About Ancient Portal

Ancient Portal looks complicated, but it plays like a single-lane map. Every bloon walks the same spiral first, and you decide where it goes next. That makes the spiral the most valuable real estate on the map: anything that covers it hits every bloon of every round, whichever exit is active.

Pick one exit early and build for it. The left exit is the better choice for short-range damage like Overdrive, Embrittlement or Sauda, because the path is long and twisty and the ruin walls do not matter to towers placed inside them. The right exit suits longer-range towers placed between the spiral and the straight lane, since one tower there can cover both the entry spiral and the exit. Switching mid-round to buy time is possible, but it only helps if both exits have some defence.
