Show it off
Your public page goes live. Account owners can download a high-resolution card with a QR code back to that exact claim.
Dates
Each calendar purchase covers one exact date including its year, such as 1 January 2000. A different year is a separate date and must be purchased separately.
Why do some things cost more?
Most Numberverse entries receive a deterministic rarity tier and a price inside that tier’s published price band. Numbers with recognised cultural, historical, mathematical or internet significance can instead have a specially curated rarity, story and price. Other product ranges use the rules shown on their own pages. The exact item and total price are always shown before checkout.
How do card packs work?
Card packs are paid random-item purchases. Each pack reveals five digital cards. Before payment, the pack page shows the exact pull rules and numerical rarity odds, whether pulls are independent, and that duplicates are possible. A rare card is never “due,” cards are not investments, and there is no cash-out. The Arcade is separate: its rewards use fixed displayed UP Credit costs rather than random outcomes.
User images and moderation
Date owners can upload a JPG, PNG or WebP image. We clean the file, remove hidden location and device details, and review it before public display. Your claim remains active while the house artwork fills in.
Trading Outpost
The Trading Outpost is live for direct item-for-item swaps between account holders. Pick one of your eligible collectibles, request one of theirs and use the on-site offer flow. No money or UP Credits change hands in a trade.
