Make your argument, read the court's reaction, and deduce the principle the case truly turns on.
Each case has a hidden governing principle. Play argument cards and the Bench responds: green means you found the principle and win, amber means a related thread, grey means off-point. Use the feedback to rule out principles and win with the fewest wrong arguments.
Bench teaches constitutional principles through guided trial and error, building reasoning about rights and the courts.
Playing argument cards and reading the Bench's green, amber or grey response is an appellate hearing, and the hidden governing principle is the case's ratio.
Grading arguments as on-point, related or irrelevant is the original feedback.
That grading is what precedent means in practice. A case is decided by the principle it turns on, so an argument can be true, well made and still grey because it addresses a different question — which is the distinction between being right and being relevant.
Bench is an original legal deduction game that teaches constitutional principles through guided trial and error. It is free to play in your browser with daily and practice cases.
