HTwins.net (Huang Twins.net) is a website created by Michael and Cary Huang, the creators of Battle for Dream Island. It contains multiple games and features, including GTTTATINT (Get To The Top Although There Is No Top!), BFDIA 5b, Racing Extreme, Tidepool, Scale of the Universe 2, and other content, such as their early animations (eg. X Finds Out His Value) that were made before they started making Battle for Dream Island. The website was temporarily down for a few weeks in 2018, but Cary was able to get it back up on August of the same year.
These are the interactivites/games that used science and math.
Time Minesweeper is a game on the website that allows players to play Minesweeper and its many variants. Upon entering, players have to type their name.
Carelics is a collection of old HTwins games, in which they have been all relocated under this one title. The multiple games that can be found and played on Carelics are Icy Mountain, Z-Time, Chompster, Elemental, Elemental 2, and Metasquares.
Tidepool is a game inspired by the beginning stage of Spore. You start off as a small creature in a massive terrain with many different creatures. The objective is to eat the creatures that are smaller than you, while also avoiding the creatures which are still bigger than you or else you will shrink. There are a total of 100 levels and 4 creature sets.
The Scale of the Universe
The Scale of the Universe is an interactivity that shows objects of various sizes from quantum foam to the universe. There is a slider on the bottom to navigate to the objects of different sizes. The sizes range from 1×10^-35 to 9.3×10^26 meters. There is also a "wrong" version which has randomly generated sizes for all measurements and items.
The Scale of the Universe 2
The Scale of the Universe 2 is a sequel to The Scale of the Universe. It has more objects than the previous version, has more languages, and there are info boxes for each object that appear when the object is clicked. The interactivity also has new graphics, a larger screen, and buttons for toggling the sound and music and changing the language. This interactivity was once featured on two Vsauce videos.
Edit the Text
Edit the Text, as seen from its name, was a site made for editing a certain page with something that a person might want to edit.
Everyone was able to edit any page in Edit the Text, with the link htwins.net/edit, and the editors allowed users to add anything they wanted, like a paragraph or other things. This can be done by adding a string of up to 4059 characters after the "/edit" with another slash, like htwins.net/edit/test, to go to the page test, and they could have edited from there. (This already has been stated in the basic /edit paragraph) It was removed when the website went back up in August 2018, after a few years of service, which had a lot of things going on in Edit the Text in it's timeline.
