Same as my first version, you can earn sticks to unlock the next level and the challenges get harder as you progress. With the newly added Puzzled Maker, you can now create your own matchstick puzzles and generate a shareable link to stump your friends :)
For example, check out this custom challenge I just created: https://mathstick.github.io/play?q=ktoylsjcnmylbetuinmylielj...
Feel free to share your puzzles below and feedback is welcome.
Your game has a bug which is relatively common in drag-and-drop games. If the viewport is smaller and I drag a match off-screen by accident, it can get stuck to the edge. Then it can become detached in such a way that makes it impossible to recover the match.
Edit: mostly directed at OP, the puzzle maker claimed something like 12 identical solutions for the same puzzle
Also, submit it to https://hnarcade.com :)
I personally found this 'learn-by-doing' approach really helps me understand the patterns before I tackle the harder levels.
