For parents

What your child will and will not find in NAXAR.

The game

NAXAR is a free physics cave game in the browser, on phones and computers. Every grain is a material: sand pours, water flows, lava crusts into basalt when it meets water, fire spreads through old timber and powder kegs blow walls open. Each cave has one goal: reach its crystal, as fast as you can.
