Tricky, hard, demanding, grueling, brutal
These five chips rate difficulty. Tricky suggests a puzzle that needs care rather than effort. Hard is the plain everyday word. Demanding means it takes steady time and energy, like a job or a course. Grueling is about physical or mental exhaustion over a long stretch. Brutal tops the strip; it is informal and fits a cruel schedule or a savage review.
