What is Sticker Ninja?
Sticker Ninja is a stealth game played across a whole event: every guest gets a full sheet of stickers, and the goal is to plant every last one on a different guest without getting caught in the act.
It works because sticking someone forces you to actually cross the room and get close — no small talk required, just proximity and a straight face. Get caught mid-stick and the target peels the sticker off and hands it right back; miss it, and it rides along until the night's over.
Skip it for a room that doesn't want surprise physical contact, a crowd of strangers who haven't agreed to be touched, or any event where guests can't opt out easily — the whole mechanic depends on people being fine with an unannounced sticker landing on their arm.
The rules
- Every player gets a full sheet of stickers to place on other guests.
- Each of a player's stickers has to land on a different guest — no doubling up.
- Caught in the act? The target peels the sticker off and hands it back.
- Miss it in the moment, and the sticker stays put until the night's over.
- The first player to stick every sticker can call the win.
- A winner rounds up their "victims" so the room can confirm none went missing.
Before you start
- Group size: 2–50 players. Works with as few as two guests, but the bigger and more crowded the room, the more chaotic — and lively — it gets.
- Order sticker sheets ahead of time. 10 stickers a sheet is a solid ratio. Hand each guest a full sheet as they arrive, before the event gets going.
- Give every player different stickers. Different colors or designs per player make a win easy to verify, especially if there's a prize riding on it.
- Set the boundaries out loud. No stickers on TVs, pets, or anyone's private areas — say it before the sheets get opened.
How to run it
- Hand out the sticker sheets 2–3 min
As guests arrive, give each one a full sheet — 10 stickers is the standard count. For a version that's easy to verify, use a different color or design per player.
- Lay out the rules and boundaries 1–2 min
Explain before anyone peels off a sticker: they go on people, not TVs or pets, and nothing goes on a private area.
- Send everyone out to stick 8–10 min
Every sticker has to land on a different guest. A slap on the back, a distracted handoff, whatever it takes — subtlety is the entire game.
- Handle a catch 10 sec
Caught mid-stick, the target peels the sticker off and hands it back. Missed entirely, it rides along until the night ends.
- Call the win 1–2 min
First to place every sticker announces it, then calls their targets to the middle of the room so the group can confirm none quietly vanished.
