Either-or questions
Two sides, no wrong one. “Ramen broth: drink it to the end, or stop when the noodles are gone?” “It starts raining: buy an umbrella, or run for the station?”

How a round goes
You answer first. Your picks are locked in before anyone guesses, and nobody sees them until they have made their own call.
One link
When you finish, you get one URL. Anyone who opens it can play — a group chat, a 1:1 thread, a story link.
Friends guess
They pick the side they think you chose and see straight away whether they matched. Your answer is only revealed after each guess.
Score and ranking
One match is one point. The result shows their best and worst topic, the questions only they got right, and where they rank against everyone else on the same link.
Themed packs
Start with the main mix, or pick a pack for one side of your life. Themed packs run 10 to 40 questions; the main mix goes up to 80.
Main mix
Food, going out, habits, and values.
Love
Dates, crushes, couple habits, and what you want from love.
Dark
Honesty, envy, secrets, and late-night impulses.
Food
Meals, snacks, drinks, and taste calls.
Games
Play style, multiplayer, collecting, and session habits.
Oshi
Merch, lives, feelings, and how much you spend.
SNS
Posting, privacy, scrolling, and how you reply.
School
Class, homework, classmates, and school events.
Which side do people pick?
These numbers come from quiz creators’ own answers, not from friends guessing.

Sending it to a group? Use the friend page. Sending it to a partner? The couple page opens the love pack.
Friend quiz
Group-chat dare
Someone in the thread just said they know you best. Answer a mixed set of either-ors, drop one link in the chat, and let the ranking settle it.
For couples
Couple quiz
One of you answers the love pack. The other guesses which side you picked. You get a score and a topic breakdown — not a compatibility verdict.
Who it works for
Anyone who has watched you make small decisions. The questions are ordinary on purpose, so the score reflects attention, not trivia.
Close friends
Send it the moment someone says “I know you better than anyone.” Twenty questions settles it in a few minutes.
Group chats
One link, many players. The result page shows the group average, the top score, and the question almost everyone missed.
Couples and roommates
People who share a kitchen or a calendar get tested on the details: lights left on, laundry left in the basket, first alarm or three snoozes.
What the main mix asks
The default pack has 80 questions, 20 per topic. Every quiz draws evenly from all four, so a 20-question set gets five of each.
01
Food
Convenience-store lines, ramen broth, ice in the drink, and whether the last bite on a shared plate is fair game.
02
Going out
An open train seat, sudden rain, a long line at a famous spot, getting to the meeting place ten minutes early or right on time.
03
Habits
Phone charging, lights, laundry, snooze, browser tabs, and whether a drafted message sits overnight.
04
Values
How you apologize, what you do with a secret, and whether you offer a fix or just listen when a friend vents.
What the score tells you
Every question has two sides, so blind guessing lands around half. That is the line to beat. Each result also gets a title.
75% and up
“Knows too much,” or “Account admin” past 90%. They could have filled in your answers for you.
50–74%
“Coin-flip psychic.” Right on the obvious calls, guessing on the rest. The topic breakdown shows where it slipped.
Below 50%
“Group-chat NPC” or “Who even?” Usually they answered for the person they imagine you are. Worth a rematch.
Tips for a fair round
The score is only as good as your own answers.
- 1
Answer as you are
Pick what you actually do, not what you wish you did. If you snooze three times, say so.
- 2
Swap, don’t fake it
If a question does not fit your life, swap it while you answer. The replacement comes from the same topic when one is left.
- 3
Keep your picks secret
Do not screenshot your answers into the chat. Once one person sees them, the ranking stops meaning anything.
- 4
Match the length to the room
Ten is a quick dare. Twenty is the default. Forty or more is for the friend who says they could answer for you.
Group chat or one-on-one?
Both work. They just give you different results.
Group thread
Everyone plays the same link, so you get a ranking, a group average, and the question that tripped up the most people. More players, better spread.
1:1 chat
Good for a partner, a sibling, or the one friend who made the claim. With one player, the topic breakdown says more than the rank.
A party or a night in
Have everyone open the link at the same time and compare at the end. Each player sees the questions only they got right.
FAQ
1 What does the name mean?
Rikaido Me comes from the Japanese word 理解度 (rikaido): how well someone understands you. Friends guess your picks, and the score is how close they got.
2 Do my friends need an account?
No. You type a display name to make a quiz, and they type one to play. Use a nickname — names and scores are visible to anyone who has the link.
3 How is the score calculated?
Each guess is checked against the side you picked. One match is one point, with no weighting. The result also shows the best and worst topic and a rank against everyone else who played that link.
4 Will two quizzes have the same questions?
Usually not. Each quiz is a fresh draw from the pack, spread evenly across its topics. Only the longest length uses every question, and even then the order is shuffled.
5 Which pack should I pick?
The main mix if the chat is mixed. Love for a partner, School for a class chat, and Food, Games, Oshi, SNS, or Dark when the group already shares that one thing.
6 Who sees the ranking?
Anyone with the link can play and then see the names and scores on it. There is no private league, so treat the link like a postcard.
7 Is it free?
Yes. Making a quiz and playing one both cost nothing, and there is nothing to install.
