Hey I have never hosted a shuffle before, mostly because there are no ideas that I can think of.
However, I helvellyn came up with an idea to stop a solve! I love it!!
The goal: To stop the ball from reaching a goal
You may add/delete only two pieces per edit.
Solves must not solve.
Edits must self-solve.
Edits must be possible to stop from solving. (duh)
Make the level doable please!
In props to helvellyn for the idea, his level will be the starting level! Go nuts
Please let me know of anything that is unclear or wrong!
