Version 100.1 has been released! This is a minor update with multiple bugfixes and crash fixes for everything discovered since version 100.0. Some SEED/BASE reactions have been adjusted slightly and the intro text has been reorganized too. Download at powdertoy.co.uk/Download.html or on Steam.

Version 100.0 has been released! We've fixed a lot of bugs from the beta. There's also some new features, like adding an fps option to settings. Available now on the website, Steam, and Android.
Header for version 100 update - there's some colorful SEED trees on the left, and a V100 logo on the right being eaten by BASE.

A new beta has been released, 100.0! This version is an important-looking milestone, but is a pretty standard release reflecting everything we've changed since last February. This release adds BASE, SEED, stamp search, air sim customization, and more. Download and read a longer changelog at tpt.io
Screenshot of the new beta. SEED has been spread onto a SAND base and grown into several large trees. Some of the trees have pink or lime colored leaves. On one end, there is a CLNE cloning some BASE, which sparkles as it descends and eats various elements, similar to ACID.

Version 99.5 out now - Thank you to everyone who played "Return of the Powder Dinn". All the elements have been restored to their original names and positions with your combined efforts. We'll post the Powder Dinn script to Script Manager later. Progress is kept. Hope you had a fun April Fools!

VERSION 99.4 OUT NOW! Changelog: - After a painfully long wait, the new TPT version has arrived! The game seems to have been abandoned for so long, that it's in a bit of a ... mess. The element labels have all worn off with time. We hope you'll be able to sort it out
Version 99.4's intro text: "Return of the Powder Dinn"

Broke the server and caused error message overload

I guess this doesn't work for open source games. TPT has almost 100 credited developers but is only 6-7MB.
A graph titled Scope of video games according to Hushcrasher Classification System. The Y axis shows Game Size (from 10 MB to 100GB), the X axis shows Credits count (sourced from Mobygames).

The clustered dots on the graph represent 4 distinct scale categories of games - Kei, Midi, AA, AAA. The larger correlation between the size and the credits means larger category of a game.

Edited by me to showcase where TPT falls on the graph, which is far below the chart in an empty ocean. Classications don't apply down here, but it might be implied to still be "Indie" because of how small the game size is.

With Windows 10's EOL approaching, why not try something old. I can confirm the next version of TPT will mark the return of Windows XP support.

TPT 99.3 is out! Since there were so many bugfixes this month, we decided to do another minor release. Some of the bugs are very old, like gravity wall leaks while undoing, or an infinite pressure bug in the corner. Others were new, like elements being missing in certain older saves.

Windows users using the portable version of 99.1 will get a GAME CRASH when updating to 99.2. It is still safe to run the update. The old instance of TPT will bluescreen, and the new instance will launch. Close the old instance of TPT, and then delete the file Powder_upd.exe that it leaves behind.

Another new minor version has been released - TPT 99.2. It fixes some newly-added bugs from TPT 99.1. That means the fps display is back in line with how it was before (no 0.00 FPS while paused), and some bugs on high refresh rate monitors were fixed.

A new minor version of TPT, 99.1, has been released! It fixes some bugs and leftover issues from 99.0, and also some old simulation oddities. Plus, the FPS cap now only applies to the main window, no more rapidly spinning spinners and janky scrolling when you turn off the FPS cap

Oh no, it wasn't just TikTok that was affected!
TPT is open, with the error popup "Sorry, TPT isn't available right now. A law banning The Powder Toy has been enacted in the U.S. Unfortunately, that means you can't use TPT for now."

Happy New Year! In 2024, we added features we talked about and put off since 2014. Next year, my resolution is to do the things I've put off since 2015

A beta for 99.0 has been released! This version adds better search in the save browser, and boosts fps in Fire/Fancy displays by putting rendering into another thread. There's also now in-game credits, a new tools api for creating Lua tools, and various simulation / crash fixes. Download: tpt.io

I see nothing wrong here. That's totally the current logo.
