All the rules. All the workings. None of the fine-print surprises.
Gramps is a three-digit numbers game on Robinhood Chain.
Pick TSLA, NVDA or SPY, choose 000–999 and select Straight or Box. Each ticket costs 1 real USDG plus wallet network fees.
Current rounds use operator settlement. The operator supplies the price and can choose the published value; the contract cannot prove its correctness. Chainlink is not active for these rounds.
Read the round’s settlement mode before approving or buying.
The published reference price is truncated to whole cents.
Example: $412.87 becomes 41287 cents, then 287. $410.07 becomes 007. These are arithmetic examples, not reported results.
The reference is not the official exchange closing print. Price digits are not guaranteed to be uniformly random.
Leading zeros count.
Straight matches the exact order; Box matches any order.
A Straight 287 wins against 287 only. A Box 287 also matches 782.
Repeated digits matter: Box 007 matches 070 and 700, but not 077. A Box ticket receives one winning share, not six.
One ticket, one category.
Straight receives 70%, Box 20%, and the fee is 10%.
Each book has its own pool. Winning tickets split their category allocation. Payouts depend on the actual pool and winning-ticket count.
A category without winners carries its allocation forward. Payout division rounds down to USDG base units; remainder carries within the category. Split-rounding remainder goes to Box.
Fees accrue at settlement. Cancelled rounds refund ticket prices without taking the settlement fee. Earlier carry remains with its book.
No fixed returns and no fabricated liquidity.
Check the cutoff recorded for your round.
The admin schedules regular sessions for 4 PM America/New_York. The reference time is cutoff + 60 seconds. The current calendar covers 2026 weekdays and NYSE holidays; early-close sessions are excluded.
The contract enforces the recorded cutoff, not the exchange calendar. Outside 2026 the scheduling widget reports its limitation.
Publication requires an operator transaction and may occur after the reference time. If no settlement succeeds within 24 hours after cutoff, anyone can make the round refundable.
A calendar countdown is not proof of settlement.
Tickets and prizes use USDG on Robinhood Chain, chain ID 4663.
The configured token is 0x5fc5360D0400a0Fd4f2af552ADD042D716F1d168, with 6 decimals. Ticket price is 1,000,000 base units.
Approve 1 USDG, then confirm the purchase separately in MetaMask. ETH pays network fees. Never enter your wallet private key into this site.
Ticket references are saved in this browser. Restore a missing reference using its purchase transaction hash. Ownership, prizes and refunds are read from the contract.

The active contract is 0x92D46F0Fd770999A23DBa6B14889D97875b34eA3.
Operator rounds use the first valid Robinhood bid/ask midpoint captured with a source timestamp from cutoff + 60 through cutoff + 90 seconds. The operator publishes the value and an evidence hash. The hash is a record, not proof that the price is correct.
The capture service must be running during that window. Missing capture leads to delayed settlement or the 24-hour refund path; it does not justify inventing a price.
After verification of all three signed feeds, the operator may switch future rounds to Chainlink V11. This switch is one-way. Existing rounds keep their original mode.
Chainlink rounds require a verified mid-price report covering cutoff + 60 seconds, within the contract’s report freshness and market-status checks. Operators cannot use the operator-price function for those rounds.
Automated checks are not an independent audit. Contract bugs, operator conduct and market prices can affect outcomes.
The purchase page displays the mode recorded for the round.
18+ only. No guaranteed winnings.
Only play where permitted and with money you can afford to lose. Do not borrow or chase losses.
Stock-price digits are not uniformly random. Neither operator settlement nor Chainlink guarantees a fair distribution, contract safety or a win.
If play stops feeling like entertainment, stop and seek support.
Real USDG is spent when you confirm a purchase.
