Voldemort waved his wand and cleared the moss from the wall beside the stone door. Only then did he see the game rules engraved in small lettering to the right of the recess.
[Rules: using the Reductor Curse, Blasting Curse, or any spatial displacement magic to forcibly dismantle the puzzle is strictly forbidden. Challengers must use their wands to guide the sliding blocks through this confined space, maneuvering them into position to help Salazar break through the encirclement and escape intact through the Power Door at the bottom.
A true schemer never wastes a move. The total number of moves must not exceed 80.]
Voldemort looked at these game rules and sneered.
"Using such a cheap little trick as a trial of Slytherin is the shallowest, most vicious insult imaginable to pure-blood heritage and the wisdom of Dark Magic."
Still, he had no intention of destroying it outright. Instead, he silently set himself a time limit: one minute. No, three minutes. He would solve this ridiculous toy as easily as crushing a stinkbug, then see what colossal piece of rubbish that presumptuous Ravenclaw at the entrance had hidden away.
He raised his wand. To move the [Salazar Slytherin] at the top southward, he naturally ought to reposition the bulky, highborn [Pure-blood Allies] and [Ancient Contract] beside him first. As for the four filthy little stones below, engraved with [Stupid Muggles] and [Muggle-born Wizards], he could simply sweep them into dead corners and bury them like rubbish.
Click, click.
Without hesitation, Voldemort pushed the two single-square stones at the bottom, engraved with [Muggle-born Wizards] and [Stupid Muggles], into the two bottommost corners, then tried to pull the horizontal [Ministry of Magic Wizengamot] block above them straight down.
Yet fewer than ten moves later, a dull clunk came from the stone recess.
