Your first expedition

Create a room, invite a second signed-in account and Start expedition. Select your home star, build three ships, choose a nearby star and dispatch three ships. Both accounts press Ready; fleets travel and colonies produce income. Continue until your fleet arrives and captures the star, then build from your new colony.

Sign in to Tronsoft. Create a room and invite another account. Two humans must join before the host starts; add up to six computer empires, with eight empires total.

Each empire starts with a colony, 12 ships and 60 credits. Select one of your colonies to build ships (10 credits each), scan nearby stars (15 credits), or send a fleet. Research costs 40 + 20 × your current level, up to level 5. Technology improves fleet range, speed and combat strength.

Fleet range is 4 + technology hexes, measured across the wrapping map. Travel takes ceil(distance ÷ (2 + technology)) turns. Fleets move after all active humans press Ready. Colony income is then collected. You can Unready until the last commander readies. Building, research and dispatch are immediate confirmed commands; they cannot be undone.

Arriving fleets fight together. Power is ships × (10 + 2 × technology). A force must exceed all opposing power combined to survive. Ties annihilate all forces and leave the star neutral. Surviving ships capture neutral and hostile colonies automatically; friendly fleets reinforce. Research on a colony helps its defending ships; launched fleets retain their launch technology.

Uncharted stars conceal ownership, defenders and income. Exploring or scanning permanently charts their current state; enemy moving fleets remain hidden. The public roster shows readiness, presence and account names. Score is revealed at game end: colonies × 100 + ships × 2 + credits + technology × 25. Highest score wins after turn 40, or the last surviving empire wins earlier. Equal scores share victory.

There is no automatic timer. A host may mark a commander absent for more than 90 seconds ready for one turn. Hostship transfers to a present member after 90 seconds. Rejoin with the same account to resume; rooms expire after 24 hours of inactivity.
