Make a world.
Give it a coin.
Start with a game idea, play it in your browser, then connect a coin when you're ready. Here is how each step works.
Jump straight in.
Open Discover, pick a game and press Play. You can play the browser collection without a wallet. The game panel shows your goal and controls; use the on-screen controls on a phone, or the keyboard controls shown beside the game on desktop. You can restart, share a link or open the Roblox lobby from the player when a Roblox link is available.
Open the Pumpblox Roblox lobby ↗. Roblox runs through its app or supported client. The browser game and Roblox lobby are separate ways to play.
Describe the adventure.
In Build a game, describe the setting, goal and challenges. The builder turns a supported idea into a playable quest with stages, objectives, hazards and a finale. Try a specific idea, such as “a rooftop relay with switches, moving hazards and a final portal.”
Play the generated quest in your browser and share its link. A free game is saved on your device; it is not automatically a launched coin game. Generation uses supported game mechanics, so it cannot create every imagined feature or a unique game engine.
Review before Phantom opens.
- 1Set up the coin
At Launch coin, add a name, ticker, description, coin image, initial buy amount and game prompt. You can ask Pumpblox to suggest a game idea.
- 2Review your quest
Pumpblox prepares the game before the wallet transaction. Check its title, stages and ending. Edit the idea if it does not fit your coin.
- 3Approve in Phantom
When you continue, Phantom asks you to sign and send a real Pump.fun coin launch. The initial buy, Solana network fees and any Pump.fun fees cost SOL. Review the wallet transaction carefully.
Never share your recovery phrase. Pumpblox does not ask for it.
Your coin gets a game entry.
After the launch transaction is finalized and verified, Pumpblox connects the generated quest to that coin and adds it to Launched coin games. Open the entry to play and share it. If confirmation is delayed, use the on-page “Check my launch again” action. The game is linked to the verified coin; a failed or unverified transaction does not create a public game entry.
Use Bring your coin here. Paste the coin link, connect the wallet that created it and sign a free ownership message. If automatic lookup cannot find the launch, add its transaction signature. This is a separate claim step after launching elsewhere.
One lobby, many coin games.
The published Pumpblox Roblox experience ↗ reads the public coin-game catalog. New verified games are meant to appear as selectable entries in that shared lobby after its next refresh. Each coin does not create a separate Roblox experience or Roblox listing.
The lobby and installer are published, but a newly generated quest has not yet been directly play-tested in the published Roblox place. Check the coin in the Roblox lobby and test its objectives before telling your community its native Roblox version is fully playable. Its browser game remains available from the coin catalog.
Open Pumpblox on Roblox ↗Help shape the next update.
Coin holders can open a launched game's suggestion area, connect Phantom and sign a free message to prove they hold the coin. Suggestions go to review; they do not instantly change the live game. The Holders page explains current verification, proposals and voting. A wallet signature for verification is not a paid transaction.
Before you start.
Do I need a wallet to play?
No. Browser games can be played as a guest. A compatible wallet is needed for a coin launch, ownership verification and holder features.
Can I change my game after the launch?
Coin holders can suggest improvements, but suggestions do not update a published quest automatically. Creators of older imported runner games can claim and replace those legacy games after verification; an already published custom quest is not overwritten through the claim flow.
Will my coin appear as its own Roblox game?
No. Coin games appear inside the shared Pumpblox Roblox lobby, which reads the Pumpblox catalog. The separate browser catalog lists the coin games on this site.
What if my coin does not show up?
First check the launch status and use “Check my launch again” on the launch page. If you launched directly on Pump.fun, use “Bring your coin here” with the creator wallet and, if needed, the launch transaction signature.
