About the game
Mindline is a guessing game about how other people think. One player sees a secret spot on a line between two opposites, say Tiny and Enormous, and writes a short clue; everyone else drags a slider to where they reckon it sits. It plays 2 to 16, but it is at its best with 4 to 8, when the guesses spread out and the arguments start. With one clue each, a game lasts about 15 minutes.
Use a TV if you have one, so the room sees every guess land at the reveal. Without one, pick "Just this screen" and the line, the clue and your slider all sit on your own device. That also makes it easy to play over a video call.
How to play
- Take turns giving clues. Only the clue-giver sees a secret number on a line between two extremes, such as Freezing and Scorching.
- If the target is 78, a clue could be “fresh pizza.” Write a thing, place or idea at that position. Never say the number, a percentage or “far right.”
- Everyone else reads the clue, moves the slider on their own screen, then presses Lock guess. Guesses stay hidden until everyone locks in or time runs out.
- The TV reveals the target and each guess. Exact = 10 points; 1 to 5 away = 9; 6 to 10 away = 8, and so on. No guess = 0. The clue-giver gets the group’s rounded average.
- Then the next player gives a clue. Everyone gets one turn per lap. Highest total wins; ties share the win.

Tips to play well
- The secret number is always between 10 and 90, so the very ends of the line are never right. If a clue feels extreme, try 85 rather than 100.
- Close counts. Within 5 of the target still earns 9 and within 10 earns 8; you only score nothing when you are more than 45 away. Always lock something in, because a missing guess scores 0.
- As clue-giver you score the rounded average of everyone's points, and a player who never locks a guess counts as 0 in that average. Aim for a clue the whole room will place, not one only your best friend will get.
- Clues can be up to 80 characters with no digits or percent signs. If clue time runs out, the turn is skipped and nobody scores for it, so send something rather than polish forever.
Host settings
- Clues per player: 1 to 3, default 1. Each lap gives every player one turn as the clue-giver.
- Clue time: 20 to 90 seconds in steps of 5, default 45.
- Guess time: 15 to 60 seconds in steps of 5, default 30. The reveal comes early once everyone has locked in.
Questions people ask
How does Mindline compare with Wavelength?
It is our own take on the spectrum guessing style: a hidden target, one clue and points for getting close. Here every guesser has their own slider and their own score instead of one shared dial.
How many different lines are there?
There are 20 pairs of opposites, and a game does not repeat one until all 20 have been used.
Can we add computer players?
Yes, the host can add bots. A bot gives one of the game's stock example clues and guesses the middle when it does not recognise yours, so it fills a seat but will not out-think anyone.
Is it free?
Yes. The host opens a room for free, and guests join with the four letter code without paying or signing up.
