Factory Basics

Algae, Inc. core concepts: algae and storage, conveyor belts, byproducts and energy, the department board, the side board with its science grid, resources and contract cards.

Algae

Algae cubes

All Algae cube algae cubes look alike; where a cube sits says what it is. There are four species:

IconSpeciesMap tank
Red AlgaeRed algaeMacro Algae Tank macro algae tank
Brown AlgaeBrown algaeMacro Algae Tank macro algae tank
SpirulinaSpirulinaMicro Algae Tank micro algae tank
ChlorellaChlorellaMicro Algae Tank micro algae tank

The map has one tank per species, each with a capacity marker (4 at the start, up to 6). The tanks are refilled every weekend.

Algae storage

Algae Storage On the left of your department board are four storage rows, one per species. You start with only one open; the other three are covered by algae storage science tiles. You may only take algae of species whose storage is open, and only as many as it holds.

Remove a storage tile with your scientists to open it — and at once raise that species’ tank capacity on the map by one step (max 6). Some storage tiles have a minimum cost (3+ or 4+ science) whatever zone of the grid you put them in.

Conveyor belts

Cubes move from algae storage → Station 1 → Station 2 → finished good storage in the dispatch area.

BeltMoves when
Main conveyor belt Main (yellow)Its machine is activated (up to capacity), Monday engineer moves, the alternate action, conveyor belt upgrades.
Secondary conveyor belt Secondary (blue)Only when the machine of its zone is activated.
Refining conveyor belt Refining (orange, Biofuel)Only during a refining.

The three machines:

A machine activation runs all belts in its zone; every other way of moving cubes uses the main belts only. Secondary belts may cost you cubes or energy (mandatory) or give you byproduct or energy (optional). Machine rules

Byproducts

The two byproduct tanks

Byproduct Byproduct is the same wooden cube, defined by where it sits: Bio-oil Byproduct bio-oil and Biomass Byproduct biomass, each with its tank on the map.

A department that makes one type can use the other: Machine A turns lost algae into byproduct (burn it for energy or store it for money), and Machines B and C can feed byproduct from the tanks back into your line as new algae.

Energy

Energy Track Your energy marker sits on the shared track, starting in the middle. Gain: move right; spend: move left.

Department board

A department board with its zones numbered

  1. Algae storage — four species, one open at the start.
  2. Machine A — usually loses some algae as byproduct.
  3. Machine B — can add byproduct from other departments.
  4. Machine C — can add more byproduct before goods are finished.
  5. Dispatch area — finished goods ready to export, each with its market value.
  6. Byproduct converter — how many cubes Machine A converts, and what you may do with them.
  7. Facility — your staff; more staff, bigger actions, bonuses and VP.
  8. Player aid — the three phases of a week.

Light-blue framed spots hold your science tiles at the start; dark-blue spots receive engineering tiles later. Each department’s layout is different: The four departments.

Side board

A side board with its sections numbered

  1. Export section — your 10 export disks and 10 milestone markers on top of your 10 export/2x tiles. Moving disks and markers to the map reveals Monday income and unlocks the tiles.
  2. Science grid — starts full of engineering and combo tiles; science tiles are placed here.
  3. Science track — your science points, 0 to 10.
  4. Contracts and exchange — your three contract cards, the exchange rates and the end-of-the-month summary.

Science, engineering and combo tiles

The game is about swapping tiles between your two boards:

TileStarts onMoved byGoes toEffect
Science tile ScienceDepartment boardScientists (2–5 science)Science grid, face downReveals the upgrade under it; covers grid bonuses; scores in your largest group
Engineering tile EngineeringScience gridEngineers (0–3 points)Department board, face upImproves a machine or belt; frees grid space
Combo tile ComboScience gridEngineers, then scientistsBeside your board, flipped; later the grid as a science tileFrees grid space now, scores and covers bonuses later

Some engineering and science tiles come in stacked pairs; place the lower one first.

Resources

The resources are Euro euros, Freelance Engineer freelance engineers, Market Value Token market value tokens and Science (Point) science points. Choice and wild action tokens are not resources.

Exchanging resources

Only while paying a cost, you may exchange any resources and choice action tokens 2 for 1, and 3 for 1 wild action token to use as your action.

Contract cards

Contract cards: front and back

Each department has 9 contract cards. At setup you draw 3 and slide them into your side board so that exactly one of each part shows:

PartShowsUsed
TopA permanent abilityAll game
MiddleA contract exportOnce, as one of your exports
BottomAn end-of-the-month scoringAt the end

Every card is listed in the appendix: contract cards.

Market value and demand

Each finished good storage shows its Market Value market value — fixed, or depending on how many goods you deliver together. Each city’s Demand Value demand token is the market value you need to export there. Export
