Clever use of indexes w/ the scores and uniq.count to determine whether a pair or tripplet exist. Converting the result from their name to numbers early on made it a bit difficult to follow the steps inside the if-statement since you have to call the score of the number rather than it's name.

Any tips/hints for optimizing the algorithm? Currently passing the sample tests okay, but timing out on the attempt. Thanks!

You've got to be careful of rounding errors. I was stuck on this last test for a while to. I'd recommend putting your values to the log to see where Ruby rounds where you don't want it to.

Thought I was going crazy b/c it looks good. You've got a spelling error. =]

Same thing with Repl.it.
