150*3 rep for answers in Factorio (a non-free game)
I'll award at least 150 rep to the first 3 answers in the latest version of vanilla Factorio without using commands, custom scenarios, etc, that:
- It is nontrival: either the shortest answer of all languages has at least 3 bytes, or you have used more combinators (or other structures that compute or generate things; poles and input don't count) than the number of input.
- I can't come up with a better answer in the same version. For code-golf questions, being better means both the grid size and the blueprint string length are smaller. I may not have enough time to play it, so this may take a while.
- Nobody else come up with a better answer while I'm looking at it. And no such bounties were awarded to the same question.
200 rep if it used at least 8 combinators, or 250 rep if it used at least 15.
I'm not sure there is a consensus about the I/O, but I'll try to use a format as close to the original answer as possible.
If there are less than 3 answers satisfying the criteria before Mar 31, 2019, I may (or may not) choose to award to any (previous or later) valid Factorio answers, even without satisfying the criteria. The bounty will be still open if less than 3 bounties are awarded.
