Getting started
- Choose Vault Duel in Friend Game.
- Divide twelve chips among vaults worth 10, 8, 6, 4 and 2 points, then seal your move.
- Send friends the participation link. Keep the private management address to yourself.
- Each friend allocates twelve chips. The higher allocation wins a vault's points; ties split them. The total determines the match outcome.
- Only the outcome is shown while a challenge is open. Closing permanently stops new entries and releases the allocation, vault scores and commitment evidence.
- Create a new challenge for a different allocation. Earlier match conditions and results do not change.
Questions and answers
When are challenge records removed?
Challenge access closes 90 days after creation, with daily technical cleanup. Hosting recovery history may retain data for up to 30 more days after technical deletion. See the Portal privacy notice for erasure requests and processing details.
Does everyone need to be online together?
No. The creator seals one move and friends can challenge it later. Each friend has a separate one-on-one match; they do not compete for a shared pool.
Can previous results reveal the allocation?
While entries remain open, the opponent's allocation, vault-level scoring and exact totals stay hidden. Outcomes still provide clues, so secrecy cannot be absolute. Full evidence is released only after new entries are permanently closed.
Can a sealed allocation change?
No. A new move needs a new challenge. Older 6/4/2-point challenges keep their original rules and results.
Are player names verified?
No. Names are chosen by participants. There is no account identity verification or authoritative leaderboard.
