Free to play. No purchase, no deposit, no house edge — sponsors fund every prize.

Try it in five minutes

Everything runs on Solana devnet.

Nothing here costs real money. You need an Android phone and Phantom.

1

Install

Get the APK from the latest release and install it on a Seeker or any Android 8+ phone.

2

Phantom on devnet

In Phantom: Settings → Developer Settings → Testnet Mode, then pick Solana Devnet. An empty wallet gets a Get free devnet SOL button in the app.

3

Pick, enter, win

Pick five, enter the current round, approve in Phantom. Within five minutes the numbers are drawn, a notification says how you did, and any prize is already in your wallet.

How it works

Three taps a round. That's the whole game.

No sign-ups, no deposits, no odds tables. Connect the wallet on your Seeker and play.

1

Pick five

Choose five numbers from 1 to 85 — or shake your phone for a quick pick. Your ticket is free.

2

Watch the draw

When the timer ends, ORAO VRF randomness on Solana draws the winning five. The balls turn over one by one.

3

Get paid

The best match takes the pot, ties split it. The prize lands in your wallet automatically — nothing to claim.

Provably fair

Nobody picks the numbers. Not even us.

The draw is a commit–reveal on ORAO VRF randomness, enforced by the Goldgrid program. Every step is a public Solana transaction you can check.

Entries close

Tickets are locked on-chain. Nothing can be added after this point.

Commit

A fresh randomness request is committed only after entries close, before anyone can know its answer.

Reveal

The program accepts only the answer to that exact request — an answered request can never be swapped for another.

Score & pay

Every ticket is scored on-chain, winners are paid, deposits are returned.

Built for Seeker

One device, one free ticket.

On mainnet each ticket is tied to a Seeker Genesis Token, verified on-chain from its Token-2022 group membership. One Seeker can't pose as a thousand wallets, so the pot goes to real players.

  • Mobile Wallet Adapter — sign with the wallet already on your phone
  • Play round after round to build a streak: every 7 in a row adds a ticket, up to 5
  • Results arrive as a notification, even with the app closed
For sponsors

Reach every Seeker, all day long.

Sponsors fund the pot in SKR. Each ticket moves a fixed bonus from the sponsor budget into that round's pot, so the prize grows in front of everyone as they play. Rounds nobody wins roll over.

Why SKR

Prizes in the Seeker's own token.

Every Goldgrid prize is paid in SKR, the token of the Solana Seeker community. It only ever flows out to winners — nobody pays anything to play.

Why we chose it

  • It belongs to the players. Seeker owners already hold SKR, so a prize stays in the community that plays instead of arriving in a coin nobody here uses.
  • Free stays free. SKR is a prize, never a ticket price. Goldgrid takes no payment in any token, which keeps it a free draw and not a bet.
  • The money is visible first. Sponsors put SKR into the program's vault before anyone plays; every prize is backed by tokens you can see on-chain.
  • Paid like any token. A prize is a transfer straight to the winner's wallet, provable on Solana Explorer. The program speaks both SPL Token and Token-2022.

What it makes possible next

  • Sponsored rounds — a dApp or brand funds a pot and its name sits on that round, in front of every Seeker playing.
  • Featured draws — a bigger pot for a launch day, an event or a weekend.
  • Partner prizes — a sponsor's own token paid alongside SKR.
  • Seeker-only rounds — each ticket tied to a Seeker Genesis Token, already built into the program.
  • Streak rewards — playing round after round earns extra SKR, not just extra tickets.

On devnet the prize is Test SKR (devnet), a stand-in with no value (mint GNafN4…G9r8). On mainnet the same program is set up with the real SKR mint.

Security

Audited, tested on-chain, open source.

Everything here is checked against the live devnet program, not just in unit tests.

✓
Full audit, every finding fixed. 15 issues found and fixed, including a draw re-roll, before redeploying under a new program id.
✓
Payouts go only to owners. Anyone may trigger a payout; a claim redirected to someone else's account is refused on-chain.
✓
No keys with power in the cloud. The hosted crank signs with a fee-only key that holds no authority over the program.
✓
Schedules can't rewrite history. Retiming rounds may only move numbering forward; past rounds keep their stored times.

Your five numbers are waiting.

Install Goldgrid on your Seeker and play the next round — it starts in a few minutes.
