Positioning first: a defense-themed quick-play board where every round is a small deployment puzzle - place domes, watch the wave, collect per intercept.
The board shows several incoming lanes. Before each wave you position your domes - more domes or upgraded coverage cost more per round but intercept more lanes. When the wave fires, every lane covered by a dome pays its posted intercept value; uncovered lanes that carried a missile close the round. Rounds resolve in seconds, which is why Iron Dome sits in the quick-play cards corner: it has the decision count of a card game and the pace of an arcade.
Because all coverage costs and intercept values post in advance, the honest entry is the Iron Dome Demo - twenty free waves tell you which deployment habit actually fits your budget before real stakes move.
