Trading and game history
What can be traded, when it can be traded, and what never changes
Trading during an active game
While a game is active, including its final 48-hour window, cards from that game can be traded for other cards from the same game. This keeps the live competition self-contained: a current-game card cannot be swapped for a historical card from a different completed game while the current game is still being decided.
A successful trade changes which account currently owns the traded cards. Players should review the offered numbers before confirming a trade because ownership is the core thing being exchanged.
What happens after Number 1 is found
When Number 1 is allocated, the winner and final competitive standings lock immediately. A 48-hour final window then begins. Eligible random claiming and same-game trading can continue during that period while the game's conclusion is finalised.
At the end of the window, the game is archived and the next game can begin with a fresh number pool. The archived game records who won and where the competitive standings finished.
The Lifetime Market
Once a game's final window has ended, its claimed cards become eligible for the Lifetime Market. Lifetime trades can cross completed games. For example, a player may be able to trade a Game 1 card for a Game 2 card after both games are completed.
This creates a distinction between the history of a card and its current owner. The card keeps its connection to the game in which it was originally claimed even if the owner later changes.
Historical results do not move with the card
A later trade of a completed-game card does not retroactively change the original winner, finishing order or archived standings. Game history is intended to be a record of what happened at the time the game ended.
This means a player can collect an interesting historical card without becoming the historical winner who originally held it when that game finished.
The Marketplace is not a cash resale exchange
The normal First To One Marketplace currently supports number-for-number trading. First To One does not currently provide player seller payouts, and it does not promise to buy cards back from players. Numbers cannot be redeemed with First To One for cash.
Players should be cautious about off-platform offers involving money, gift cards, cryptocurrency or other payment. First To One cannot make an off-platform deal safe simply because the people involved also have First To One accounts.
Exact Number Auctions are different
If First To One expressly enables Exact Number Auctions during a game's final 48-hour window, the operator may offer one specified unclaimed number under the auction rules. That is a direct First To One sale of a previously unclaimed number. It is not a player listing and it does not turn the normal Marketplace into a cash-resale system.
Where an auction is enabled, the relevant price, bidding, payment authorisation and settlement rules are described in the About & FAQ, Terms and Refund Policy.
Safer trading habits
Before confirming a trade, check the exact number cards being offered and requested. Do not share passwords, email verification links, full payment-card details or security codes with another player. If someone claims they need account credentials to complete a trade, do not provide them.
If a trade, payment or account action does not look right, use the published Support details rather than relying on an off-platform message from another user.
