Copper Mine — Mining Code
Last updated: June 2025
Every mine operates by a code — it keeps the shafts safe and the claim honest. These are Copper Mine's rules. By putting on the helmet, you agree to work by them.
The mine
Copper Mine is a free, browser-based memory card game. Match ore, tool, and treasure pairs, build your ore score, and stake your claim. No payment. No account.
All prospectors welcome
Miners of every age are welcome underground. Copper Mine is non-violent, gambling-free, and appropriate for all audiences.
Ore score
Points accumulate per matched pair, with a vein multiplier for consecutive successes. Ore scores are session-only and carry no monetary value.
No wagering on the vein
Copper Mine contains no virtual currency, no loot systems, no betting mechanics, and no randomised prizes.
Intellectual property
All game assets belong to their creators. Personal play is freely permitted. Commercial use requires prior written permission.
Prohibited conduct
Automated bots, exploit tools, and deliberate disruption of other miners' sessions are strictly prohibited.
No guaranteed strike
Copper Mine is provided as-is. We hold no liability for indirect losses from gameplay or service outages.
Code revisions
These terms may change. The date above marks the current version. Continued play is acceptance.
