Thank you bunches! Contacted the creators in the hope they can provide new links and mean while I moved all three games to the broken links sections. I removed the link of real riddle 2 because the redirecting site is untrusted and possible dangerous.
I haven't dealt with your post of one week ago yet, but I will. (P.S. Kzin took care of the first one, but I guess he didn't spot your edits. )
