The last one was pretty messy. This one should be nicer. I quite like this one. Shouldn't be too hard, but hopefully requires some thinking.
Three at a time
Standard sudoku rules apply.
Digits in a cage must sum to the small number at the top of the cage.
Digits along a thermometer must increase from the bulb end.
Both of the main diagonals must contain no repeated digits.

Okay everybody. It is time for this town to get down. On January 10, I will draw for the winner of a copy of Cracking The Cryptic's Greatest Hits. To get an entry into the draw you just have to send me a solved grid for one of the puzzles I have created and posted in this thread. You get one entry for EACH puzzle you have solved.
Once the winner is drawn, I will post the name here, and contact that person by PM to get a mailing address. I will state now that there are some errors in the book, despite much reading and proofing by the publisher. I will send what errata I have been given in a PM.
Below are the puzzles which are part of this contest. Under each puzzle I will note who has sent me a correct solution. If you think you have solved a puzzle and I have missed that, PM me and we will try to fix that.
For the Arrow Sudoku, I have a solution from Onuzq only.
I don't seem to have a solution from anyone.
Solutions from ArcticKnight and Onuzq.
I have solutions from ArcticKnight, Onuzq, and bolt2112.
I think only ArcticKnight has submitted a solution.
It seems only Lattimer has sent a solution.
I have a solution from ArcticKnight.
ArcticKnight, Lattimer, and Onuzq did this one.
ArcticKnight has sent a solution.
ArcticKnight solved this one.
ArcticKnight submitted a solution.
ArcticKnight and Onuzq submitted solved grids.
ArcticKnight has submitted a solution.
I don't seem to have any solved grids for this one.
ArcticKnight and Onuzq, again.
ArcticKnight solved this one.
I have received a solution from Onuzq.
None yet, but this is not a great one anyway.
ArcticKnight and Onuzq sent in this one.
So it looks right now like AK has 13 entries, Lattimer has 3, Onuzq has 9, and bolt has 1. I have given everyone who did anything with my Quarks puzzle an entry, because that was poorly done on my part. I have gone through my PMs to find out who has sent what. If you think you sent me something that I haven't acknowledged, please send it again if you can.
There is also time for players to catch up, as I will do the draw on January 10.
A great big thank you to everyone who has tried my puzzles, and thanks for all the feedback.

For those who do not know, an Arrow Sudoku has circles in the grid with arrows coming out of them. The sum of the numbers on an arrow is the number that goes into the attached circle. Otherwise, normal sudoku rules apply.
A clarification about my puzzle is that there are some squares which are on more than one arrow, and it is hard to show how the intersecting arrows are supposed to flow.
In the top right 3x3 block, the arrow that starts in row 2 column 9 goes left one square then turns up. The other arrow turns down at the intersection.
In the bottom left 3x3 block, the arrow that starts in row 8 column 1 goes right one square then turns down. The other arrow turns up at the intersection. I'm sorry if it is confusing
Here is the link to the f-puzzles site so you can solve it.

The Arrows Are A Bit Dotty
I’ve been playing around with multi digit arrow totals, and not getting what I want. However, some of what I’ve been exploring is in this puzzle.
Standard sudoku rules apply.
Cells separated by a black dot are in a 1:2 ratio; cells separated by a white dot are consecutive. Not all dots are given.
Bi-directional Arrow rules: the cells along an arrow must sum to the one- or two-digit number in the circle or pill – Read In The Direction Of The Arrow.
Be aware that the f-puzzles software does not like the bi-directional arrows, so it may tell you something is wrong, when it may not be. If you don’t solve it with f-puzzles, there won’t be this problem.

Lines, Lines, Lines: I won't submit for this because I genuinely need to be shown where the break-in is after this point. I cannot see it and have spent upwards of 75 minutes at this position. I have not done any renban puzzles before so I'm sure there are a few simple things to think about that would help me unravel this.
