Robot players fill in spaces in Duel and Trinity games. They start with the usual stuff in their home province, just like human players; but follow predictable automatic rules every turn:
- From the last province it captured (or its home on Turn 1), each robot player will attack one adjacent prov that it does not already own at the start of the turn. It will attack it with ALL the armies it has in that last-taken prov, but will make only one attack. Thus, each robot player has a "head" which attacks forward, one province per turn, until stopped.
- If there is more than one possible adjacent prov to choose from, it will first TRY to avoid attacking another robot player - robots are all "semi-allied". It will first look for THE LOWEST ADJACENT PROV NUMBER that is either human or neutral, and ignore adjacent provs that belong to other robots at the start of that turn. But if there is no human or neutral adjacent prov to attack, then it will attack an adjacent robot, once again choosing the lowest prov number of the adjacent provinces. The only exception to this is if headhunting would not allow the attack, in which case the next lowest numbered province will be chosen.
- This means that robot players TRY to avoid each other, but will attack each other if there is no alternative human or neutral province to attack. Also, two robot players may well go for the SAME province on the same turn, and clash there, since they only take account of who owns what at the START of the turn. These collisions are worth keeping an eye open for, since at least one robot must become headless and inactive after such a head-on collision.
- A robot player can paste itself into a corner, and have nothing to attack next turn ... until perhaps "released" by losing a prov adjacent to its "head".
- The robot player changes every captured province's (and the home province on turn 1) aim over to producing missiles. It never fires them, but it produces them and they are there to be captured.
- When it captures a province, it orders 2 transforms of 48 population into armies in the captured prov, and also orders 5 armies back from the captured prov to the prov it attacked it from.
- Robot players should, in general, run out of steam as the game progresses, since they never replenish their Effectiveness. A win by a robot player is impossible.
