This topic collects results for pass/fail challenges, i.e. ones where we ask "Which levels are possible with a given condition?" and don't have a numerical component to the results. These tend to give rise to shorter topics than numerical challenges, simply because there is no room for improving on existing results, so after a discussion on discord we decided to combine them into a single topic. If any of them become popular enough to move on to other packs beyond Redux, we can split them out into separate topics, but for now, we'll combine them and see how it goes.
And now, on to the results!
