List of rounds in BTD6: Difference between revisions

Rounds after 140 are randomly generated, but there are a few rounds with restrictions on what can be spawned Round 200 will only spawn two Fortified BADs. Round 163 will only spawn Ceramics, Fortified ceramics and Fortified Leads as a reference to round 63. Round 263 will only spawn MOABs, Fortified MOABs, and Fortified DDTs.

Once the player reaches round 500, the health scaling reaches its maximum (+500% per round). At round 1636, all possible Bloon groups can spawn at random will spawn every round. The only random thing is the order which they spawn, until round 9999.

==== Pushing the limits ====

At this point, these rounds are impossible to reach without cheating because Bloons move too fast to react. Round 10,000 only has 200 fortified BADs, and the next five are specifically for testing. Round 10,001 has 9999 Fortified ceramics, round 10,002 has 100 MOABs, round 10,003 has 100 BFBs, round 10,004 has 100 ZOMGs, and round 10,005 has 100 DDTs.

From round 10,006 onward, only 200 fortified BADs spawn every round, until round 536,927. Starting at round 536,928, no Bloons spawn at all, up to round 1,073,798, in this case the game will simply consider the round won instantly and move to the next one. Next up is a 1,073,742-round cycle between a round with 200 fortified BADs and other with no Bloons, lasting until round 10,133,701.

At round 10,133,702 and beyond, nothing will spawn at all, and the round number continues increasing until reaching the 32-bit signed integer limit of 2,147,483,647 where it overflows and jumps to −2,147,483,648, and then continues increasing. After a lot of waiting, eventually the round counter will loop back around to round 0, and then back to round 1 where the cycle starts again. This means round 0 is the final round that can theoretically be reached.
