In most forums, various chain puzzles, for example, are located in the aforementioned section (if one exists).
For example, rpg-zone. It's a large forum where games of the "chain puzzles" or "A+B" caliber are placed in the off-topic section. Moreover, they are periodically deleted (this is related to the fact that the post counter is enabled everywhere).
Svyatolok (in honor of Lok)

Барон "Vampires"
Отдай свои прошлые сны,
В сомненьях себя обрети,
В бешеном танце душа кружится!
Не думай, что будет потом,
Здесь и сейчас мы живем,
Стань хоть на миг сам собой, слышишь!
