Hi,lissy.
Here is a hint for 20:

Think about mirror

[melville]

20/21

Hi Lissy and Idezaki welcome back!

For 21:

Think about another number. I didn't find any logic though

Well perhaps I did find a logic for level 21:

Think nine-based number system

[idezaki]

Thanks melville. I'll try it.

[melville]

I pm'd you too Idezaki

[idezaki]

thanx melville. I got it!

[melville]

Well I can use some help with level 22. Still stuck

[idezaki]

I can't see anything. it seems no clue in propaties & source.
where shoulld i see?

[melville]

22

Well, all I can see is a minus sign? Or an underscore? Or perhaps you are right and it is ment to be nothing.

I tried ascii code: minus sign = 45 next sign = ' (a point and then I thought: 22-23 = -1 or the other way around = 1 wich brought me back to the first level of the a riddle lol) but nothing worked

or perhaps it is the end of the riddle?

what you can see in the sourcecode is a space symbol underscored (by stylesheet h1):  

[idezaki]

I've tried the methods that you gave me, still no luck *sigh*
I think it's temp end maybe
anyway,I'm going to try another one for a while.

[melville]

Okay, lots of luck, see you

Still stuck myself
