Sudoku
This popular Japanese game (su = number, doku = single/unique) has now extended to other countries as well, and it requires logic and concentration.
The rules are pretty simple: you must complete all free cells (in our case the '-' signs) with numbers from 1 to 9, so that each row, each column and each 3x3 area separated by the grid (in our case the '+' signs) has all numbers from 1 to 9 and only once. Each Sudoku game has only one unique final result.
There are a lot of levels of difficulties, based on the amount of numbers that are predefined and how these numbers are placed.
Here's how we'll play: I give the first game and whoever finishes it first gives a new one (if there's any problem - e.g. can't find a Sudoku game - I'll give it; I have A LOT of Sudoku games)
Oh, and don't get upset if someone finishes a Sudoku game when you have 90% of it done. This is no competition, we just do it for fun, right?
Ok, here's the first one (it's pretty easy, but for those that never played Sudoku it might be hard)
- - - + 4 2 8 + - 6 -
9 6 8 + - 3 - + - - -
2 - - + - - - + 3 8 7
+ + + + + + + + + + +
- - - + - - 5 + 7 4 6
- - 6 + 7 - 3 + 2 - -
1 2 7 + 8 - - + - - -
+ + + + + + + + + + +
6 3 4 + - - - + - - 1
- - - + - 6 - + 8 2 5
- 8 - + 9 7 1 + - - -
Note, if you post a Sudoku game use the [courier] [/font] stuff, so that the text has a fixed width.
I'll give some tips: first, never GUESS. Place a number only when you're sure it fits in the appropriate place.
Now some practical tips:
Let's analyze the Sudoku game I gave above. Let's look in the 3x3 area in the upper-middle. Let's try to place the 7 number, but where? As you can see, there is only one place you can place it because otherwise you would have two 7s either on the fourth column from the left or the third row from up. So we place it where it belongs:
- - - + 4 2 8 + - 6 -
9 6 8 + - 3 7 + - - -
2 - - + - - - + 3 8 7
+ + + + + + + + + + +
- - - + - - 5 + 7 4 6
- - 6 + 7 - 3 + 2 - -
1 2 7 + 8 - - + - - -
+ + + + + + + + + + +
6 3 4 + - - - + - - 1
- - - + - 6 - + 8 2 5
- 8 - + 9 7 1 + - - -
Now let's look for an 8 in the lower-middle area. There's only one place where it can be written because otherwise it would be two 8s on the 4th and 6th columns.
- - - + 4 2 8 + - 6 -
9 6 8 + - 3 7 + - - -
2 - - + - - - + 3 8 7
+ + + + + + + + + + +
- - - + - - 5 + 7 4 6
- - 6 + 7 - 3 + 2 - -
1 2 7 + 8 - - + - - -
+ + + + + + + + + + +
6 3 4 + - 8 - + - - 1
- - - + - 6 - + 8 2 5
- 8 - + 9 7 1 + - - -
I hope those are enough tips to get you started (PS: I can post easier Sudoku's as well)

That's right
But use the [courier] [/font] tags next time
And spaces between each character to make it more readable.
Like this:
[courier]
3 7 5 + 4 2 8 + 1 6 9
9 6 8 + 1 3 7 + 4 5 2
2 4 1 + 6 5 9 + 3 8 7
+ + + + + + + + + + +
8 9 3 + 2 1 5 + 7 4 6
4 5 6 + 7 9 3 + 2 1 8
1 2 7 + 8 4 6 + 5 9 3
+ + + + + + + + + + +
6 3 4 + 5 8 2 + 9 7 1
7 1 9 + 3 6 4 + 8 2 5
5 8 2 + 9 7 1 + 6 3 4
[/font]
Next Sudoku:
8 - - + - - 4 + - 2 -
3 - - + - - 1 + 8 7 -
9 - - + - 5 8 + - 1 -
+ + + + + + + + + + +
- - 7 + - 3 - + 1 4 -
- - 8 + 4 - 2 + 6 - -
- 2 1 + - 9 - + 5 - -
+ + + + + + + + + + +
- 6 - + 1 8 - + - - 3
- 8 3 + 5 - - + - - 1
- 4 - + 2 - - + - - 9

@eugen - I like your new Sudoku design 
I have a new 'special' Sudoku: it's called Sudoku Mosaic and, in addition to the normal rules, has one more: There are no adjacent cells from the same group. The groups are as following: Small (1,2,3), Medium (4,5,6) and Big (7,8,9). In other words, you can't have a 1 near a 2 or 3, a 4 near a 5 or 6 and so on...
NOTE: adjacent means only cells that share the same edge. A diagonal cell is NOT adjacent.

I don't know how hard this is, because you can 'guess' the correct number on the first try and solve it fast -- but that doesn't mean it's easy just because you were lucky.
Oh and one more thing: Don't cheat!

Now this is a really difficult Sudoku. It has the same basic rules (+ diagonals!), only that there are five Sudoku games present, and one of them overlaps the other four. You have to complete all free cells of all five, without breaking any rule respective to each Sudoku. The one that overlaps is delimited with red lines.
Now, what does the diagonals rule mean? Well, nothing special, only that you can't repeat the same number on the main diagonals (in addition to the normal rules). Here, an example of what the main diagonals mean:
- - - - - - - - -
\ /
- - - - - - - - -
\ /
- - - - - - - - -
\ /
- - - - - - - - -
\ /
- - - - - - - - -
/ \
- - - - - - - - -
/ \
- - - - - - - - -
/ \
- - - - - - - - -
/ \
- - - - - - - - -
Note that all five Sudokus have their own diagonals!
And now, behold!

I really don't like Soduku. Whenever I try to do them, the numbers are just in the wrong places and it never works out. They always annoy me.
