I'm a programmer. Many of my current projects focus on areas of research in optimizing modern tetris games

My projects are generally free to use by the public and open source. Github profile

For transparency, (labor aside) my current project costs are ~$5.50 a month for my VPS and ~$5 a year for my domain. I'm happy to continue funding these out of pocket - this is not a request for help funding, just a disclosure for transparency.

sixwi.de

I own sixwi.de and put some projects there.

• SFinder Site
  Web tool for using sfinder. Includes board drawing UI some simple input fields, and a button to call the backend sfinder API. Results are visually renders if applicable. Actively being developed. Most commands are PC related. May add more command types in the future.
  Also available as a discord bot (with more commands). Discord bot is a group project. Best place to get started using the bot might be the PC Gang discord server.
• sixwi.de
  This is where I'm actively developing the original twowi.de puzzle project. Lots of challenging T-Spin puzzles to play here. Compete on the leaderboard! New puzzles are being actively worked on. We also have lst.sixwi.de and allspin.sixwi.de, variants of the original TSpin puzzle site with focus on puzzles maintaining LST or puzzles rewarding allspin.
• Least Blocks Cheese Race Leaderboard
  Originally written by freyhoe, I'm hosting this leaderboard now. Downstacking cheese efficiently is a skill we find valuable, but jstris only has a time-based leaderboard! So we have this third-party resource to track least-blocks as a leaderboard. orz is cool --- Update - seems that after a recent update, jstris does natively support least-blocks cheese race leaderboards, which makes this site redundant. Thus I will probably not put much focus into maintaining this site.
• zztetris.sixwi.de and fumen.sixwi.de
  These are open source on github, but I have them here for the convenient URLs.
• stopwatch.sixwi.de
  Literally a simple stopwatch page. I use it for myself when cooking.
• tetriscom.sixwi.de
  Draedon123's archive of tetris.com gamemodes, being hosted on my domain.
• tes.sixwi.de
  Stream overlay for displaying your Tetra eSports profile stats.

Yukari

Yukari is a Discord bot that I code for and maintain. She has various purposes and public commands - e.g. !tes_profile !tes_lb !tes_rank_cutoffs !tes_lobbies !tetoranks !finesse !fumen
Also used for some custom moderation in some communities. Current server count: 20

Sfinder discord bot

I maintain and host and code new commands for an sfinder discord bot with a couple friends. It contains dozens of commands used to help in tetris research. Very widely used in the tetris research community. Current server count: 100

List of my tetris project sites hosted by github

• cover-visualizer
  Tool for visualizing - in the form of queue lookup - results of sfinder-generated cover.csv files. Homepage has a short demo with a few pre-included files and option to upload custom file. I've also used it to make custom opener guides (e.g. Tsar Cannon and Flattop LST) and setup "solvers" (lookup tables) (e.g. an advanced DPC page). Find more at the repository - each page is in its own folder.
• fumen
  Taken from the original fumen for drawing tetris diagrams and rehosted at fumen.sixwi.de - I've added some QOL features: Grey Out button, Mirror Page button, made dumpstep an editable variable in LocalStorage for more controllable List Views, and made the useful addons load by default ("english.js|onclose.js|greyout.js|mirror.js|listing.js|frame.js|pfcode.js")
• FumenUtil
  This is a tool for manipulating fumen codes with specialized tools. Pretty useful when doing research with sfinder with fumen tools. Too much to describe in-depth within a short summary blurb... Note that Hsterts has forked FumenUtil into Fumenities - it looks nicer and has some improvements and added features. There's still 3 or 4 small things I prefer about my original page though...
• opener_db
  A vast library of tetris openers documented and curated by Eyevy and transformed into a searchable database by me.
• tetriodamcalc
  This is a tool for calculating damage done in tetrio vs S1. And the S2 Tetra League dam calc page
• ttpc
  Hosted the english translated ttpc tutorial (found in four.lol PCO page references) for learning PCO solutions by category. This was a godsend when I was learning PCO.
• ttpc_2
  TTPC but with some QOL changes, faster handling, 180 added, ye
• ttt
  Tetris Trainer Tres-Bien - manually translated to English. Teaches a bunch of useful midgame T-Spin tech, and some useful SRS spins.
• twowide
  Twowide puzzle site, originally set up by garbo and nukeexplosions, now maintained by me. Rush mode is defunct now, without a backend server since github pages is just static. Play on sixwi.de or twowi.de !!! (Actually has backend server. Puzzles there are actively being maintained and updated and new puzzles and features are being added).
• ultra_to_blitz
  Ultra and Blitz are both similar 2 minute game modes where you try to score the most points. But with the blitz level system obfuscating the numbers, how do scores in each mode translate to one another? Use this tool to see how your ultra run would score in blitz.
  (blitz->ultra converter provided as well but is now defunct since osk changed replay format, I haven't updated it since)
• zztetris
  a tetris client that starts with ZZ so you can type "ZZ" into your address bar and have it autocomplete. Hosted at zztetris.sixwi.de
  Actively maintained practice tool.

I have some more private projects that I probably won't share here.
