Line-Up - 1v1 Face Line-Up Memory Duel
Line-Up on FlagDuel is a free 1v1 memory duel: three faces are shown one at a time for 0.9 seconds each, a line-up of six faces then appears and you tap exactly the three you were shown, a wrong face locks your board for 0.7 seconds, and the first player to complete 3 line-ups wins the round.
Three faces, one after another, nine tenths of a second each. Then six faces in a row, three of which you have just met, and all you have to do is say which.
Recognising a face is something people are remarkably good at, and describing one is something they are remarkably bad at, which is why this plays nothing like remembering a list. There is no rehearsing a face under your breath and no chunking it into pairs. It either went in whole or it did not.
The three you have never seen are there to make sure of it. A wrong face locks your board for 0.7 seconds, and three completed line-ups takes the round.
How to play

SoonFrequently asked questions
Is remembering a face a different job from remembering a shape?
It is handled differently and it feels different. Faces are taken in whole rather than as a list of features, which is why you can be certain you have seen someone and unable to say one useful thing about them - and why a face turned upside down suddenly becomes as hard to place as a random pattern.
How much can a guess win me in a six face line-up?
Not much. Picking three out of six at random comes good about one time in twenty, and every wrong face costs 0.7 seconds before you can try again. Six is chosen to be exactly that awkward: too many for luck to be a plan, few enough that three faces held properly are all you need.
Is the line-up judged as I tap or after three picks?
As you go. A correct face stays picked and a wrong one locks you where you stand, so the line-up is finished the moment your third correct face is in. There is no submitting a set of three and hoping - every tap is its own claim, and it is answered immediately.
Does a 0.7 second lock cost me the faces I am still holding?
Often, and that is the sharpest part of the penalty. Sitting out three quarters of a second with two faces half-held is long enough for one of them to slip, which is why the second mistake in a line-up tends to follow the first so quickly. The players who survive it are the ones who tap without deliberating - a face you are still thinking about is a face you are already losing.
