Generators are major nodes that generate currency, such as Entropy, Ideas, Fossil or Stardust. They have different variants, each one separated into different trees.
Cost and Production[]
Generators cost a certain amount of currency, each costs 15% more than the previous one of the same kind. This roughly quadruples the cost every 10 levels. The more powerful and efficient the generators are, the more those generators will cost.
The cost of purchasing N generators can be determined by the formula:
where C = cost, N = number of generators, and P = current price of generator. This works for almost all generators, but there are exceptions. For example the L.U.C.A generator in the Life After Apocalypse event.
Below is the list of in-game generators with some of their details. Note that their production per second in the list is calculated without any boosts applied:

It is home to most dwarf planets in the solar system. | 5.06e34 | 1.17e30 | 14 s | - | |||
| 11 | Haumea | The dwarf planet Haumea was discovered in 2004 and named for the Hawaiian goddess of childbirth. It has an unusual oblong shape and is the only trans-Neptunian object with a ring system. | 3.48e36 | 3.03e34 | 3,040 s (50:40) |
- | |||
| 11 | Makemake | Makemake is a cold dwarf planet found in the Kuiper Belt. It is the second brightest trans-Neptunian object after Pluto. It has a red surface and one orbiting moon. | 7.72e38 | 5.63e36 | 3,290 s (54:50) |
- | |||
| 11 | Eris | One of the largest dwarf planets in our solar system and the farthest from the Sun, Eris is named for the Greek goddess of discord and strife. A day on Eris is about the same length as a day on Earth. | 2.43e40 | 4.64e38 | 6,010 s (1:40:10) |
- | |||
| 12 | Heliosphere | The heliosphere is the region in space that surrounds the Sun. It is continuously inflated by solar wind and protects the solar system from cosmic rays. Its outermost region, the heliopause, is the boundary between our solar system and interstellar space. | 2.94e43 | 3.33e40 | 1,420 s (23:40) |
- | |||
| 13 | Sedna | An icy red planetoid far beyond the orbit of Neptune, Sedna takes 11,400 years to orbit the Sun. It is named after the Inuit goddess of the Arctic seas. | 5.67e46 | 3.77e44 | 2,350 s (39:10) |
- | |||
| 14 | Planet X | Scientists observing the outer edge of the solar system have long theorized that there may be a ninth planet past the orbit of Neptune. Its gravitational pull could explain the clustered orbits of many small trans-Neptunian objects. | 1.07e50 | 3.67e47 | 2,870 s (47:50) |
- | |||
| 15 | Hills Cloud | The Hills Cloud is the inner part of the Oort Cloud. While comets with orbits of less than 200 years come from the Kuiper Belt, comets with longer orbits—ranging from 200 to 2,000 years—originate in the Hills Cloud. | 1.42e52 | 3.01e48 | 92 s (1:32) |
- | |||
| 15 | Oort Cloud | The Oort Cloud is a field of small icy celestial bodies thought to exist at the far reaches of the solar system. It surrounds the bubble of the heliosphere, and is the bridge between our solar system and interstellar space. | 2.21e54 | 2.19e51 | 1,910 s (31:50) |
- | |||
| 17 | Alpha Centauri | Alpha Centauri is the closest solar system to our own. 4.37 light years from our Sun, it consists of three stars and at least two exoplanets. | 5e57 | 3.14e55 | 6,500 s (1:48:20) |
- | |||
| Phase 2: Milky Way (July, 2023) | |||||||||
| 18 | Barnard's Star | Just 6 light years from the Sun, Barnard's Star is a red dwarf, small and dim. Yet this ball of hot gas has enough mass to trigger nuclear fusion—hydrogen atoms combining into helium. That puts it in the main sequence, a class of assorted stars that are young and stable. | 5.61e63 | 1.36e60 | 131 s (2:11) |
- | |||
| 18 | Tau Ceti | About 12 light years from Earth, Tau Ceti is a sunlike star of medium size and mass in the main sequence. Like the Sun, it's a solitary yellow dwarf, and it even has at least four earthlike planets in orbit. About one in 10 Milky Way stars are yellow dwarfs. | 4e65 | 6.82e63 | 1,620 s (27:00) |
- | |||
| 18 | Sirius | Sirius is a pair of oddball stars. Sirius A is blue-white—the brightest, most massive, and rarest star type in the main sequence. Sirius B was born a blue star but is now a white dwarf, a compact star that spent its hydrogen fuel and left the main sequence long ago. | 6e67 | 3.71e66 | 4,330 s (1:12:10) |
- | |||
| 19 | Polaris | Like most stars, Polaris spent 90% of its life in the main sequence. It exited that stage when the core's hydrogen ran out. Now, Polaris Aa, the top star in a triple system, is fusing helium atoms in its core. That energy boost swelled the star into a yellow supergiant. | 2e70 | 1.5e69 | 2,100 s (35:00) |
- | |||
| 19 | Rigel | The life of a mega-mass star is short and dazzling. Rigel A is a blue supergiant ruling over three main sequence stars. It's young, just 8 million years old, and white hot. The star burns so brightly that it blinds Earth's telescopes—even from 860 light years away. | 6.64e72 | 3.58e71 | 3,589 s (59:49) |
- | |||
| 19 | Arcturus | Arcturus offers a sneak peek into the Sun's future. Once a young yellow dwarf, it's now a geriatric 7.1-billion-year-old red giant. The star's mass hasn't changed much, but its girth is 25 times bigger. The surface is brighter than the sun, but cooler. | 3.67e74 | 5.19e72 | 1,767 s (29:27) |
- | |||
| 19 | Van Maanen's Star | Van Maanen is a dying white dwarf that's two-thirds the mass of the Sun and just 1% of its size. The helium atmosphere has a puzzling supply of heavy elements-iron, magnesium, and calcium. They might be the dust of a planet crushed by the superdense star's gravity. | 1.23e77 | 6.26e73 | 76 s (1:16) |
- | |||
| 20 | Fomalhaut's Ring | Fomalhaut A, a young blue star, is just starting its planetary family. The telltale sign is a clearly defined ring of rotating matter, part of a dusty disk nicknamed Eye of Sauron. The ring formed as rocks grew massive enough to pull loose debris into tight formation. | 3.89e79 | 1.16e79 | 1,281 s (21:21) |
- | |||
| 20 | WASP-12b | The parent star of WASP-12b is a yellow dwarf, like the Sun, but it is ripping its child to pieces. The planet orbits so closely that powerful tidal forces from the star's gravity warp it into an odd egglike shape called a Roche Lobe. | 8.7e81 | 1.28e78 | 60 s (1:00) |
||||
| 20 | Awohali | Awohali is a Neptune-sized planet that hugs a red dwarf in close orbit. There, ice meets fire. Heat from the star and from strong tidal forces inside Awohali melt and vaporize rock and ice. The debris forms a shiny halo and a long tail behind the planet, like a comet. | 2.75e82 | 2.13e79 | 120 s (2:00) |
||||
| 20 | Kepler-70b | After surviving its star's red giant phase, Kepler-70b emerged as a small, rocky core of its former self—about the size of Earth. Its surface is hotter than our Sun, soft and molten. The planet is slowly evaporating as it orbits a dim, dying parent star every 4.8 hours. | 4.96e84 | 1.55e81 | 2,030 s (33:50) |
||||
| 20 | Janssen | Designated 55 Cancri e, Janssen is a super-Earth that orbits a sunlike far too closely for life to exist. What's intriguing is its extreme density. The planet is twice the size of Earth, but 9 times more massive. That means it's terrestrial, but made of what? | 1.87e85 | 7.99e80 | 48 s | ||||
| 21 | Enaiposha | Enaiposha is a warm super-Earth with hazy skies lit by the rosy glow of a red dwarf. Three times bigger and 8 times more massive than Earth, the planet's density means a chunk of it must be lighter than rock but heavier than gas. Very likely, Enaiposha is a water world. | 2.74e87 | 8.17e83 | 15 s | ||||
| 21 | Kepler-186f | Kepler-186f is almost Earth's twin-just a tad bigger and denser. It orbits at a life-friendly distance, well beyond four scorched siblings that are too close to their star. Its composition and atmosphere are unknown, a data gap for Webb and other telescopes to fill. | 1.17e90 | 1.44e86 | 129 s (2:09) |
||||
| 21 | TRAPPIST-1 System | Seven rocky worlds orbit the solo star TRAPPIST-1, shining like moons in each other's skies. Three planets are in the habitable zone, and all seven could have water. The orbital plane is flat and stable, with circular paths, like Earth`s. But there are perils. | 8.98e92 | 1.77e91 | 4,066 s (1:07:46) |
- | |||
| 22 | Helix Nebula | At the heart of this cloud glows a dead red giant, the immediate afterlife of a medium-mass star like our Sun. After core fusion shut down, the star began shedding gas, forming a planetary nebula. "Planetary" is a misnomer—the nebula is all about that dead red star. | 6.95e94 | 2.87e92 | 760 s (12:40) |
||||
| 22 | Cat's Eye Nebula | Beautiful and complex, all the gas in the Cat's Eye Nebula amounts to only 1% of the Sun's mass. It includes rare ionized nitrogen and double-ionized oxygen (atoms stripped of two electrons). One mystery is why this young planetary nebula is swirling so swiftly. | 3.26e96 | 9.8e92 | 20 s | ||||
| 22 | Hourglass Nebula | The Hourglass Nebula defies explanation. A small hourglass nests in a large one, but the dead star isn't at the center of either one. Two inner rings circle the eye at right angles. But why? If there's a binary star, it wouldn't account for this one-of-a-kind shape. | 8.3e98 | 1.3e95 | 80 s (1:20) |
||||
| 23 | Crab Nebula | In the constellation Taurus, the remnant of a supernova explosion marks the death of a high-mass star. The beautiful Crab Nebula is 10 light years across and still growing. Working backward from its rate of expansion, the year of the star's death was 1054. | 6.52e101 | 5.5e99 | 1,001 s (16:41) |
||||
| 23 | Crab Pulsar | Near the heart of the Crab Nebula is the core of its exploded star, reborn. The Crab Pulsar, a neutron star, packs 1.5 solar masses into a ball as wide as a city, rotating 30 times per second. Its tiny size and immense density keep this energetic orb from flying apart. | 7.18e103 | 2.78e99 | 20 s | - | |||
| 23 | Carina Nebula | Carina Nebula isn't a supernova remnant. It's a supernova factory, aglow and abuzz with young, massively energetic stars and towering pillars of ionized gas and dust. This complex cloud is bigger than most and 15 times brighter than the famous Orion Nebula. | 7.5e105 | 1.08e103 | 230 s (3:50) |
||||
| 23 | Cygnus X-1 | In 1971, the Uhuru satellite tracked X-ray bursts that were strong, uneven, and very short. Their brevity meant the unseen source was smaller than Earth's moon. Their pattern ruled out a pulsar. Cygnus X-1 became the first verified black hole. It's paired with a star. | 6.2e108 | 6.5e105 | 2,042 s (34:02) |
- | |||
| 24 | Eagle Nebula | It’s not the remnant dust of a faded or exploded star. Instead, the much larger Eagle Nebula formed from cold interstellar gas that condensed into O stars—the hot, blue kind. Thousands of them strip the ions from nearby gas molecules, setting the clouds aglow. | 7.55e111 | 6e109 | 7,000 s (1:56:40) |
||||
| 24 | Pillars of Creation | Rocketed to fame by a Hubble Space Telescope image, these twisting columns of gas and dust rise 4 to 5 light years inside the Eagle Nebula. Their theatrical glow is courtesy of a nearby star cluster, whose UV energy is gradually eroding the tops of the pillars. | 1e114 | 4e109 | 300 s (5:00) |
||||
| 24 | Orion Nebula | Hanging below Orion’s blue-starred belt, three dim stars make up his sword, which carries the sheen of a nebula. Ancient Maya called this shiny cloud the “cosmic fire of creation.” And they were right: the Orion Nebula is the nearest stellar nursery to Earth. | 3e115 | 1.2e113 | 1,344 s (22:24) |
||||
| 24 | Horsehead Nebula | A small, dark nebula, like the Horsehead, is a nursery bustling with star births. Here’s why: the cloud is super dense with grains that block the light behind it, and that dense matter can easily clump into protostars that form stars. | 5.4e117 | 6.8e114 | 1,500 s (25:00) |
||||
| 25 | Orion Spur | The Milky Way stretches horizon to horizon across our night sky, a bright smear streaked with a Dark Rift. Our view is from a spur of stars within the galaxy. We're halfway between the core and the rim—each about 26,000 light years away. | 8e121 | 3.1e116 | 350 s (5:50) |
- | |||
| 25 | Perseus Arm | Named for the constellation it appears in from Earth, Perseus is one of two major arms that spiral out from the galactic core. This may surprise you: spiral arms and stars don’t travel in sync. Stars speed into an arm, get jammed up there for a time, and then move out. | 6.4e122 | 1.07e118 | 240 s (4:00) |
- | |||
| 25 | Omega Centauri | A dense ball of 10.5 million stars, Omega Centauri is the biggest and brightest of about 200 globular clusters in the galaxy. The average distance between its stars is just one tenth of a light year—about as close as the inner Oort Cloud is to the Sun. | 1.71e123 | 1.04e120 | 8,600 s (2:23:20) |
||||
| 25 | Galactic Bulge | The central bulge is a sphere containing the galactic bar. Most stars are in the disk, but the bulge is so dense with them that their planets could never experience night. With density comes chaos, and these mostly old stars zip around in unpredictable orbits. | 2.6e124 | 3e121 | 3,000 s (50:00) |
- | |||
| 26 | Galactic Nucleus | Sagittarius A, the nucleus of the bulge, churns with jam-packed clusters of old red giants, dotted with young supergiant and Wolf-Rayet stars. Those new stars are mystifying. Savage tidal forces, caused by an overwhelming gravitational pull, should prevent their birth. | 4e126 | 8e121 | 800 s (13:20) |
- | |||
| 26 | Sagittarius A* | The supermassive black hole in the pit of the Milky Way is real and has a name: Sagittarius A star (Sgr A* for short). With a mass of 4.3 million Suns, it could fit inside Mercury’s orbit. No light escapes its grip, but images show EM emissions from matter orbiting it. | 2.66e128 | 1.2e122 | 12 s | ||||
| 27 | Milky Way Galaxy | With 400 billion stars, our galaxy is a bigwig in the Local Group of 50 or so galaxies. It began 13 billion years ago as blobs of gas and dust that ignited into star clusters, pulling in matter. The mass contracted, rotated around a nucleus, and flattened into a disk. | 1e132 | 5.29e129 | 13,610 s (3:46:50) |
||||
| 27 | Sagittarius Dwarf Galaxy | This elliptical galaxy is so close to the Milky Way that some of its one billion stars overlap with ours. Elliptical galaxies vary dramatically in size, have a uniform oval shape with no clear features, and are past their star-making prime. | 6.52e134 | 5e129 | 4,500 s (1:15:00) |
||||
| 27 | Large Magellanic Cloud | The Milky Way siphons gas from this tiny galaxy—critical fuel for star birth—but the gravitational tug-of-war isn’t one-sided. Both Magellanic Clouds pass through the dark matter halo, which amplifies their gravity. The force vibrates and warps our entire galactic disk. | 1.58e136 | 7e130 | 7,000 s (1:56:40) |
||||
| 27 | Triangulum Galaxy | The third-most massive galaxy in the Local Group has lived a peaceful life so far. The spiral arms are loose and symmetrical, and its dust is evenly spread. But it is being gravitationally drawn to the far larger Andromeda Galaxy—which portends a violent future. | 2.72e137 | 5e133 | 10,000 s (2:46:40) |
||||
| 27 | Andromeda Galaxy | With 1 trillion stars and 30 satellite galaxies under her gravitational spell, Andromeda is the galactic queen of the Local Group. As with stars, mass is destiny, the prime driver of a galaxy’s fate. What does that fact mean for number two, the Milky Way? | 2.54e139 | 1.1e136 | 16,000 s (4:26:40) |
||||
| 28 | Virgo Supercluster | With 100 groups and clusters of galaxies—our Local Group among them—this supercluster holds 10 quintillion solar masses of matter. But some of its galactic packs are not moving toward the center. Those strays muddy the boundaries and definition of “supercluster". | 1.1e141 | 1.48e137 | 10,000 s (2:46:40) |
||||
| 28 | Centaurus A Group | Between our Local Group and the supercluster center lies the Centaurus A Group. Its biggest galaxy is an elliptical giant blasting out radio waves, the sign of a recent meal. Just 500 million years ago, Centaurus A absorbed a spiral galaxy that it’s still digesting. | 1.4e142 | 1.1e137 | 440 s (7:20) |
||||
| 28 | Virgo Cluster | The queen of the Virgo Supercluster is the Virgo Cluster. It's similar in size to the Local Group but far denser, with 2,000 galaxies and a rash of rogue stars and globular clusters. Three subclumps will one day merge into an even more powerful center of attraction. | 5.3e143 | 2.2e140 | 1,500 s (25:00) |
||||
| 28 | Messier 87 Galaxy | At the heart of the Virgo Cluster, the galactic boss of the supercluster weighs 2.4 trillion Suns. From 50 million light years away, we can see M87 through small telescopes. Old and elliptical, it grew into a behemoth by snacking on lots of smaller galaxies. | 2.4e145 | 9.6e140 | 87 s (1:27) |
||||
| 28 | Quasar 3C 273 | Quasi-stellar radio sources, or quasars, are AGNs so extreme—with black holes so voracious—that they shine as bright or brighter than their galaxy. The luminosity of this nearest quasar to Earth is 25 times that of the Sun. | 2.4e148 | 1.29e143 | 273 s (4:33) |
