Operation Lightning
A scouting board in the fog: one Sharp Eye uncovers one cell of a 5×6 grid. Somewhere on it sits a vault — dig it out whole, then click it up to three times for a rarity upgrade, since the richer tier draws from a better pool. A missile clears its entire row AND column at once and chains into other missiles, which is why layers that carry one cost less than layers that do not. Claim the vault and a parachute takes its place, leading to the next layer.
Campaign bosses drop 20 “Sharp Eyes” at a time, up to 120 a day — the only free source of scouting there is.
Scout calculator
The run lasts 20 days. Campaign bosses hand over up to 120 “Sharp Eyes” a day for free — this works out how many more you would have to buy.
Layer 200 takes 2,515 farmed “Sharp Eyes” plus 263 bought — that is 26,300 diamonds and no real money.
Expectations, not a roll: a layer's cost is simulated over its layout, and a real run will differ.
What the fog hides
One scout uncovers one cell. The missile is the only thing that opens cells for free: it clears its whole row and column and sets off any missile it catches.
Supply crate
Vaults
A vault has to be dug out whole before it can be clicked up to three times — the attempts land at 95% / 70% / 30%. Each success raises its rarity a step, and the reward pool with it.
Layers of the cycle
The 25-layer cycle repeats until the scouts run out. A layer that carries a missile costs about 12.9 scouts, one without about 15.5 — which is why a cycle average would be misleading.
Spend milestones
Counts every “Sharp Eyes” spent over the run, farmed or bought alike.
Lightning Battle Pass
Nodes unlock on “Sharp Eyes” spent, the last one at 700. The paid branch costs $4.99.
