How it works
From a data point to a daily round
Start with one sourced target and one scoring rule; add a second category only after the round works.
- Step 1
Choose one target
Pick one kind of estimate—height, runtime, population or mass—and keep the first round focused.
- Step 2
Verify the reference
Record the data source, date, unit and definition beside each answer.
- Step 3
Set input and scoring
Describe accepted answers, aliases, rounding, ties and the feedback after each guess.
- Step 4
Define the daily rule
Choose a timezone, reset point and whether practice rounds affect the daily result.
- Step 5
Test the full round
Submit a prompt through the available account flow, then check valid, invalid, repeated and boundary guesses before sharing.

Mountain Height
Estimate a summit from a dated elevation source and a stated unit. AI concept illustration, not gameplay.
Prompt
Build an original daily mountain-elevation guessing game with its own name and visual identity. Use a small, licensed or public reference list with source, year and elevation unit stored beside each answer. Ask players to name a mountain or enter an estimate; normalize spelling and units, reject unknown entries without counting a guess, then reveal the sourced elevation and absolute difference. Define how ties work, keep the daily target stable for the chosen timezone, and provide a replayable practice round. Use keyboard-accessible input, visible validation and a concise results screen. Do not copy Plain’s name, logo, art or answer set; this is an independent prototype. Test valid, duplicate, unknown and boundary inputs.
- Store the elevation source and reference year with each answer.
- Choose one unit and explain any conversion.
- Reveal the answer and the difference after the round.

| Data | Choose a source, year, unit and boundary for each target. | Check the official source for its current content and terms. |
| Scoring | Set your own estimate-distance and tie rules. | Follow the reference game’s own scoring behavior. |
| Artwork | Create original names, copy and visuals. | Use the game only as a genre reference; do not reuse its assets. |
| Review | Test invalid guesses, aliases, dates and result feedback. | Use the original game’s official experience for its daily challenge. |

FAQ
Questions about daily estimation games
What is a Plain-inspired daily estimation game maker?
This page helps you describe an original estimation-game prototype with a target, answer set and scoring rule. It is an independent creation page, not the official Plain game and not affiliated with its publisher.
Can this page recreate the official Plain game?
No. Use Plain only as a broad genre reference. Give your prototype an original name, artwork, copy and rules; do not copy its logo, interface or proprietary answer set.
What should I decide before choosing the answer data?
Pick a source you can use, record its date and define what each number measures. For population, distinguish city boundaries; for runtimes, identify the edition; for animal mass, state how the reference value was chosen.
How should an estimation score work?
Choose an explicit rule such as absolute difference or percentage error, then define rounding, ties and when the answer is revealed. Show enough information for a player to understand the score.
Can players enter different units?
They can if your brief requests conversion. State the accepted units, conversion precision and how the game displays the normalized value; test each unit before sharing the prototype.
How do I handle a guess that is not in the answer set?
Specify whether to reject it, offer a suggestion or treat it as a new answer. Make the behavior visible and do not count an invalid entry unless that is an intentional rule.
How should a daily reset be defined?
Choose the timezone and the moment a new challenge begins. Test around midnight and daylight-saving changes where relevant; do not assume a reset works until you verify it.
Can I include a practice round?
Yes. Describe whether practice uses a separate question pool and confirm that it does not overwrite the daily result unless that is part of your design.
What data sources should I use?
Use sources you are allowed to reproduce, keep a citation and date beside each value, and review the definition. Do not present an unsourced sample number as a current fact.
How can I make the input accessible?
Ask for a labeled input, keyboard operation, readable validation and feedback that does not rely only on color. Then test the actual generated flow with keyboard and screen-size changes.
What should I test in the first version?
Try correct, close, far, repeated, malformed and out-of-range guesses. Check the reveal, score, reset and results for each case.
Can I use Plain’s logo or answer data?
This page does not grant rights to Plain’s name, logo, interface or data. Use assets and data you own or are licensed to use, and create an independent visual identity.
Is a generated prototype ready to publish?
Treat the first result as a draft. Verify the rules, sources, accessibility, rights and behavior in the target environment before sharing or releasing it.
What happens when I submit a prompt?
The page uses the current SEELE AI creation flow. Sign-in, available credits, generation options and export choices depend on the account and workspace shown at submission time.
Start with one well-sourced question
Describe the target, source and scoring rule, then test the first round before adding more categories.
