I really need to remember this exists.

So fancy! 👌

Real subtle how it handles the last frame.

nice solution though

can't read(

You are welcome, glad you learn something through it ;-)

I wasn’t familiar with DFS algorithms, until now :) I'm fairly algo ignorant still, but a little less so because of you. Thanks for taking the time to put the logic into words so well.

You were right about documentation so here is a fork of this solution, explaining it step-by-step.

Some actual variable names or comments would help people understand what's happening here and why.

He uses for i in range(10), so the final roll is only added as rolls[1] from strike or rolls[0] from spare.

Amazing.
Can somebody explain how this excludes the final three from giving bonus points for Xs or /s?
If the final roll was a X, wouldnt it run: score += frame + rolls[0] + rolls[1], which would cause an out of range error?

You know, magic ¯_(ツ)_/¯

how did six people use the same names and stuff and then get best practices?
