Hallo, HZ here. :) Wow! Can't believe someone showcased my run! I'm truly honoured... thank you so much. :) You quite accurately captured a lot of the non-obvious stuff. To be honest, the whole penny-hoarding setup was chiefly so I would have less to rebuild when I inevitably died and reloaded on Round 74. 5:24 - if you guys are wondering why I abruptly deleted the bottom row of Banana Research Facilities and started packing Sun Gods in that space, it's because *the density of Bloons instantly doubles at Round 120* and the setup from Rounds 102-119 would fail. 6:39 - I really appreciate you calling this out. Seriously, after Round 130 or so, the recording was a much bigger deal than the gameplay to me. And, as a Ph.D. physicist, I really enjoyed your outro. ESA, you will not go to space today! :P The original in all its glory: kzfaq.info/get/bejne/Z7WalsWBtt7GgHk.html Thank you again for the showcase! -HZ

Did you know that in btd4, there was a map with a temple. When you placed down 40 towers you would get a prompt to allow you to purchase a temple for $30,000, and to have all towers sacrificed. This later evolved into the sun temple. (In the expansion pack of corse)

I'm surprised you didnt mention that 250 is actually a special round that isn't random like the freeplay rounds before it. It is designed to kill any players who make it that far. Round 250 contains: 999 BFB's

Monkeys, scuffed graphics, lag, and an explanation of a real rocket that exploded. All key components of the BTD4 experience

8:40 damn the bloons lore is really deep

1:18 The first 3 games actually has upgrade paths, but with 4, Ninja Kiwi decided to go without them for some reason

8:00 As soon as something broke on 255 I immediately recognised the good ol' single byte integer number

I did NOT expect to be suddenly watching a documentary on bit sizes and Aerospace Exploration, but I am totally here for it!

The planes in this version did not have any footprint so you could place as many of them on the map as possible without running out of room. But it would mean you could not select some of them as they would overlap each other

It's insane how since BTD4 each bloons game has had seemingly exponentially more content. Could you even imagine a BTD7? Considering BTD6 is still getting new content, i can't, but it's insane looking back and seeing how far it has come

This actually just gave me the wave of nostalgia of when I found out about the highest round of BO3 zombies being 255 as well, was not expecting that

Great video but the part at the end is incorrect - there is no byte data type in flash and definitely not an unsigned one. The round is stored in an int(more specifically, 2 ints which average out to the actual number for anti-cheat reasons). There are 250 rounds because the rounds are hard coded into a 250 element array, after that the enter frame event is never able to complete because of exceptions(you can see them in a debug flash player). I don't know why it ended at 255 specifically for you but I was able to start at 249 and get to 260. Also - the game was made in 2009 and 3 bytes of storage relative to the entire game is not going to make a difference in performance considering that 4gb ram was fairly common then.

Another thing you can do is infinitely stack planes. However it might be more lag intensive given how many projectiles get on the screen at once later on

I remember I had BTD4 on my phone, and I basically had the entire screen covered in towers and I would just let me phone sit and run automatically because of how many towers I had. Since it was an iPhone 4S at the time, it eventually got to the point where 1 level would take 15 minutes with all the lag lol

Sucks hearing BTD 4 is now old school, grew up playing these games. I hate getting older 😭

I miss abusing hotkys in this, going to set down roadspikes but clicking and hitting a tower hotkey at the same time letting you place towers on roads, or essentially bypassing large footprints by using smaller towers and then swapping as you click. Same could be done when upgrading then clicking a tower down at the same time, it gains that new tier of upgrading instead of being a fresh tower.

It's real funny, my dad used to do this casually when it came out. He'd just leave it running to get groceries or watch TV, and come back to the rounds still not being finished. If i remember correctly, his strat included way too many fully upgraded Mortars.

Crazy to see that BTD4 has a limit of 250 rounds! Strangely enough, the limit was removed in the mobile version of BTD4, so it technically has infinite rounds, despite having mass slowdown in rounds 76 and beyond with the loads of BFBs rolling in.

old arcade games trying to get to lvl 255: Impossible please just stop playing BTD4: Here is your Medal: NULL

what a great quality for a video of our past, thank you for this high quality and entertaining videos Mackan. you're work is insane, thank you for your service to the commuinty.

Mackan is doing things that I didnt even thought of

I’ve been watching from your first video and I love this type of content, I wish you good luck and hope you keep going. Maybe someday you can be on the level of SJB or ISAB edit: thank you for the highlight

Loved the video and it was really interesting with the "NULL" difficulty, challenge Idea: round ??? with only using the circles and centre structure of the map "X factor"

It's crazy how far this series has came, i remember playing Bloons, and the first BTD. Kinda dawned on me recently just how popular it is now, blew my mind.

I played this game so much, I remember spending so much time beating all the maps and talking to all my friends, though back then I didn't really go into freeplay

It’s funny how nearing the end of this video it almost feels like a vsauce video with the music, and education at play.

I love that you sed the technical explaination without hand waving it

did not expect the video to turn into a deep explanation of computing and aerospace disasters; but nice

Man i remember this game… one of my childhood games. Good memories

I really do wonder now, what about speedruns trying to get to null round as fast as possible. Of course we'd need some internal game clock reference to not make it hardware based, but basically it would be an interesting challenge of placement and minimising lag.

I'd love to see more content like this

Bro how are your video ideas for late game so crazy and how are your videos so interesting lol

It's kinda easy if you're experienced to never die tbh. I remember once placing a sungod in every single possible place I could like he did while leaving some farms and also a shi ton of those airplanes as they could be placed infinently lmao

this is one of the multiple examples of the byte count system, another famous case is the level 256 in Pac-Man, when half of the map disappears

That is some crazy dedication to set an alarm and stand up every night.. just crazy

"It's nice to come back to these old school games and REALLY finish them." Amen.

Fun fact: If you hover your mouse in water with the buccaneer, right click, and place it somewhere (That isn't on a tower) you can place it anywhere you want.

idea: how far can you get using only the prime number tiles on the map one two tree, great video btw

I always wanted to know what’s after Round 250, thanks!

W video bro

This limit doesn’t seem to exist in Apopalypse mode, since I made it to round 257 before selling everything and ending the game

7:58 what happens when we click "keep playing in Freeplay Mode"? Does it just start over again with no monkeys and default cash as we can see in the background here?

You can easily get in the hundreds of rounds but I never could figure out how high exactly because the rounds take SO LONG past round 100

This video is so creative

Cool! I wish you were the one who played this though, I bet your video wouldn't have had the aspect ratio crushed like it did

Did not expect to be told on the incident of that rocket that big bird declined

I never thought that an episode of Bloons tower defense would go into rockets exploding

We had different upgrade paths back in btd1, but they were removed by the time 4 hit but brought back for 5.

I'd love to see this but with BTD5 since in that game you can get into the thousands of round. I myself have even gotten to Round 1.500 with little experience

2:58 I prefer the sounds in Older BTD games than in 6. It just sounds punchier

I feel like you can get quite far, considering the planes have 0 footprint.

I remember a run I had back in the day where I used mainly Laser Cannon dartling gunners after it was released, got to round 140ish, around there

in other words every map has a secret medal in btd4. now the question would be for how many maps you can gain it

i tried doing late game in btd4 and spammed the entire map with sun avatars but there seemed to be a pierce problem, a lot of the monkeys were getting 0 pops and died around r80

Love the documentary-style content! 10/10 video ❤️

my friend and i once made it to about round 200 on btd4 ios on my old ipod touch. we could definitely have gone longer, but as you said the lag was unreal and rounds took an agonizing amount of time, and you couldn't have more than one saved game at the time. btd4 ios let you save in freeplay, but eventually i just wanted to start a new game.

Imagine someone skipping to the end just to see what round he got to just to see 8:40 and not knowing what is going on.

Wow nice video

As a kid I really wanted to pass round 250 but I couldn't even reach 90

could you please do this for btd5 next? id love to see it id be really cool

Crazy to think I had a single apocalypse run going for 3 weeks on my ipod touch, couldn’t know what round I was on because I only checked in the morning & evening and one day it crashed I guess

What a great nostalgia trip

I love this game the first Bloons game I played was btd4

for your next vid could you see the highest round you can get to on bloody puddles apopalypse? could be very interesting with how the map works

This is *basically* the Bloons equivalent of those Arcade Kill Screens.

the music choice here feels like a 2013 creepy pasta video haha

ok, im starting to love this video only because of the dramatic songs

Btd4: can only handle up to round 255 Btd6: can handle up to round 609

I used to play this and quit because I couldn’t lose. Just spammed sun gods. I remember being able to play my own music in game. Like my own jukebox. Never had a problem with later rounds, but played it early on so who knows.

1:18 there actually were upgrade paths before 4, they just removed them in 4.

Pointing at the screen and jumping up and down and going "ooh ooh ohh!" 'cause I heard the number 255 (thats a power of two minus one)

You should cover the mobile version as the mobile version of btd4 does not have the round 255 limit

I remember getting to a high enough round in 4 that it was basically just painful white nose every round

The mobile version might be different as i remember getting to round 240 with only toad spikes before

Dang didn't realize about the rocket that's crazy

I played this game in like third grade omg the nostalgia.

1:17 Small clarification, we did have upgrade paths. In earlier games. They were removed for 4. Also, it wasn't universally praised as "the best bloons td game by far".

"Hmm yes today I will watch silly bloon video" "-and that's how the aryan 5 exploded"

You should try bloons tf 5 its pretty fun and theres not that Much lag

0:14 I actually remember it coming out

I remember playing btd4 on my grandma's ipad in like 2012, when I was but a wee lass. Good times

The best content! I want to see btd5 - flash version

What variable type is the BTD6 round number? If they just slapped an int in there I'll be disappointed, I really hope it's optimised with something like unsigned short.

After round 250an text box appears that it was bugged but however when you click ok noting for the rest of the rounds

In the mobile version, you can go significantly further. I don't know how much further, because I got bored before I got even close to losing, but a map filled with sun gods, buffed by villages, a few artic winds to slow down bloon innards, on daisy chain seems to be optimal. Ive done some testing with moab maulers and monkey apprentices, and there are situations where maulers might be superior. There might be a limit to how many times a bloon could be hit in a frame, and maulers seem to have a higher pierce limit. Monkey apprentices seem good for guarding against rouge bloons about to escape. It's possible that some number of maulers and apprentices might possibly replace some number of sun gods in an optimal setup. Another powerful tower is the ace, which while significantly weaker than other options, takes up no space on the map, leading to a theoretical infinite number on the map. It's probably not worth the lag, though.

nice video mackan

what about bloons td 5? after the hangar ship glitch got patched i'm pretty sure after round 1000 is impossible / very very hard. I made it to round 1000 and had to constantly use the super monkey special power to even survive. As shown in my video :)

I wonder if the same is possible with the mobile version of the game. It might have different effects, as they didn't just port the original flash version, they completely made a better version than the flash original. So it might function differently once you get to the null part.

I went away from phone for a while and when i came back i see monkey game guy talking about rockets lmao

mark my words, this is going to blow up huge!

0:57 I didnt know BFB was added in the 4th game Is that a bfdi reference

My highest wave I've ever gotten was round 164 I just spamed Sun super monkeys and bomb towers

You can just do impoppable mode and that makes the rounds auto start

I wonder if it's the same case for the mobile and DS ports, or if you can get further than round 255 in those versions

Bro why this like a creepypasta story😂

Congrats on having this be your 69th (nice) video

yo that's hype nah, nah, bloons td 4 sfx are pure nostalgia, and thus of the highest quality >=( wait, so what does continuing on freeplay after clearing null do? just bring you back to round 1?

i played the ds version of this game and it looked a lot diffrent to the pc version. You could also place towers overlappen half their textures, i think you could get further on the ds

we won war agains bloons now we can go back home

Legends says he didn’t use auto clicker to start rounds
