Do you pick up your face-up cards or play them off the table?
Verdict: in the official rules, when the deck is gone and your hand is empty, you pick your three face-up cards up into your hand. The more widely printed version has you play them one at a time straight off the table. This is one of the quieter splits between tables, and one of the most interesting.
What picking up changes
Playing face-ups off the table means three forced, visible plays. Picking them up gives you a real hand again: you can combine them, sequence them and spend them with the rest of your late game. It makes the pre-game swap a genuine investment, because the cards you bank at the start come home when the endgame begins.
Our ruling
Pick them up. Skill should peak at the end of the game, not run out before it. Playing face-ups from the table is a house rule.
