Q&A for How to Play the Card Game Speed

If there are no more cards, you should reshuffle both stockpiles, place them in the side piles, and continue to play from there.

Only if you are putting it on the other active pile, because the card laid must be either one up or down from the pile you are laying on. For example, if you have two jacks in your hand and the active piles each have a ten or a queen, then you can lay both jacks down, one on each pile.

When you play more then one card at a time it is called stacking. Some people like to play with stacking and others don't. Before starting a game you should ask your opponent if you want to play with or without stacking.

If they are not currently in your hand, you should not look at them yet.

In traditional Speed, a duplicate cannot be played (for example, no Jack on Jack.) However, many players prefer to play doubles, in which this is allowed - just clarify with your opponent before the game starts, so you two can establish whether or not doubles will be used in that round.
