Terms of Service

Last updated: February 11, 2026

Welcome to Sadari.org. By accessing and using this website ("Site"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms, please do not use the Site.

1. Description of Service

Sadari.org provides a free online ladder lottery game (also known as 사다리타기 in Korean or Amidakuji in Japanese). The game is a random selection tool designed purely for entertainment purposes. The Site allows users to create and play ladder lottery games directly in their web browser without requiring registration or payment.

2. Entertainment Purposes Only

The ladder lottery game provided on this Site is intended solely for entertainment, amusement, and casual decision-making among friends, family, or colleagues. The game should not be used for:

  • Gambling or wagering of any kind
  • Making legally binding decisions
  • Financial decisions or transactions
  • Any purpose where the outcome has significant legal, financial, or personal consequences

You acknowledge that the game is a tool for fun and informal group decisions, and you assume full responsibility for how you choose to use the results.

3. Randomness of Results

The results generated by the ladder lottery game are determined by a random or pseudo-random process. Each game produces outcomes based on the configuration of horizontal rungs placed between vertical lines. While the algorithm is designed to produce fair and unbiased results:

  • We do not guarantee that results are perfectly uniformly distributed in every instance
  • Results are generated client-side in your browser and are not stored or recorded by us
  • Each game is independent; past results do not influence future outcomes
  • The randomness is based on computational algorithms, which are pseudo-random by nature
