Need help with Kingside Break? Email support.yujamgames@gmail.com.
To help us investigate, please include:
- a short description of the problem and the steps that caused it;
- your Windows version and Kingside Break version;
- whether the game was launched through Steam;
- the screen, campaign level, or downloadable content involved; and
- a screenshot or log file if it helps reproduce the issue.
Please remove personal or unrelated information before attaching a screenshot, save, or log. Never
send your Steam password, payment-card information, authentication code, or another account secret.
1. Close Kingside Break and restart Steam.
2. In your Steam Library, right-click Kingside Break, select Properties, open Installed
Files, and select Verify integrity of game files.
3. If the screen is cropped or text overlaps, start in windowed mode and select a supported
resolution under Settings, then select Save.
4. If owned cosmetic DLC is missing, confirm it is enabled for Kingside Break in Steam, allow the
download to finish, and restart the game online once so ownership can be restored.
5. If the issue remains, email support with the details listed above.
Kingside Break stores progression locally. On Windows, the expected save folder is:
%USERPROFILE%\AppData\LocalLow\YuJam Games\Kingside Break\
The primary progress file is progress.json. Close the game before copying or restoring save data.
Back up the whole folder before manually changing anything.
Kingside Break does not currently support Steam Cloud. Uninstalling Windows, deleting the local
profile, or moving to another PC may require a manual backup.
Steam processes Kingside Break purchases, refunds, downloads, and account access. Visit
https://help.steampowered.com for payment, refund, or Steam-account problems. YuJam Games cannot see
your Steam password or full payment details and cannot override Valve's refund decisions.
Kingside Break DLC changes appearance only. It does not change chess rules, AI strength, campaign
access, rewards, or player power.
If an owned pack is not appearing, confirm that Steam has installed and enabled it, then launch the
game online once. If it remains unavailable, email support.yujamgames@gmail.com with the pack
name and a description of what the game displays. Do not email payment-card details.
See the Privacy and Legal pages on this site for information about local save data, Steam,
support communications, copyright, third-party materials, and cosmetic DLC rights.
