Terms of Service
Last updated: 2026
The service
Stack Fun is a free casual game offering core gameplay, leaderboards, and a daily challenge; difficulty parameters, skins, and events may change from time to time.
Accounts & data
Anonymous web accounts are derived from a browser fingerprint and only accessible from that device; WeChat accounts use WeChat-authorized login. Do not tamper with run data or use cheats - abnormal scores are flagged and may be removed from leaderboards.
Virtual items
Skins and other virtual items are for in-game display only - not redeemable for cash and not transferable.
Disclaimer
We aim to keep the service stable but are not liable for data loss or interruption caused by network or device issues outside our control.
Changes
We may update these terms; material changes will be announced on the site. Continued use means you accept the updated terms.
