#Built on What We Love
I'm grateful for this community. Sudoku Launchpad is my way of giving back.
SudokuPad
It (almost) goes without saying that this community would not be what it is, and Sudoku Launchpad would not exist, without the heroic efforts of a single engineer - our favorite engineer - Sven Neumann. He works tirelessly to give us a free platform for enjoying a seamless puzzling experience on SudokuPad, and this application is built on top of that solid foundation.
Thank you, Sven, for all that you do for this community. Visit his Patreon and show him some love!
Puzzle Constructors
I have heard it said that these variant sudoku puzzles all already exist, the constructors are merely discovering them. Even so, I will forever be in awe of their ingenuity, and grateful for the joy each one brings to my life.
Sudoku Launchpad is one small way to give these setters and their craft more of the spotlight they deserve.
Cracking The Cryptic
Like many of you, I stumbled across the Cracking The Cryptic YouTube channel during the pandemic and have been hooked ever since. After years of learning from Simon's patient, joyful teachings and Mark's world-class solves, I now enjoy a nightly routine of watching their videos after attempting the solves myself. When I realized I could use Sven's replay data to render our own solves alongside their videos, I knew this was my way to finally give back to this generous community.
There's a wonderful feeling watching your replay side-by-side with their solves and seeing the same deduction land at the exact same moment. That's a joy I want everyone to experience on Sudoku Launchpad.
Community Driven
I build apps like this because I want to use them myself, but the ultimate joy comes from all of you using it. Your feedback and ideas directly influence what gets built next, so reach out at hello@sudokulaunchpad.com and let's build this thing together!
