Choose one of 9 modes. On one phone, both players pick a map and pass the phone. Online, you pick only your own map; your opponent brings theirs.
Place your characters anywhere on your half of the paper. Spread them out, tuck them behind the sun, put one right on the crease. Your opponent never sees your side.
On your turn, tap where you think a target is hiding on the other half. The paper folds shut and your ink prints straight through the crease onto their side.
Hits stay marked so you can plan around them. Misses teach you the map. Take out every one of their characters before they take out yours.
Every mode changes the number of targets, the size of your ink, or the rules of the paper itself. Online, each mode has its own matchmaking pool.
5 targets each. See everything, mirror your aim.
3 targets, smaller ink. Fast and sweaty.
Targets are invisible. Probe, remember, deduce.
Survivors sneak to new spots every 2 rounds.
1 PHONE ONLYOne target each, big ink. One hit and it's over.
8 targets, tiny ink. A long, crowded fold.
Ink dries clear. Only your last 2 marks stay on the paper.
Two stamps every turn. Aim twice, fold once.
6 seconds to stamp, or the paper folds on its own.
1 PHONE ONLYSit across from someone and pass the phone. Each player sets up their half in private, then the paper flips to whoever's turn it is. Nothing to sign into, nothing to wait for. One-phone games are just for fun: they don't pay Ink or XP and don't count on the leaderboard.

Sign in to Game Center, pick a mode, and you're matched with the next player waiting in that mode's pool. You both bring your own map. The phone turns sideways: your half on the left, theirs on the right, with live usernames and characters. Every online fold pays Ink and XP, win or lose, and every win climbs the worldwide ranks.
