Argue before you are shown
You write your own answer first, from the seat you have chosen. Only then do you see what a strong answer from that seat contains.
Notice what you missed
A short checklist of points for each seat, each with the reason it matters. The hints point at an idea without giving the argument away.
Learn why people disagree
After each seat, see how the same moments in the case look to everyone else. Most disputes are not about facts. They are about where you sit.
How a session works
- Step 1
Choose a case and a seat
Read the facts and the working rules, then choose who you will be: for example the defence barrister, the buyer's conveyancer or the mediator.
- Step 2
Write your answer
Say in your own words what you would argue. You may ask for up to three hints, each pointing at a point you have not yet covered.
- Step 3
Tick what you covered
A checklist of the points a strong answer contains. Words in your answer suggest some ticks; you confirm or change them.
- Step 4
Read the result
Your score for the seat, what you missed and why it matters, what could have been done better, our version, and what changes when you change seats.
Questions
Who marks my answer?
You do. Nothing here reads or judges what you write. After you write, you tick the points you covered on a checklist, and the page only suggests ticks by matching words, which you confirm or change.
Is what I type sent anywhere?
No. Your answers and scores are kept in your own browser on your own device so you can come back to them. Nothing is sent to us or to any service. You can download your answers as a text file, and you can clear them at any time.
Are the cases real?
No. The facts and names are invented, and the roles are teaching roles. Each case is labelled with the legal system whose general principles it uses. They teach how to think from a seat, not what would happen in a real case.
Is this legal advice?
No. The working rules in each case are general and deliberately conservative. A real matter turns on its own facts and on the current law, and needs a lawyer.
Can I try it before paying?
Yes. The first cases are free to play with no account. The others are included with All-Access.

This tool teaches how to think from the seat of each person in a legal matter, using invented facts and general principles. It is not legal advice, does not predict the outcome of any real case, and the roles are teaching roles. Check the current law and take advice on any real matter.
