Yes. As players begin to master the game they start to understand the cards and what they do.
A player can simply state/say what card they want to play (i.e. TURN RIGHT). Alternatively they can lay the cards out in front of them and simply point to the INSTRUCTION card they want to play. It is really up to the players how they want to issue their INSTRUCTIONS – but bear in mind the normal rules apply.
If a player is playing the FUNCTION card or is playing the Advanced game then they need to lay out the cards in front of them so it is clear to all players what they are trying to do (when developers actually code it is important for them to add commenting to their code so anybody else reading the code understands what the code does – by ensuring players do lay out cards in front of them when performing an advanced move, like playing a FUNCTION card, so all players can understand and learn from it).
