Spoiler Alert

This CAD model was designed by Oskar van Deventer, copyright (c), 20 December 2025.

Spoiler Alert was proposed by Kevin Sweer. The goal is to remove the coin from the triangle. The puzzle comes with a big spoiler alert. The puzzle is arguably the world's most easy puzzle to solve. Nevertheless, nobody has yet managed to solve it without reading the spoiler first. Can you solve it without reading the spoiler?
