An initial game offering (IGO) is a pre-launch sale of a blockchain game's tokens or NFTs, usually run through a crypto launchpad. It raises money and builds a player base before the game ships, and it carries the same risks that made many 2021-era game tokens collapse.
IGOs grew out of the initial DEX offering (IDO) model during the play-to-earn boom of 2021. The idea was appealing: instead of selling to venture funds, let the future community buy in early. In practice, many IGO buyers were speculators who sold as soon as tokens unlocked, and games that weren't ready faced an immediate price slide. Understanding why helps both teams planning a raise and players deciding whether to participate.
How an IGO works
A typical IGO has five moving parts.
1. The launchpad
Specialist gaming launchpads, and general ones with gaming sections, vet projects, host the sale page and provide the audience. They usually take a fee and sometimes an allocation of tokens. Launchpad due diligence varies widely; a listing is not an endorsement worth relying on.
2. Tiers and eligibility
Most launchpads require buyers to stake or hold the launchpad's own token to reach an allocation tier. Higher tiers get guaranteed or larger allocations; lower tiers enter a lottery. Buyers usually pass KYC, and residents of certain countries, often including the US, are excluded.
3. What's sold
- Fungible game tokens (often ERC-20 or BEP-20), typically the governance or premium currency.
- NFTs, such as characters, land, items or "mystery boxes" that reveal a random item. These are commonly ERC-721 or ERC-1155.
- Sometimes both, with NFTs granting early access or in-game advantages.
4. Vesting and the TGE
At the token generation event (TGE), a percentage of purchased tokens unlocks; the rest vests over months, often after a cliff. Team and investor allocations follow their own, usually longer, schedules. The unlock schedule matters more to price behavior than almost anything else in the sale.
5. Liquidity and listing
After the sale, the project seeds a liquidity pool on a DEX and sometimes lists on centralized exchanges. Thin liquidity plus large unlocks is a common recipe for a sharp sell-off.
IGO vs other ways to fund a game
| Route | Who funds | What they get | Main risk |
|---|---|---|---|
| IGO | Retail via launchpad | Tokens or NFTs, early access | Speculative buyers, regulatory exposure, price pressure at unlock |
| NFT pre-sale (direct) | Community on your own site | Game assets | Smaller reach, same regulatory questions |
| Venture or publisher funding | Funds, publishers | Equity or token warrants | Dilution, investor control |
| Crowdfunding or early access | Players | Copies of the game, perks | Smaller raise, delivery obligations |
| Free-to-play first, token later | Revenue or investors | Token only once the game has players | Slower, but grounded in real usage |
What the 2021 boom and 2022 bust taught
Axie Infinity's play-to-earn economy showed that players would spend on NFTs that could earn tokens, and dozens of games raised through IGOs on the strength of that model. By 2022, the model had broken: Axie's own reward token fell steeply, its Ronin bridge was hacked for over $600 million, and many IGO tokens traded far below their sale price within months. Several lessons stand out:
- Selling tokens before the game exists invites speculation, not players. Buyers who are there for a quick multiple sell at the first unlock.
- Play-to-earn economies need sinks. When the only reason to buy the token is to earn more of it, the economy depends on new entrants. Sustainable designs need players spending for fun, cosmetics or competition.
- Development timelines slip. Games take years. A token that launches two years before a playable build has two years of unlocks and no utility.
- Launchpad tier systems reward capital, not players. Allocations went to whoever staked the most launchpad tokens, often bots and farmers using many wallets.
Since then, more studios ship a playable game first, use NFTs for cosmetic or tradable items rather than for earning, and introduce tokens only once an economy exists. The guides on Web3 game development and NFT gaming platforms go deeper on economy design.
Running an IGO responsibly
- Have a playable build. At minimum a public demo or playtest. It filters for buyers who care about the game.
- Get legal advice on structure. In the US, the SEC's analysis of whether a token is an investment contract applies regardless of the word "utility". In the EU, MiCA requires a crypto-asset white paper and has rules for offerings to the public, though unique, non-fungible NFTs are mostly outside its scope. Decide early which jurisdictions you'll exclude.
- Design the token supply honestly. Publish total supply, allocations, vesting and unlock dates. Avoid large TGE unlocks for any group, including your own.
- Make the NFTs useful in the game. Items should matter for play or expression, not only for resale. Disclose odds for mystery boxes; some jurisdictions treat random paid rewards as gambling-adjacent loot boxes.
- Choose the launchpad carefully. Ask about its vetting process, buyer KYC, anti-bot measures, fees and token allocations it expects.
- Audit the contracts. Sale, vesting, staking and NFT contracts are frequent targets. See why smart contract audits matter.
- Plan liquidity and communication. Seed enough liquidity, announce unlocks in advance, and report development progress against a public roadmap.
The technical stack of an IGO
- Sale contract. Accepts payment (usually a stablecoin), enforces caps per wallet and per tier, and records allocations. Merkle-tree allowlists keep gas costs low for large participant lists.
- Staking and tier contract. Tracks how much launchpad token each wallet has staked and for how long, often with snapshots to prevent last-minute staking.
- Vesting contract. Releases tokens on a schedule with cliffs and linear unlocks; buyers claim over time.
- NFT contracts. ERC-721 or ERC-1155 with reveal mechanics; randomness should come from a verifiable source such as a VRF oracle rather than block data.
- Off-chain services. KYC provider integration, geo-blocking, sybil detection and a dashboard for claims.
- Multichain support. Many launchpads run on several chains, which adds bridge and deployment complexity.
For platform-side architecture, see the IGO launchpad development guide and the broader launchpad development guide.
Defending the sale against bots and farmers
Allocation-based sales attract automated buyers who split capital across many wallets to beat per-wallet caps and lotteries. Defenses work in layers:
- KYC-bound allocations. Tie each allocation to a verified identity, not a wallet, and check that one person doesn't register several wallets.
- Staking snapshots. Take tier snapshots at random or pre-announced times well before the sale, and require a minimum staking duration, so capital can't be borrowed briefly to reach a tier.
- Signed allocations. Have the backend sign each buyer's allocation (EIP-712 typed data), and have the sale contract verify the signature, so allocations can't be forged or reused across wallets.
- Player-based eligibility. Weight allocations toward wallets or accounts with real playtest history rather than only staked capital. This aligns the buyer base with the people the game is for.
- Fair launch of liquidity. Sniping bots target the first block of a new DEX pool. Coordinate listing time, consider anti-snipe measures during the first minutes, and avoid announcing pool addresses early.
What to measure after the sale
The IGO is the start of the obligation, not the finish. Healthy projects track and publish metrics that reflect play rather than price: daily and monthly active players, retention by cohort, the share of token and NFT purchases made by players versus traders, and how much token value flows into sinks compared with rewards emitted. If emissions consistently exceed sinks, the economy is subsidizing sellers and needs to be rebalanced before the next unlock, not after it.
How players should evaluate an IGO
- Is there a game you can play today, and is it fun without the token?
- Who is on the team, and have they shipped games before?
- What share of tokens do the team and investors hold, and when do they unlock?
- What are the token's sinks: what will players spend it on, and why?
- Are the contracts audited and the admin keys controlled by a multisig?
- Is the sale open to you legally where you live?
Treat any IGO purchase as high-risk money you could lose entirely.
Frequently asked questions
What's the difference between an IGO and an IDO?
An IDO is a token sale on a decentralized exchange or launchpad for any project. An IGO is the same idea specialized for games, often including NFTs and early game access.
Are IGOs legal?
It depends on the structure and the buyers' jurisdictions. Many tokens sold in IGOs could be treated as securities, which is why launchpads often exclude certain countries. Get specific legal advice.
Why did so many IGO tokens fall in price?
Large unlocks, speculative buyers, games that weren't ready, and economies that relied on new players buying in to support rewards.
Do I need a token to launch a blockchain game?
No. Many games use NFTs for items with no fungible token, or launch with no on-chain assets and add them once there's a player base.
What contracts does an IGO need?
Typically a sale contract, staking or tier logic, a vesting contract and the game's token or NFT contracts, all of which should be audited.
