Subnet Slinger (game)

What it does: a lighthearted arcade break — subnets rain from the sky and you sling the right answer before they hit the dirt. Miss three and you're dusted. It's also sneaky CIDR practice.

What you need: nothing — just play.

Safe to run: yes, it's a game. It touches no network and saves nothing but your score.

Reading results: your score and streak. If the subnet math trips you up, the Subnet Calculator tool (and its doc) explains how network/broadcast/host ranges work.
