3.
The final 29 answers are naked singles.

Blue boxes were filled in using only naked and hidden singles.

Notice in row 6 there are two 3/6 "doubles". This allows you to remove 3 and 6 from OTHER boxes of row 6, proving that C6 = 8. Then B6 = 2; More singles appear.
With 34 remaining, look at columns G and H for Single-line eliminations of 3. You end up with row 4 having only a single 3, in B4.
Finally, Row 5: the 1/6 doubles prove that E5 = 4, then I5=7.
Keep working to finish.

The puzzle opened with a single naked 2. After that, ALLthe 3's and 4's were found, mostly as hidden singles.
With 42 remaining (14 done) notice 1/7 doubles in groups 5 and 7.
With 40 remaining, see Row 2: 1/8 doubles reveal F2=7.
With 37 remaining, Column H, note single line eliminations of 9.
Then in column G, note 1/8 doubles reveal G3 = 5.
Enough!
