Bill Please!
Three people check into a hotel. They pay £30 to the manager and go to their room. The manager suddenly remembers that the room rate is £25 and gives £5 to the bellboy to return to the people. On the way to the room the bellboy reasons that £5 would be difficult to share among three people so he pockets £2 and gives £1 to each person. Now each person paid £10 and got back £1. So they paid £9 each, totalling £27. The bellboy has £2, totalling £29. Where is the missing £1?

Fillomino, hide and seek
Well, I've finally cracked it, after about twenty attempts (no really!) I've finally come up with this lovely little fillomino. Good Luck!
Authors Note
The area with the middle nine really was a tough nut to crack, the variety of the givens limited me so much that at one point I almost gave up, but this puzzle uses some really nice logic so I went with the nine for reasons that will become obvious upon solving.
Masyu, Boxed in?
Well, I don't think I seen a masyu quite like this before, you'll see what I mean when you come to solve it. By the way, entries have been recieved for the competition, and the winner will be announced next week, for a chance to have your puzzle on this site, follow the link below.
Don't delay time's almost up!

Masyu Competion Update
Right, well I've had a laugh today concering my challenge (http://puzzlevalves.blogspot.com/2010/02/maysu-trial-puzzle-valves-challenge.html). Now when I said there was not size limitations, I kinda thought that a minimum size would be sought, (eg. 8x8). However, upon opening my e-mail box today I found these...

It's called LITS, remember the name
A Special Heyawke
Well my attempts at a symetricallly arranged Heyawake have yielded this puzzle a nice puzzle, easy in parts, not so easy in others, with no shortcuts past the... not so easy bits, it should prove a challenge in a small package!
Authors note
This puzzle was a hard puzzle to design. Although I could whip out a decent design quickly, getting it so that people had a bit of a challenge whilst solving proved to be quite hard, at least if it were to be a puzzle of any difficulty at all!

Oooh, Torodial Sudoku
OK folks here's a challenge for you, a torodial sudoku, if you haven't solved one of these before then I recommend giving the much easier one attached to the rules a try first! These, like sudoku, have 1-9 in each row and column and nonet, but unlike sudoku they wrap around the sides of the grid!
Good Luck, you're gonna need it!
