How to Play Territorial.io
Begin each match by selecting an unoccupied starting location on the map. Your territory automatically generates balance (troops) through compound interest and fixed income. Expand by attacking adjacent regions using the percentage attack bar at the bottom of your screen. Balance territory expansion with economic growth—expanding too fast leaves borders vulnerable, while accumulating too much balance wastes growth potential. The first 107 seconds are critical, as interest rates are highest during this golden period.
Game Modes
| Mode | Description |
|---|---|
| Battle Royale | Free-for-all mode where everyone competes against each other. Most popular mode with real players and bots. Goal: be last survivor or control 99%+ of map. |
| 1v1 Mode | One-on-one duel plus bots. Requires different playstyle focusing on economic growth, timing, and cutting off opponent's expansion routes. |
| Full Send Disabled | Similar to Battle Royale but limits attack intensity to approximately 20%. Cannot rapidly launch consecutive attacks, encouraging strategic expansion. |
| Team Games | 2-8 teams compete. Teammates share same color, cannot attack each other, and can donate balance. Requires coordination and resource sharing. |
| Zombie Mode | All players on white team fight powerful black team zombie bots. Most challenging mode requiring cooperation, slow opening strategy, and coordinated defense. |
| Custom Lobbies | Create private games with custom rules and settings. |

Balance System
| Concept | Explanation |
|---|---|
| Interest Phases | Starts at 7% for ~107s then decays to 1%; early game is critical. |
| Optimal Density 100 | Balance ≈ territory pixels × 100 is the red-number sweet spot. |
| Max Capacity 150 | Balance cap ≈ territory pixels × 150; excess growth stalls. |
| Hidden Taxes | Land 1.17%/attack, boat 3.125%, move 0.78%, donate 6.25%→0. |
| Opening Strategy | Greenbiscuit: 10→12→15→17→20→20% cycles during the first 107 seconds. |
| Clan Points | Alliance wins and Contest mode award clan points for leaderboards. |
| PC vs Mobile | Mechanics identical; PC adds mouse/keyboard and large-screen awareness. |
Attack Mechanics
| Mechanic | Description |
|---|---|
| 2:1 Rule | Aim for double the enemy's balance when conquering for efficient captures. |
| Boat Capture | Use multi-boat timing to increase captured share when landing on coasts. |
| Attack Rhythm | Avoid spam; time larger attacks after enemy full-sends or low balance. |
| Target Selection | Prefer weak bots, overextended players, and enemies engaged on other fronts. |
| Border Management | Minimize borders; use oceans/mountains to reduce incoming attack directions. |
| Donation Timing | Donate only when decisive; early donations suffer 6.25% tax decreasing over time. |
| Boat Taxes | Boat creation 3.125%, movement 0.78%; plan paths to minimize losses. |
