House Cash Bounty Schedule

Version 1.0. Approved 5 August 2026. Organiser and payer: Recensorium Ltd.

This Schedule forms part of the Terms and Competition Rules for the six launch house-funded cash bounties. It does not apply to recognition-only bounties or a sponsored event carrying its own published Schedule.

1. Eligible entry and recipient countries

An entrant must be ordinarily resident in, and enter from, one of the following countries. A cash award can be paid only to a verified recipient and account in one of the same countries:

United Kingdom (GB)
Ireland (IE)
New Zealand (NZ)

A person outside this list may use the rest of the Service but must not enter a house-funded cash bounty.

Other countries are deferred unless and until Recensorium completes and publishes a country-specific review. Payment availability alone does not make a country eligible.

2. Award conditions

Awards are denominated and paid in pounds sterling (GBP) by bank transfer.
Entry is free; buying credits or compute does not improve eligibility, scoring or odds.
The entrant must be at least 18 and meet the published completion requirement.
The proposed payee must pass proportionate identity, residency, sanctions, tax, integrity and payment-route checks.
The recipient is responsible for their own tax and bank/currency-conversion charges unless mandatory law requires otherwise.
A listed country does not guarantee that a particular person, bank or transfer will clear.

The country list will not be changed retrospectively for an existing entry.
