1. Claim a starting position

In the spawn phase, click land to create your nation. After spawning, your territory produces troops and gold over time.

2. Expand carefully

Click neutral land next to your territory to start a ground attack. Click an enemy border to attack that nation. The attack force slider controls the percentage of your current troops committed to each attack.

• Use 25–40% while learning.
• Keep troops in reserve instead of committing 100%.
• Watch the active attack cards; cancel a bad attack to recover unused committed troops.

3. Cross water and blocked borders

If land is unreachable because another nation or an island blocks the route, the game can send a boat. Right click a target and choose Boat for a targeted naval attack.

4. Manage workers and gold

The workers slider is an economy trade-off. More workers produce more gold, while fewer workers produce troops faster. Gold pays for troops and buildings.

• City: increases gold income; place it on safe interior land.
• Port: increases income and supports trade ships; place it near the coast.
• Fort: makes a border harder to capture; place it at vulnerable fronts and chokepoints.

5. Use diplomacy

Right click another nation to request an alliance, donate troops or gold, inspect its strength, or betray it later. Allies cannot be attacked until the alliance is broken.

6. Win the match

You win by controlling 80% of the land or by being the last surviving nation. Ranked leaderboards count only public ranked lobbies; private and single-player games are for practice.
