Stop them reaching the exit
Enemies walk the lane from the entrance to the red exit. Anything that
reaches the exit is a leak. Fewest leaks wins — zero
is a clean sheet.
Spend your gold on the right towers
Each day offers a different handful of towers and never enough gold for
all of them. Check Incoming first: armored enemies
shrug off small hits, swarms overwhelm single-target towers, and
insulated ones ignore frost entirely.
Three runs, then post your best
You get three attempts at the same board. Ties break on
gold left over, then ground held —
the share of the lane you denied them, so killing things early scores
higher. Everyone plays the same board each day.
