Ok. I give up. What are these?#2: Ken Mikolas (kennymik) on Jan 16, 2020
Dashboard icons from your car!#3: Nancy Anthony (nancya) on Jan 16, 2020 [SPOILER]
Check oil level#4: Teresa K (fasstar) on Jan 16, 2020
These are great fun to solve, Brian. You made my day. (✬‿✬)#5: Brian Bellis (mootpoint) on Jan 16, 2020
Deal with it right away. You could ruin your engine.#6: Andrew Schultz (blurglecruncheon) on Jan 17, 2020 [HINT]
I was going to use edge logic on R13 (I was spamming the L key for hints until the site stopped giving one) but then noticed r12's 1-2-1 could place a dot in the r13, with c10 being a dot and c11 being a black square. That makes r13c13 a dot, which cancels out the same as edge logic would have.#7: Kristen Vognild (kristen) on Jan 17, 2020 [SPOILER]
So if anyone is wondering why this is line logic, there it is.
"Change the oil, you monster!"#8: Joe (infrapinklizzard) on Jan 18, 2020 [HINT]
Andrew, I could not follow your explanation. c13r13 is not a dot, it is black.#9: Joe (infrapinklizzard) on Jan 18, 2020 [SPOILER]
Here is my line logic:
After easy LL,
The black pixel in r12c16 must be part of the 2 or the right 1 in r12. Either way r12c18 must be dotted.
easy LL to finish
This one is not to change the oil. It is telling you that there is a lack of oil pressure (usually due to not enough oil). That means that your engine is grinding metal-on-metal. Not good if you want it to keep running for any amount of time.#10: Kristen Vognild (kristen) on Jan 19, 2020 [SPOILER]
Check your oil level. If it's low, add enough to bring it back to normal (don't add too much - that causes its own problems.) If the oil level is normal and this light is on, get it towed to a garage. The money you might save by driving it yourself is not worth the risk of seizing the engine.
Maybe so, but if it's this low, you probably DO need to change it! If you take it to a garage, one would hope they check for leaks. :)
