Claim a cow and raise it: milk, battle, breed, and hold the ranch together with your planet guild.
Interstellar Rangeland is the first game in CowGalaxy. Connect your wallet, claim a cow and raise it: cows go to the Dairy Farm to produce milk and mine IRT, bulls go to the Arena to fight card battles for IRG and IRT. Breed, star up, research tech, join a planet guild, fight the weekly Guild War and share the tax rewards. Cows, planets, items and skins are all on-chain assets that you own.
The story: a herd divided
Cow civilization began in Taurus. When the first ships left the home world, the herd split over one question: what is a planet for? Neither side was wrong, so neither side won.
Interstellar Rangeland tells the Empire half: ranches, taxes and the weekly Guild War. The Alliance half is our second game, Interstellar Trek.
Get started in four steps
Connect and claim the starter pack — Sign in with a signature, no gas. Claim the starter pack under "Claim Beta Assets" on this site (once per wallet): a Homeland Planet card, a Genesis cow, an adult bull and cow, a calf, a cow blind box, plus forage, growth packs and test tokens.
Bind a planet, fill the cowshed — Bind a planet in game, or found your own guild with the Homeland card. Put cows in the cowshed and feed them; a calf grows up at 30,000 growth points, in as little as 2 days.
Cows milk, bulls fight — Stake adult cows in the Dairy Farm to keep producing milk and mining IRT; send bulls into the Arena to win IRG and IRT in card battles.
Breed, star up, Guild War — Breeding opens a blind box to grow your herd; starring up makes a cow stronger and resets its lifespan. Research tech, expand the cowshed, and fight the Guild War every week for tax rewards.
What's on the ranch
Cowshed — Home for your cows. Feed forage, use growth and stamina packs, drink life potions; capacity grows with expansions and ranch level.
Dairy Farm — Where cows work. Stake them to produce milk and earn IRT by hash power; badges installed on the farm raise that power.
Arena — The bulls' stage. Turn-based card battles, chests for PVE wins, and ranked matches for seasonal rewards.
Breeding Institute — Every breeding gives a cow blind box: 90% calf, 9.99% fragments, 0.01% Genesis cow. All odds are public.
Research Academy — Climb the tech tree to boost milk and battle multipliers. A higher ranch level (Lv1 to 6) unlocks more tech.
Guild Hall — A planet is a guild. The leader manages members and Federation planets, members share rewards by contribution, and everyone marches into the Guild War each week.
4. How the three games play
All three games use the same wallet login, are free throughout the open beta and run on the Sepolia testnet.
4.1 Interstellar Rangeland
Play at ranch.cowgalaxy.com · Status [Live] open beta · What you do Produce: raise, milk, fight, guild battles
Seven steps to start
- Connect wallet → sign (no gas)
- On the portal, "Claim Beta Assets" → Starter Pack (once per wallet, delivered in three transactions): Home planet card ×1, Genesis cattle ×1, adult bull and cow ×1 each, calf ×1, cattle mystery box ×1, hay ×10 per tier, EXP cards / STR batteries ×3 per tier, HP potions ×1 per tier, TIRT 2,000, TIRG 20,000
- Enter the game and bind a planet (or found your own guild with the Home card)
- Put cattle in the CowShed and feed hay; a calf matures at 30,000 growth, two days at the fastest
- Cows → stake in the Milk Factory to mine IRT; bulls → card battles in the Arena for IRG / IRT
- Breed for mystery boxes, star up, research the tech tree, expand slots
- Weekly Guild Battle, claim tax benefits; swap cattle on the NFT marketplace
Every 24 hours you can also claim the Daily Pack (hay ×10 per tier, STR batteries ×2 per tier, TIRG 2,000) — consumables only, no NFTs or TIRT; requires "entered the game + completed at least one quest".
The life of a cow
| Genesis cattle | Normal cattle | |
|---|---|---|
| Lifespan | Eternal | 35 days × Life ÷ 10000 ≈ 14–28 days, burned on expiry |
| Effective stats | 100% | By star: 0★ 25% / 1★ 40% / 2★ 60% / 3★ 80% |
| Breeding | 5 times + Breed Cards | Up to 5 times |
| Trading | Free transfer and trade | Only calves can be listed; non-transferable once adult |
| Life extension | Not needed | HP potions up to +10 days total; star-up resets lifespan |
Normal cattle die — that is not a bug, it is the largest sink in the economy: restocking requires breeding, and breeding burns IRT + IRG.
Ranch Milk, Arena, Breeding, Raising, Research, Guild, Quests and Trading are the first 8 Play XP dimensions (see section 5.3).
4.2 Interstellar Trek
Play at trek.cowgalaxy.com · Status [Live] open beta · What you do Conquer: push the star map, clear outposts, light up constellations
Log in to trek.cowgalaxy.com with the same wallet you use on the ranch; no new cows needed. Any living adult cow on-chain can fight, with the attack, defense and HP it has on the ranch.
- Pick an outpost: the star map is one draggable, zoomable galaxy map — Taurus → Aries → Scorpius → Orion → Draco, 39 outposts across 5 constellations, unlocked one by one along the route (at least 1 star on the previous one)
- Launch: each sortie costs fuel (12 – 28 per constellation, double for bosses); fuel regenerates 1 point every 14.4 minutes (about 100 / day) and can be bought with IRG (50 fuel = 1,000 IRG, up to 1,000 per day). Fuel is not refunded on a loss
- Fight: the same turn-based card combat as the Arena, with a squad of 1 – 3 cows under your control, each with its own spirit and hand; alien monsters bring 15 exclusive skill cards
- Three stars: win ★, win within the turn limit ★ (6 normal / 9 boss), no cow lost ★; more stars raise the ore and IRG drop cap (×1.6 at 3 stars)
- Loot: every win drops ore and IRG, with chances of sector fragments, ship parts and blueprints; fragments arrive instantly, the rest is claimed from the Reward Center with one on-chain transaction
- Light up a constellation: beat its boss with at least 1 star and collect its fragments (20 / 18 / 16 / 14 / 12) to light it up and open the next one
- Upgrade the flagship: Lv2 = 10 parts + 5,000 IRG, Lv3 = 30 parts + 20,000 IRG; squad size 1 → 2 → 3, fuel cap 100 → 130 → 160
- Summon the AI: in the portal profile page "Agent Authorization", bind your Telegram and create an agent key that can only fight; then open the official bot CowGalaxy Play (@CowGalaxyPlayBot), pick an outpost and a squad, and the AI plays each turn for you, streaming the battle as images and sending a report with drops at the end. Fuel cost, stars and drops are exactly the same as fighting yourself; the agent cannot claim rewards, handle mail, upgrade the flagship or send any on-chain transaction. Keys can carry a daily run limit, can be revoked at any time, and can also be given to your own third-party agent
The avatar at the top left opens your Trek Profile (flagship and modules, total-star ranking, sorties / wins / bosses and lifetime drops); the envelope in the HUD is your mailbox — fuel and fragments from operations mail land directly, while ore / parts / blueprints / IRG go to the Reward Center for a single claim. Trek ore, parts and blueprints are ERC-1155 items on Cattle1155 (ids 110–134) that can be transferred, traded or used now in Interstellar Sandbox. Sector fragments are tracked in game. Trek battle wins and first outpost clears count toward the Expedition dimension of play XP (see section 5.3); wins fought by the AI agent count the same way.
4.3 Interstellar Sandbox
Play at sandbox.cowgalaxy.com · Status [Live] Sepolia public beta (S1–S4 complete, S5 in operation) · What you do Build: choose land, construct, assign cattle, refine, craft, defend
Enter sandbox.cowgalaxy.com with the same wallet. It is a standalone game with two kinds of land:
- Guild planet land: Home and Federation planets have a public Starport, Barn and Defense Tower, plus one 12×12 personal plot per member. The "Planet" button opens the planet map: the central 3×3 is the public zone, every plot occupies one cell, and you can drag, zoom, jump to coordinates and visit other members' plots (read-only). Public buildings are upgraded by member donations; leaving the planet freezes your plot (it thaws automatically when you rejoin the same planet; after 30 days frozen it is soft-recycled, buildings kept); Frontier planets are not open for construction in phase one
- Coordinate NFT land: lighting a Trek constellation lets you mint one transferable coordinate for that constellation and opens a private 12×12 plot — one per constellation per address, up to five. Coordinate land can be moved to any empty cell within ±100 on the planet map (free and without cooldown for now; the reserved 100 IRT move fee is not yet enabled). Taurus gives +20% lumber, Aries +20% refining speed, Scorpius +10% Alloy, Orion −20% Shipyard time and Draco doubles invasion rewards
- Six buildings: Starport, Barn and Defense Tower are public; Lumber Mill, Refinery and Shipyard are personal. Owned, living adult cattle work at the Lumber Mill or garrison the Tower (Tower Lv1–5 lets each member garrison 1 / 1 / 2 / 2 / 3 cattle); one cow can hold only one Sandbox job, but it is not locked out of Rangeland or Trek. Personal buildings under construction can use construction boosters (each cuts 30 minutes, 100 IRT each, burned on purchase and on use; public buildings cannot be boosted)
- Cross-game output: Barn Lv1–5 gives every planet member +2% to +10% Milk Factory hashpower. The daily milk pool is fixed, so this redistributes shares with zero issuance. The Shipyard turns matching Trek parts + Alloy (+ a blueprint at tier III) into five tiered flagship modules that take effect in Trek while held in the wallet. The Refinery can also recycle ore into IRG (Iron 1 → 4, Crystal 1 → 12, Core 1 → 32, ≤ 2,000 per address per day)
- Invasions: guild planets are attacked every day at the fixed hours 12:00 and 20:00 (UTC+8); operations can temporarily add extra on-the-hour waves (expect some during the beta). Defense = Tower base defense + Σ garrisoned cattle (attack + defense) ÷ 100; holding the line pays each garrisoned member 5–20 Alloy. Planets with neither a Barn nor Tower have newcomer protection; coordinate land is never attacked. A loss removes 30% of unclaimed Timber; three consecutive losses impose 12 hours of martial law and −20% lumber output
- Economic rule: every IRG and material cost for construction, upgrades, refining and module crafting — and the IRT for construction boosters — is burned on-chain. Timber (140) is the only new material and ore recycling is the only new IRG faucet (daily cap, same budget as Trek drops); Alloy (141) and modules (150–164) transform existing inputs. Timber, Alloy, construction boosters (142), modules and Coordinate NFTs are tradable
All output lands in the Reward Center first (one-click claim merges it into a single wallet transaction) and is then minted to your wallet; the envelope in the HUD is your mailbox and the top-left avatar is your Sandbox Profile. Building, refining, crafting modules, repelling invasions and collecting in Sandbox count toward the tenth Play XP dimension, Construction, capped at 10 XP a day (see section 5.3). Blueprint Workshop / UGC, Starport population and tax caps, and deep-space jumps belong to S6+ and are not part of the live first phase.
Two tokens: IRT and IRG
IRT · the hard asset — Fixed supply of 1 billion, never minted further. Earned from milk, Arena wins, season rewards and guild rewards; spent on breeding, starring up, expansions and tech.
IRG · the game currency — A consumable currency issued by demand. Earned from quests, PVE chests, check-ins and interstellar mining; spent on forage, breeding and other daily costs.
October 1 to December 31, 2026, on the Sepolia testnet, every feature free. Your real play, invites and feedback during the beta are recorded as XP, and IRT plus in-game items are airdropped by XP share at mainnet launch.
