One Up, One Down
One Up, One Down is a find-the-hidden-rule puzzle in which the leader points at people and labels each one "one up, one down", "two up" or "two down", and the group has to work out what the labels refer to. It is a traditional camp and party riddle with no known originator. In the version published by playmeo the key is the position of each person's feet; other tellings use the arms.
Facilitation script
- 1
Seat the group in an open circle and explain the three labels and the task of finding the rule.
2 min - 2
Label six to eight people in turn, asking for predictions before each answer.
3 min - 3
Keep going; ask solvers to stay quiet about the rule and prove it by predicting.
3 min - 4
Make the hints more obvious until almost everyone has it, then reveal the key.
3 min - 5
Short debrief: what were you watching at first, and what made you look elsewhere?

Tips
Decide the key in advance and apply it strictly; one inconsistent label makes the puzzle unsolvable and the group will stop trusting it.
Watch the people who have not solved it yet and increase the hints before frustration sets in, since being among the last three is uncomfortable.
People naturally look at faces and hands first, which is useful material if you want to debrief on assumptions.
Common pitfalls
Labelling inconsistently because you misread someone's feet, which sends the group after a pattern that does not exist
Letting an early solver blurt out the rule, which ends the game for everyone else before they had a chance to find it
Dragging the game on while two or three people remain stuck, turning a light puzzle into a public test for them
Staring at people's feet while labelling, which gives the key away in the first minute
Presenting it as an intelligence test instead of an observation game, so that people who solve it late feel judged
Variations
Arms key: the label follows whether a person's arms are raised, lowered or one of each, as recorded in other tellings of the game. Legs-crossed family: the same puzzle structure sits behind Spoons, where the rule concerns how the passer is sitting and not how the objects are passed. Remote: use a key visible on camera, such as hands in or out of frame, and take predictions in the chat. For larger groups, let those who have solved it take over the pointing and labelling.
Where it fits
When to use it
As a warm-up before analysis or problem-solving work, to show how easily a group fixes on the wrong variable
When you have ten unplanned minutes, no materials and a seated circle
During the social part of an offsite, when people want a game and not a method
Before a conversation about unwritten rules, for example in onboarding, where newcomers face labels nobody has explained
With a group of 6 to 20, ideally 8 to 15, that already has enough trust to laugh about not getting it
When not to use it
The group needs physical energy; this is a seated thinking game, so use Jump In Jump Out or Shake Down
Several participants already know the game or have just played Spoons; they will solve it at once and the rest will feel slow
Psychological safety is low or people are worried about looking foolish in front of managers; being last to solve a riddle is exposing, and a cooperative task such as Count Up is kinder
The group is larger than about 20 or people cannot see each other's feet, for example behind tables or on a video call without an adapted key
Time is tight; the game cannot be cut off halfway without leaving some people frustrated

Frequently asked questions
What is One Up, One Down?▾
One Up, One Down is a group riddle. A leader points at people and calls each one "one up, one down", "two up" or "two down" according to a secret rule, and the group has to work out the rule from the examples. In the best-known version the rule is about whether each person's feet are on or off the floor.
What is the answer to One Up, One Down?▾
In the feet version, both feet on the floor means "two down", both feet lifted means "two up", and one foot on the floor with the other raised, as when legs are crossed, means "one up, one down". Other traditions use the arms instead. The leader can choose any key as long as it is applied consistently.
How is it different from Spoons?▾
Both are hidden-rule games solved by noticing something about the people and not about the obvious action. In Spoons two objects are passed and declared crossed or uncrossed, and the rule is the passer's legs. One Up, One Down uses no objects, has three labels and the leader does the labelling.
What is the point of the game in a workshop?▾
Beyond being a low-effort break, it demonstrates how a group commits early to a theory and keeps testing it while the answer is in plain sight. That makes it a quick lead-in to work on assumptions, root causes or unwritten rules. Keep the link brief; the game is an illustration, not evidence.
How do you stop people from feeling left out?▾
Ask solvers to keep the rule private but to help by predicting aloud, and make your own hints steadily clearer so that nobody is stuck for long. End the game by revealing the key once only a few people remain, instead of waiting for the last person to get it.
