Perfect for team assignments, prize distribution, shift scheduling, and committee role allocation.

Participants submit their ranked preferences (1st choice: A, 2nd choice: B...), and the system uses a fair draft algorithm to determine the optimal allocation. If demand exceeds capacity, a fair lottery is held, and those who miss out are automatically re-entered for their next preference. This eliminates bias and maximizes satisfaction for everyone.

Draft Allocation Rules

How the fair allocation algorithm works:

  1. 1. Priority on 1st Choices
    Everyone's 1st choice is processed first. If the number of applicants exceeds the capacity, winners are decided by a fair lottery.
  2. 2. Rolling Allocations
    Those who miss their 1st choice proceed to their 2nd choice. They are entered into the lottery for their 2nd choice only if slots remain. This process repeats until everyone is assigned or choices are exhausted.
  3. 3. 'Yield to Others' Option
    Participants can check "Yield to Others" when submitting. If a tie-breaker lottery occurs for the same rank, priority is given to those who did not check this box. Use this if you are willing to let others go first.
    (e.g., Your 1st choice has lower priority than someone else's 1st choice, but higher priority than someone else's 2nd choice.)
  4. 4. Final Adjustment
    Anyone unmatched after all preferences are processed will be randomly assigned to remaining slots.

*This transparent process eliminates manipulation and respects everyone's preferences as much as possible.

Cryptographically Secure Fairness

Powered by industry-standard CSPRNG algorithms to guarantee mathematical unpredictability.
Even when preferences conflict, the tie-breaking lottery is strictly fair. Zero bias, zero manipulation.

Member Pre-registration / Entry

Choose between registering members in advance or allowing participants to enter their own names freely.

Common Use Cases

  • Seminar/Lab Assignment: Fairly distribute limited slots.
  • Role Distribution: Assign duties for school festivals or PTA.
  • Shift Scheduling: Decide roster based on preferred dates.
  • Course Selection: Balance popularity for training sessions.
  • Prize Distribution: Distribute goods prioritizing preferences.

Trusted Algorithm

Draft Room adopts an allocation logic similar to a professional sports draft conference.

It eliminates human subjectivity and performs allocation through a highly transparent process where anyone can see that "rules were followed."

This reduces dissatisfaction ("Why did I get this?") and increases group consensus.
