60 Worldbuilding Exercises Based on Rainy Days

Trezonic · October 13, 2026

Use this collection to develop a fictional setting whose rules create believable choices and consequences. The theme is rainy days: a day whose small adjustments make familiar routines feel different. You will find a practical method, 60 original exercise variations, a worked planning example and a checklist for choosing a useful next step. Start with one prompt rather than trying to complete the whole collection at once.

Practice collection: the scenarios and examples are invented. Adapt them to your own work; a real review or factual claim requires your own experience and evidence.

A practical method for rainy days

Worldbuilding is most useful when a rule changes what a character can do. Before designing a complete history, choose a small part of daily life: how people obtain a resource, enter a place, share an obligation or recognize a promise. Ask who benefits from the current arrangement and who has to work around it.

A setting can be speculative, realistic or somewhere between them. In every case, separate what is normal in that world from what is unusual in the scene. If everything is surprising, a reader has no stable point from which to understand the change. Show one ordinary routine clearly, then introduce the exception that creates the story's problem.

Rules need limits. A convenient system that always provides the required answer removes decisions from the characters. Give the system a cost, delay, constraint or disputed interpretation. Let different people encounter the same rule from different positions. That difference makes the setting feel inhabited rather than built solely for the protagonist.

Use a scene to test the world. A person trying to borrow an object or correct a misunderstanding can reveal more than a page of general background. Keep a separate note of the rules already demonstrated in the draft. When a new rule would solve a problem too easily, decide whether it needs to be introduced earlier, limited more carefully or removed. The goal is a setting readers can reason about as the story unfolds.

Choose a daily routine → State the relevant rule → Identify its limit → Show two perspectives → Test the consequence in a scene

Choose the version that fits your session

For a solo session, choose one prompt and keep a written record of the result. For a pair or small group, explain the task before reading the first question and decide how turns will work. For a longer project, save two or three prompts that address different parts of the task. The collection offers options; completing more exercises is not automatically a better result.

60 exercise variations: Rainy Days

The six rounds change the perspective or constraint while returning to the theme. Read a complete prompt and its follow-up before choosing. You can adapt an object, move the setting or replace a complication when that makes the exercise more useful. Keep the function of the question rather than treating the wording as a rule.

Round 1: Start with one concrete detail

  1. Invent a rule governing the use of a wet umbrella at a sheltered meeting place. Give the rule a reasonable purpose, then show an ordinary situation in which following it creates a difficulty.

    For this version, keep the scene in one location and let a warm drink influence a decision before the ending.

  2. In a fictional version of a sheltered meeting place, a soaked notebook happens for a different reason than it would in everyday life. Define that reason and one limit on how people can respond.

    For this version, keep the scene in one location and let a window pane influence a decision before the ending.

  3. Let the sound of shoes on a dry floor signal a change that locals understand but a newcomer does not. Explain the meaning through a practical response rather than a lecture about the world.

    For this version, keep the scene in one location and let a coat hook influence a decision before the ending.

  4. Imagine that possession of a window pane grants a modest privilege. Decide how the object is obtained, who verifies it and what happens when the claim is disputed.

A worked planning example

Imagine a practice session centered on a wet umbrella at a sheltered meeting place. The complication is a cancelled outdoor plan. This is an invented setup, so there is no claim that the event happened or that a particular real location has these conditions. The purpose is to make a fictional setting whose rules create believable choices and consequences. Start by writing one sentence about that purpose and one sentence about the concrete detail you will use.

In the first pass, describe what is available in the scene or task. A detail such as rain against a window can provide context, but it should not replace the practical decision. Record the object, the setting and the immediate difficulty separately. That small separation makes it easier to see which parts of the setup you can change without losing the point of the exercise.

Next, apply the first step: choose a daily routine. Keep the attempt small enough to finish. If the exercise involves a written scene, draft the action before adding all the background. If it involves a conversation, ask the concrete question and let the answer determine the follow-up. If it involves a plan or review, write down the relevant observation and identify what still needs confirmation. Use the instruction that matches the selected exercise rather than treating every example as the same kind of task.

Now change one condition. Replace the starting object with a warm drink, shorten the available time or move the attention to another participant. Keep the rest of the setup steady long enough to compare the results. This is a comparison of practice attempts, not evidence that one response always works better for every person or place. Notice which change makes the intended outcome clearer.

Practice worksheet for Rainy Days: setting, starting details, complication and goal
Use the worksheet to organize an invented example or your own accurately described experience.

Check your result before sharing it

  • The result supports the purpose: a fictional setting whose rules create believable choices and consequences.
  • The starting situation is clear without needing a long explanation.
  • Each important detail has a practical job in the exercise.
  • An invented example is identified as invented.
  • A real experience is described within the limits of what you observed.
  • A factual detail that may change is checked with an appropriate primary source.
  • A participant can choose how much to contribute and can pass.
  • Private information and another person's image are handled with appropriate permission.
  • Commercial recommendations, affiliate links or sponsorships are clearly disclosed when present.
  • The next useful action is small enough to complete with the time and resources you have.

Common mistakes to avoid

A broad label can feel like a complete answer when it only names the subject. Replace a general claim with one observable detail, one choice or one example. Avoid adding an elaborate explanation before the reader or participant knows the practical situation. When a question does not fit, adapt it openly rather than forcing an irrelevant answer. Repeating the same effect in different words can make a piece longer without making it more useful.

A second common mistake is treating a practice result as a verified account. A fictional scene does not establish what a real place is like, and a game answer does not establish a permanent fact about a person. Keep those boundaries clear when you move from a private exercise to a public post, review or conversation. If the result depends on something you have not checked, name the missing information and decide how to obtain it.

Common questions

Do I need to complete all 60 prompts?

No. Choose one that fits the task you want to work on. A completed, specific attempt usually gives you more to revise or discuss than many unfinished starts. The remaining prompts are options you can return to when you want a different focus.

Can I change the setting or objects?

Yes. Replace a detail when the new version makes the exercise useful for your project or group. Preserve the practical relationship that creates the question: a choice, a limitation, a difference in attention or a consequence worth following.

Are these examples factual accounts?

No. The sample situations are invented for practice. A real review or practical claim needs your own accurately described experience and suitable evidence. The collection does not supply live prices, provider rules, opening times or a first-hand test of a product.

How can I use a prompt with a group?

Explain the format, invite a brief answer and offer a pass option. You can use an imagined response. Choose one question at a time and let the next contribution follow what someone actually says instead of demanding a more personal disclosure.

What if a prompt does not fit the book or project?

Choose another prompt or adapt the function to a relevant detail. A reading exercise should stay grounded in the book you actually read. A creative task can use a new fictional detail. Neither requires you to invent a factual claim to make the question fit.

What is a useful next step after the exercise?

Keep the part that made the task clearer. You might revise one paragraph, record one checked fact, select a stronger frame or ask a more specific follow-up. Write down the next action and complete it before expanding the plan into a much larger project.

Keep a useful result

For rainy days, begin with a wet umbrella and the task that makes it relevant. Choose one exercise, complete a small attempt and review whether the result supports a fictional setting whose rules create believable choices and consequences. Save the question that helped, adapt the part that did not fit and keep the next step concrete. You can return to a different round when you need a new perspective.
