GUIDES & INFORMATION

How to play & examples

This guide is available in Japanese and English.

Pick a tool to spark a conversation with friends or a little adventure outside. All three tools work without signup.

01 / SECRET INVITATION

First Come, Secret Shared

Set a participant target, then share text or one photo with the first participants for 24 hours after the target is reached.

  1. Separate your teaser from your secret. The teaser is visible to people with the link. The secret text and photo stay hidden until the target is reached. Include text, a photo, or both.
  2. Choose a target and create a link. The range is 1–100,000. For a first try, choose a small group you can actually invite.
  3. Share the link. Browsers secure a place when their join request completes. The creator also uses a place if they open the participation page and join.
  4. Enjoy the reveal together. Only browsers with a place can read the secret after the target is reached. New participants cannot join after the reveal.

If the target is not reached, viewing ends seven days after creation. If it is reached, viewing ends 24 hours after the reveal. Expired content is scheduled for deletion. Creators can withdraw a post earlier from “My secrets” in the same browser.

Clearing cookies can remove participation and management access. Screenshots, copies and reposts by viewers cannot be prevented. Do not post personal information or photos of others without permission.

02 / LITTLE ADVENTURE

Outing Challenge Maker

Draw restrictions for shopping, food and posting. Each rule limits what you may choose or include. Destination and budget are up to you.

  1. Draw three rules: 40 shopping rules, 40 food rules and 40 posting rules make 64,000 combinations. Each category has just one restriction.
  2. Redraw any category independently. Changing shopping does not change food.
  3. Try the rules and report on your own social media. Purchases and meals are optional.
  4. Save or share a PNG challenge card in feed format (1080×1350) or story format (1080×1920). Nothing is posted automatically.

Posting restrictions apply to your own report, not to the challenge card or link description. Drinks and dietary needs are exempt. Redraw any unsuitable rule.

Shared links preserve the same rules across languages. Older v=2 links retain the original activity, photo and post challenges. With 64,000 combinations, duplicates between people are still possible.

For Instagram, attach the saved image and paste your text yourself. No photos or location are uploaded. Respect privacy and photography rules.

03 / TRUTH OR LIE

Liar King

Find the one lie among three statements, or create a quiz for your friends.

  1. Enter a creator nickname and a question. Add three options and mark exactly one as false. Do not include private information or copied material without permission.
  2. Add an explanation. Explain why the answer is false and include a reliable source URL where possible.
  3. Share a challenge. Send the quiz link on social media or by DM. Answering reveals the solution. Creators cannot answer their own quiz.
  4. See the results. Quizzes show attempts, accuracy and how many people were fooled. Creator rankings require at least 10 answers and adjust rates for small samples.

Manage your quizzes through “My posts”. Quizzes cannot be edited after someone answers, but can be deleted. The secret tool’s 24-hour/seven-day expiry does not apply to quizzes.

Clearing cookies or changing browsers loses access to posts and answer records. The interface supports 12 languages; user-written questions and explanations are not translated. Use “Report post” for problematic quizzes.
