Weather Machine

Weather Machine at a glance: what are you trying to achieve?

Weather Machine is a competitive strategy game about scientists working for Professor Lativ. His invention is causing extreme weather, and each player is trying to gain scientific recognition by researching the problem, publishing papers and building better machines. You score Climate Points (CP) through actions and endgame objectives. Developing your laboratory matters because nearly every ambitious project needs a chain of different resources and actions.

Players move a scientist among four action areas: Supply, Government, Lativ’s Lab and Research & Development (R&D). Your personal workshop holds bots, chemicals and machine parts, while voucher tracks determine which location actions you can afford. Unlike a simple worker-placement game, collecting one resource is rarely the whole plan: a productive visit should set up the next scientific action or scoring opportunity.

Edition and players: the standard game is for 2–4 players, ages 14+, with a publisher estimate of 60–150 minutes. An official solo ruleset exists, but the physical solo components and rules are sold through the Weather Machine Upgrade Pack unless your copy already includes that material. Do not assume the standard retail box is solo-ready.

The four main locations and what each one does

This is a decision aid rather than a full action reference. The official rulebook includes voucher costs, exact placement restrictions and benefits for every location. For the action sequence, see how to play Weather Machine.

Research, publication and prototype: three different milestones

Research develops your work in a particular weather field. Progress helps you participate in later projects, but research by itself is not the same as a completed paper or prototype. Publication at Lativ’s Lab can turn your collected research into recognition, while adding citation opportunities that can matter to later players. Breakthrough work in R&D uses machines and parts to address an Extreme Weather tile and claim an award.

Think backward from the result you want. If you hope to publish, check whether you can obtain the needed research and the appropriate Lab opportunity. If you hope to build a prototype, identify the required machine-part colors, your bots in the R&D branch and the space available to arrange materials in your workshop. A turn spent advancing the wrong weather type may be a perfectly legal move but an inefficient contribution to your chosen project.

There are five weather categories—rain, wind, sun, fog and snow—with corresponding chemicals. Concentrating on one or two compatible projects can make your materials and research reinforce each other, though opponents may create reasons to change direction. The separate strategy article explores research sequencing in more detail.

Practical example: a workshop that looks full of progress

Imagine your scientist has a research opportunity in mind and you already own the chemical you need, but your workshop has no legal space for the next bot or machine part. Buying more materials now will not necessarily move your project forward: workshop tiles have particular storage restrictions, and you cannot simply throw away a resource to make room whenever you like.

A more productive Supply visit may be to extend the workshop first, then use the new capacity to prepare the next action. Conversely, if you already have adequate storage but no appropriate vouchers, an expansion can be a costly detour. The real bottleneck is the missing link in the action chain, not whichever resource appears easiest to collect.

Before visiting a location, check: (1) the required voucher, (2) the chemical or part colors, (3) the bot or research placement, and (4) legal workshop space. This is an illustrative planning checklist; the precise restrictions and exceptions are in the rulebook.

Why experiment timing can change the value of a bot

Each round includes player turns, an attempt to run the Weather Machine experiment and an end-of-round phase. The experiment concerns the active weather branch indicated by Lativ’s assistant. A bot committed to a branch that will not complete an experiment soon may be less immediately useful than one placed where the required experiment and positions are likely to come together.

This creates a shared-timing decision: contributing to an experiment can help your scientific progress, but completing the branch may also benefit rivals who placed their own bots there. If you are deciding between a reliable short-term experiment and a speculative future one, compare the reward, the location’s current completion state and what other players could do before the machine runs.

The machine’s result is not automatic merely because someone placed a bot. The active branch must satisfy the experiment conditions. Use the rules overview for the exact experiment procedure rather than assuming every new bot immediately produces points.

Funding, awards and deciding when to stop preparing

Government, Lab and R&D funding tracks are not just bookkeeping: their positions contribute to final Climate Points. Awards can be placed in a player’s office for benefits, and the Nobel Prize is an additional five points at final scoring. The exact award and goal interactions belong to the Weather Machine scoring and awards guide.

Four separate events can trigger the endgame, including a player taking the Nobel Prize and the government or research sections reaching completion. After a trigger, play continues through the prescribed final round. A late workshop expansion that would have been useful several rounds earlier may no longer return enough value to justify its action or vouchers.

Editorial decision rule: early investments should improve several later turns, while late actions should make specific Climate Points or a concrete goal more likely. Count your remaining usable rounds, not just the number of unfilled spaces on your laboratory board.

Who should play Weather Machine, and what should you buy?

Best suited to: players who enjoy tightly linked economic decisions, competition for action spaces, long planning chains and managing constrained storage. It is a challenging game even for people familiar with heavier worker-placement titles. A first play may exceed the publisher’s typical time estimate while everyone learns the location and experiment rules.

Less suitable for: groups wanting short turns, low rules overhead or a game where individual resource collection produces immediate rewards. The strongest thematic moments—research becoming papers, experiments and breakthroughs—often require preparing several steps in advance.

Before buying for solo play: confirm whether the copy is the standard base game or includes the Upgrade Pack. Eagle-Gryphon lists the base box as 2–4 players; the Upgrade Pack adds the components and rules needed for the separate solo system. Other optional accessories, such as metal machine parts, are cosmetic and are not the same as the solo upgrade.

Related titles: On Mars explores technological planning and worker-placement interactions, while Kanban EV emphasizes production and resource coordination. These are useful comparisons for complexity and planning style, not interchangeable rulesets.

Frequently asked questions about Weather Machine

Can Weather Machine be played solo using only the standard box?

Do not assume so. The published standard base game is for 2–4 players. Official solo rules are available, but the solo material is supplied by the separately listed Upgrade Pack or bundles that include it.

Do you score by finishing weather experiments only?

No. Experiments support broader scientific development, while publications, breakthroughs, funding tracks, goals and Nobel recognition also affect scoring. Use the chosen rules and scoring reference for exact Climate Point calculations.

Does every research action immediately let me publish a paper?

No. Publishing is a separate action with its own requirements. Check the research you have collected, the appropriate Lab action and any required resources before planning a paper.

Why is my workshop size important?

It limits which bots, chemicals and machine parts you can legally store or arrange. Without the right space, you may be unable to obtain a resource or assemble the prototype you planned.

Is it the same game as Inventions: Evolution of Ideas?

No. Both were designed by Vital Lacerda, but Weather Machine focuses on experiments, climate research and prototype development. Inventions: Evolution of Ideas has a different action system and subject.
