“ | So this is the equation playground? | ” |
“ | Huh? | ” |
The Equation Playground is where Algebralians live and play in. It first appeared in "X Finds Out His Value", and would later on become a location in Battle for Dream Island: The Power of Two, with it first appearing in "Out Of The Blue" and playing a role in subsequent episodes. It also appears in non-canon material such as "The Number Playground Chronicle!", "Lo-Fi Beats to Yoyle To", and the subscriber specials starting in "Thanks for 700,000 subscribers!".
In the post-credit scene of "Bottle For Dream Island", it was later revealed that the playground was in fact connected to the EXIT. It is further revealed that all of the inhabitants of the playground had left it, with the sole exception of Six.
Appearances[]
In "X Finds Out His Value", it was shown for the whole video when Four and X were in the equation playground.
In "Out Of The Blue", Pencil, David, and Bracelety find a door in Four's internal school that leads to the playground. Six is also seen at that moment. This moment makes this location, and maybe even the sub count specials canon to BFDI, although the latter is unlikely, since Four appeared in the subscriber specials even when he was inside The Desert.
"Seasonal Shift" shows what is presumably the "Math Earth" on which the playground is located. This planet is below Earth, which is knocked into it by Anchor. The playground itself appears in the stinger, which shows Barf Bag, Bomby, Bell and Needle passing through a door in One's Field, and entering the Equation Playground. It could mean that the playground and One's Dimension are in some way connected. On older version of the equation playground from "X Finds Out His Value" also appeared in the episode, signifying that it is canon to the main BFDI timeline.
In "Bottle For Dream Island", the Equation Playground is shown again. It is also revealed Six is the only algebralian in the Playground. This may have a connection to One, as they said "She was meant to be gone!" It is unclear whether the other residents left by choice, were taken, or other reasons. However, Nine was presumably in the playground at the time of "The Escape from Four", as they were shown near it in "Seasonal Shift". Four and X are known to have left willingly to start BFB, and Two to start TPOT, so it is possible that the others also left willingly.
Subscriber Specials[]
"Thanks for 700,000 subscribers!"[]
Four climbed a mountain to go to the Equation Playground. There, Four announced that Seven could take Six's place on the subscribe count.
"Thanks for 800,000 subscribers!"[]
Seven, Four, Eight, Nine and X helped Six get back on the ground. Then, Six kicked Seven so that Eight could take Seven's place on the subscribe count.
"Thanks for 900,000 subscribers!"[]
Nine and Six mined rocks out of a mountain to use on X's Stone-To-Boot-O-Tron, which could produce a boot to kick Eight from his place on the subscribe count.
"Thanks for 1,000,000 subscribers![]
Five, Nine, Seven, Six and X competed in Battle for Permission to Meet 10 hosted by Four, which was deemed unnecessary after Eight brought Ten from their even-numbers-club for the subscribe count.
"Thanks for 1,500,000 Subscribers!"[]
Nine and Six combined, due to Fifteen refusing to take her place in the subscriber count. Nine and Six split up after some bickering, which lead to even more arguing about the subscribe count. The Zeros' became tired of it, replacing the subscribe count with a whiteboard.
"Thanks for 2,000,000 Subscribers!"[]
Fourteen splits himself into two Sevens, causing mayhem. As payback, Five, Six, Eight and Nine trick Fourteen into trespassing Fifteen's shack.
"Thanks for 2,763,000 Subscribers!"[]
Two, Five, Six, Seven, Eight and the zero's are in the Equation Playground searching for a tape that has instructions to defeat 2763, the most powerful number.

Current Residents[]
Former Residents[]
Canonically, every Algebralien besides Six has left the Playground by the time of Bottle For Dream Island, making them all former residents.
Since X Finds Out His Value is canon, Five, Seven, and Eight are also former residents.

Trivia[]
- According to "X Finds Out His Value", there is at least one tree, one bench, and several equation see-saws there.
- Additionally, in "Thanks for 700,000 subscribers!", it is shown that there is also at least one swingset with omegas for bases and a minesweeper.
- As shown in "Thanks for 700,000 subscribers!", it is located on the Earth.
- However, in "Seasonal Shift," a math-themed planet can be seen, which would imply the Equation Playground is canonically on that planet, and the Equation Playground is only on Earth in the Algebralian universe.
- A map of the Equation Playground can be seen in the The Number Playground Chronicle! .
- As seen in "Out Of The Blue" and "Seasonal Shift", both Four and One have entrances to the playground.
- It could also mean that Two and their pocket dimension could also have an entrance into the playground.
- Two can be seen in both areas, the Equation Playground and the Grasslands, the place where they host TPOT.
- This could further lead into the theory that the Subscriber Specials and the main BFDI world take place in separate realities.
