Ancient Portal is an Advanced map in Bloons TD 6, introduced in version 45.0.

Layout

Ancient Portal has a unique map layout. It has one entrance, but has two different exits depending on which portal is open.

"Realigning" the portal affects what path the bloons come out from after reaching the portal.

A straight path (to the right of the map) is activated by default. It is slightly shorter than the one on the left, but it has no LOS blocker with the entrance, meaning towers can attack both paths. It also has a small lake for water towers near it.

A curved path (to the left of the map) is slightly longer than the one on the right, but there are LOS blockers around it, meaning only elevated towers or "flying" towers can see through them.

For Boss Bloon, it starts spawning near the exit of the bottom right path and moves directly to the bottom left path. Which portal is open does not matter.

Strategy

Ancient Portal is widely seen as the easiest Advanced map, even easier than Cornfield and Off The Coast. This is due to long track length of the top-right to bottom-left path, the flexibility of strategy options from the interchangeable lanes, the bends on the top-right, the wide coverage of the top-right & bottom-right achieved by towers between them, and the additional bends in the bottom-left that allows for even more good placements. Unlike nearly every other Advanced map, Ancient Portal can be beaten with relative ease using general guidelines below.

• Basic Deflation strategies
• Basic Apopalypse strategies
• Basic Half Cash strategies
• Basic Alternate Bloons Rounds strategies
• Basic Impoppable strategies
• Basic CHIMPS strategies

The unique layout of Ancient Portal, with many bends and 2 entirely separated parts of one lane, allows certain strategies (listed below) to excel.

Recommended towers and upgrades

Name	Portrait	Reasoning
Pop and Awe		The many bends on both the top-right and bottom-left is optimal for Pop and Awe. Align the portal to teleport Bloons to the left if using Pop and Awe, as the longer track length and ability to retarget to the bends there enhance Pop and Awe's power further. It deals colossal damage, especially when paired with Striker Jones and Relentless Glue's stun bonuses. Use First Strike Capability or Spike Storm to cover Pop and Awe's weakness against the BAD.
Perma-Spike		The single-lane nature of this map and the long top-right to bottom-left lane aid Perma-Spike greatly. It effectively guarantees victory by tanking the Bloons that towers may leak, in addition to covering the DDT weakness of towers such as Pop and Awe.
Overdrive, The Tack Zone		The abundance of bends on the top-right and bottom-left greatly enhance Overdrive and Tack Zone's power. When placed near a bend, they do solid damage throughout the mid-game and late-game. Use Geraldo, Embrittlement, Berserker Brew, and Primary Training to further maximize their damage.
