Terms of use

Solo, shared-device and online play

Gomoku, Go, chess, janggi, Othello and tic-tac-toe offer computer opponents, two-player play on one device, invitation-link online play and random matchmaking. Random matchmaking waits for another person; an immediate match is not guaranteed. Party games differ in player counts, controls and online support.

Rules by game

Tic-tac-toe requires three in a row on 3×3, four on 5×5, and five on 7×7 or 9×9. Go offers 9, 13 and 19 lines; random matches use 19. Follow the selected online mode’s time and rematch rules.

Stories and escape games

Read scenes and choose actions in stories; explore rooms and connect clues and tools in escape games. Check each work’s supported languages and horror notices. Homecoming Broadcast currently has Korean gameplay text.

Records on this device

Recent games, regular 2048 and Minesweeper progress and best records stay in this browser without automatic expiry. Daily records retain the last 30 days. Gomoku saves the latest unfinished game for up to 30 days and clears it when finished or restarted. Reversi and tic-tac-toe progress is lost when closing or refreshing. Records do not transfer automatically between devices or domains.

Chess · Janggi

The latest game is saved on the server for 30 days, up to 600 moves. Resume in the same browser and site address. No account or device sync. Deleting or blocking cookies loses access. Delete saves after using a shared device. Expired saves are cleaned during later save requests.

Language and privacy

The default URL is shown in Korean. Choose a translation from the language menu. We do not look up your location or send game content to a translation server. Your choice is saved in a site cookie for one year; delete it through your browser's site data settings.

Local story, escape and party records

Story and escape progress and settings, party rosters and sound settings are kept in browser storage by the relevant game. Use a game’s reset control, where available, or clear site data to remove local records. Records without automatic expiry may remain until you delete them. Online-room records are handled separately.

Online board-game records

Online play stores the game, room code, hashed participant keys and last connection times on the server. Rooms can be reopened for 24 hours after the last activity; expired rooms are cleaned up when rooms are created. Your key stays in this browser and a random-match ticket stays in the current tab. Clearing site data prevents you from returning as the same participant.

In friend matches, the name you enter is also saved on the server and shown to your opponent. Share room links only with intended players. The browser identity key has no automatic expiry; clear site data to remove it. Clearing browser data does not immediately delete server records.

Analytics settings

Google Analytics is used only after consent.

Sharing and contact

Results go to the chosen app or clipboard only when you press share or copy. Email inquiries send your address and message to the operator's inbox. You can also use the contact email for privacy requests.

Service changes and records

Games may change or pause for improvements or maintenance. Records are not certified rankings or prize scores. Recovery is not guaranteed after save failures or browser data deletion. External games follow their own rules and privacy notices.

Community

Be respectful. No personal information, ads or spam. Nicknames may be shared and do not verify identity.

Nicknames, posts and comments are public and stored on the server until deletion. Passwords are hashed and cannot be recovered. Reports are visible only to the operator.

The writing nickname is remembered in this browser. An IP hash and request count are used for up to one hour to limit spam. Reports remain as a moderation record; contact us to request deletion. Clearing browser data does not delete public posts.

Optional accounts, titles and moderation

2026-10-14

Local accounts store a username, nickname, verified email and one-way password hash. Email is used for signup verification and password resets; the recipient address and verification message are sent to our email provider, Resend. We do not store plain passwords or verification codes in the site database. Verification records expire after 10 minutes and are removed on later verification requests. Password or email changes revoke existing sessions. Local and social accounts are not automatically linked. Existing local members without an email must sign in and verify one before using email recovery. Account and verification data are deleted on account deletion. For accounts deleted while suspended, an email hash is retained until the restriction ends (one year for permanent suspensions). Rate limits use hashed IPs, usernames and emails in windows up to 15 minutes, plus daily UTC delivery totals; expired limits are removed on later requests.

Judge ranks count the first clear of each distinct trial, with a new rank every 10 trials. Earlier titles remain earned. Your highest judge rank is displayed by default; choose another earned title or hide it in Account. Posts and comments written while signed in publicly show your current title and icon, including older posts when you change your title. Editing or deleting member posts requires the author account and the post password.

All games are available without signing in. Signed-in members earn titles by finishing supported games, once per distinct game. Existing device saves are not transferred or synced to an account.

We use your provider account ID, chosen nickname, Google email, registration/sign-in times, consent version, completion times by game, titles and moderation history to operate account features. We never receive your social account password. Accounts using different providers are not automatically merged by email.

Records are kept in the site’s access-controlled database. Member cookies last up to 30 days; sign-in verification cookies last 10 minutes. Session tokens are stored as hashes. Account records are separate from optional analytics; member identity and nicknames are not added to analytics events.

Deleting your account removes your profile, linked identity, titles, completion records and moderation history. Community content and device saves require separate deletion. If you leave while suspended, only a one-way identity digest and restriction expiry are retained until the suspension expires (one year after leaving a permanently suspended account); expired entries are deleted during subsequent account processing.

The operator may record a reason and temporarily or permanently suspend accounts for illegal content, infringement, harassment, spam, attacks, account theft or manipulated records. Suspension blocks member achievements, profile changes and community writes while signed in. Anonymous games remain available. You can see the reason and duration in your account and appeal through Contact.

Registration and its required data processing are optional for playing. Agreement is not marketing consent. Completion records rely on client completion events and are not server-certified rankings or prize results.
