Round 13
Round 13 in BTD6: 50 Blue and 23 Green Bloons, 169 RBE. The second long round of the game, with cash and defence tips.
Guide
Round 13 is a long, steady round of 73 bloons. A stream of 50 Blue Bloons runs for 30 seconds, and 23 greens are mixed into it over the same period. At 169 RBE it is the heaviest round since round 10, and because the two groups overlap, the track carries more bloons at once than in any earlier round.
Bloons in round 13
- 50 × Blue Bloon (0.0s–30.0s)
- 23 × Green Bloon (2.2s–32.2s)
Total: 73 bloons worth 169 RBE. Popping everything pays $169, plus the $113 end-of-round bonus.
How to beat round 13
This round checks that your defence can keep up for half a minute without breaks.
- Sustained attack speed beats burst damage here. Upgrades such as Quick Shots on a Dart Monkey or Faster Shooting on a Tack Shooter pay off.
- Spread towers along the path so every bloon has to pass two of them.
- If you are farming on Easy or Medium, the hero plus one upgraded tower is still enough.
The round pays well thanks to the number of bloons, so it is a good time to buy your next big upgrade.
Alternate Bloons Rounds
The ABR version keeps the 50 blues but swaps the greens for 18 Yellow Bloons. Yellows are fast, so the mix of a long blue stream and quick yellows can overwhelm slow single-target towers.
- 50 × Blue Bloon (0.0s–30.0s)
- 18 × Yellow Bloon (2.2s–32.2s)
ABR total: 68 bloons, 172 RBE.
