It's like a sea battle, in only one dimension.

You can play with a bot or with a live adversary located in the same wi-fi network.
The game does not use the Internet. The game transmits data only on the local network (only when playing with a person).

To play, you must install any browser. The game will launch in the default browser.

The game launches a local http server, one or two players can join it. Players cannot exchange messages; only moves made are forwarded.
