18 people eliminated 6 people in the form of poems. How to design the scheme?

If it is an entertainment competition, draw lots to sort it out and form a circle. Whoever can't catch it will be eliminated until there are 12 people left at the scene.

If the strength is pure, you can get a responder who will take the lead. Deduct one point if it is correct, and eliminate the last six according to the score if it is wrong or repeated.
