How can I set up a game of the Resistance without anyone needing to close their eyes?
This solution would work, though it may take a minute to perform. For p players, with t traitors and n &quot;normals&quot;, you need:

t &quot;You are a traitor&quot; cards and n &quot;You are a normal&quot; cards, obviously
p &quot;player&quot; cards marked with unique colours (or numbers or whatever)
1 card with an identical back to the player cards and a blank face (a kind of joker)

Deal each person a &quot;Traitor/Normal&quot; card so they know their faction, then the process is:

Everyone takes a coloured &quot;player&quot; card. Show them publicly since they identify each player.
Everyone holds their player cards with their hands under the table.
The first player takes the blank card face-down under the table too.
Players will pass the spare card around under the table, BUT, if they are a traitor, they will instead pass their own player card.
Once the spare card gets back to the leader, he should keep it face-down on the table, since it reveals the identity of a traitor! Then, everyone secretly looks at their card. Normals will see their own card again, of course, but traitors will see the card of one other traitor (or the joker if they were the first traitor).
Perform steps 4 and 5 a total of t+1 times.
Now all players (including traitors) should have their own cards back and the leader can flip the joker to reveal that it IS the joker. If it isn't, someone cheated/messed up. The traitors should have each learnt a new traitor's identity on each lap (except for one). Everyone should reveal their colours again to remind everyone what they were (though it's only relevant for traitors).

A detailed example
Alan (Red), Ben (Blue), Chris (Green) and Dave (Yellow) are sitting round a table. Ben and Chris are traitors. Alan, the leader, takes the joker and, because he is not a traitor, passes it to Ben. Ben IS a traitor so he keeps the joker and passes his own card to Chris. Chris - a traitor - keeps Ben's card and passes his card to Dave, who, being a normal, passes it on back to Alan. Alan puts it face-down to one side.
Everyone looks at their cards. Alan and Dave see their own. Ben sees the joker (so he can already deduce that Alan is not a traitor). Chris sees the blue card (Ben's), so he knows his co-traitor.
Alan now takes the face-down card (Chris' green card) and passes it again. After they repeat the process, Ben has Chris' card and Chris has the joker. Then they perform the rotation one more time so that the traitors both get their cards back and the joker is flushed out.
Everyone reveals their coloured cards and Chris confirms the owner of the blue card, while Ben confirms the owner of the green card. The game begins.
