About

Regnarium is built for the player who says “I want to play a 4X but I don't have six hours”: explore, expand, produce and defeat your rivals on a 20×24, 480-hex map — all in a single session, within 60 turns.

The game runs entirely on your device. No account, no server, no ads, no tracking. It plays the same in airplane mode.

Combat is diceless: the preview you see before attacking is the actual calculation. The opponent AI cannot act outside the commands you have, and fog applies to it too — it knows what it sees and guesses the rest.

In-game art was produced with AI assistance and reworked by hand; the game never contacts an AI service while running.
