Well, after trying every possible combo I could think of I checked the walkthrough and I can't get past this
So if the rows are A - D and the columns are 1-7 I want to try and light C1, right? But when I click C1 the spark goes to D4.
I've clicked all over and I can't make it make that pattern in the walkthrough.
So I've gone back to periodically clicking randomly hoping I stumble on the solution but no luck so far.
What am I doing wrong?
