Compile: Main 1

You may play a card face-up only into the line matching its Protocol, but you may play a card face-down into any line (face-up cards must match their Protocol when played) (p.1).

During the Check Compile step, if you have 10 or greater value in a line and that value is greater than your opponent's in the same line, you must Compile that line as your sole action; you may only Compile one line per turn even if you qualify for more (pp.1–2).

Covered cards still contribute their Value (the rules require Value be visible when covered), but only the most recently played (uncovered) card in a stack can be manipulated unless an effect specifically references “covered cards” or “all cards” (p.2).

If you have higher value than your opponent in at least two lines you gain the Control component; when you have it you may first rearrange one player's Protocols before Refreshing or before Compiling, after which Control returns to neutral (p.1–2).

Recompiling (compiling a line whose Protocol is already Compiled) still deletes all cards in that line, but instead of flipping the Protocol you draw the top card of your opponent's deck (p.2).

On your Action you may either play one card or Refresh; if you don't have any cards to play you must Refresh, drawing up to five and reshuffling your trash into your deck if needed (p.1).
