User blog:Dinner111/Quad Spiked Mines setup

The Quadruple Spiked Mines setup is an effective defensive setup because it covers the end of a track with tons of spiked mines. Sure, it is more effective to have more Spiked Mines Factories, but 4 will do fine up until the bloons start speeding up, & by then, most players would've bought several maxed Temples & MOAB Cripplers.
