Conquest

How to play: the world is twenty-one territories in five regions, dealt between you and two rival commanders. A turn comes in three parts. Reinforce — you collect a third of the territories you hold (never fewer than three), plus the bonus for every region you hold whole, plus two more if you took ground last turn; click your own territories to place them one at a time. Attack — click a territory of yours holding at least two armies, then a neighbour that isn't yours. The attacker throws a die for each army beyond the first, up to three; the defender throws one for each army, up to two. The highest of each side is compared, then the next, and the loser of each pair loses an army — ties go to the defender, which is what makes attacking uphill expensive. Empty the defender and the territory is yours: everything but a single garrison marches in, and you can carry on attacking from there. Fortify — once per turn, move armies from one of your territories into a neighbouring one, leaving one behind, then the turn passes. Take every territory on the map to win. If the war is still running after sixty rounds, the largest empire takes it.
