Stage 7 of LOGOSGBITS: seven trials in the fallacies — and not one of them is new. A term that shifts, a circle, a division that leaks, a universal overreached, a target missed: each is a fault from a stage you have already mastered, now met in the wild and given a name.
Each trial is locked until you clear the one before it. Every level scores out of 1000 — 600 for accuracy, 400 for speed — so speed alone can't clear the bar; you have to solve most problems, and quickly. Reach 650 to unlock the next.
You can catch a word changing meaning mid-argument, a conclusion hiding in its own premise, a choice with the middle removed, a universal built on two cases, and an attack aimed at the arguer instead of the argument — and say in each case exactly what went wrong and where.
