Rules As Written

Rules As Written
A court of words. Every rule in play is a sentence built from six word blocks:

At the end of each turn, the OWNER gains 1 POINT.
It is your rule and it pays you. Then your rival plays a single word card onto it:

At the end of each turn, the OWNER'S OPPONENT gains 1 POINT.
Same rule. Same table. It pays them now, and it will keep paying them until someone changes it again.

That is the whole game. You lay rules, you rewrite theirs, and they rewrite yours back. Nothing on the table is safe, including the win condition: that is a card too, sitting at the left of the table, and for two favour you may change one of its words. 

The player with the MOST POINTS wins, once anyone has ten. Unless, on the last turn before the court reads it, somebody makes it the FEWEST.

A duel, in about ten minutes
Lay a rule. Six blocks, a plain English sentence, and a line underneath telling you exactly what it does to each player right now.
Change a word. Word cards are drawn, not chosen, so you play the loopholes you are dealt.
Object. When your rival ends their turn, you get one window to play a single word onto a rule that is about to fire. Hold something back for it.
Read the card. When anyone hits the threshold the court adjourns, everyone gets one final turn, and only then is the win condition read as it stands.

What is in this prototype
Eight rivals, each with their own deck and habits. The Pedant corrects your quantities. The Hoarder wants the biggest hand. The Magistrate rules in its own favour.
199 cards: 79 rules, 59 actions and 61 word blocks, unlocked as you climb the ladder.
A tutorial that takes about five minutes and ends with you stealing a duel you were losing.
Practice mode, on by default: a hint button that tells you what the strongest rival would do in your seat.
A deck you draft. Every win offers three cards from what you have unlocked; take one, cut one if you like. Three losses end the run and the deck resets, the unlocks stay.
Pass and play for two to four people on one screen.
Phones work in landscape, drag to play, swipe to scroll.

What I would like to know
This is a prototype and I am looking for whether the idea has legs.
Did the moment you first rewrote a rival's rule land?
Did you ever change the win condition, and did it feel clever or cheap?
Where did you get confused?
There is a COPY COURT RECORD button in the menu. It copies the full transcript of your duel to the clipboard. Paste it with your feedback and I can see exactly what happened
