Last updated: June 2025
Before you descend, read these rules. Crystal Cave is a place for everyone, and these terms help keep it that way.
The expedition
Crystal Cave is a free, browser-based memory game. Flip crystal tiles, find matching gem pairs, and light up the cave. There is nothing to buy and no account required.
Open to all explorers
Players of every age are welcome. The game has no violent content, no gambling, and nothing unsuitable for younger audiences.
Gem points
Matching pairs earns gem points, with combo bonuses for successive matches. Points exist only within the current session and have no monetary value.
No wagers in the cave
Crystal Cave contains no betting mechanics, virtual currency, loot boxes, or randomised pay-to-win elements.
Intellectual property
All creative and technical elements of Crystal Cave belong to their creators. You may play freely for personal use. Redistribution or commercial use requires written permission.
Prohibited conduct
Automated bots, exploit scripts, and intentional disruption of the service are not permitted.
As-is provision
The game is offered as-is without warranties. We accept no liability for indirect harm arising from use.
Rule updates
Terms may be amended. Continued play after any amendment means you accept the revised version.
