A puzzle question

I'm either at the end of Returner77 (Part 1) or the beginning of Returner77 (Part 2). It is a beautiful and entertaining game and simple enough that I have completed it it, thus far, without help. HOWEVER; there is now a fairly common puzzle which has been my nemesis since forever. It consists of three blue things in a row on the left side; an empty space in the center; and three red things lined up on the right. The object is to move all the reds to the left and the blues to the right, but I can only move, or jump, one space at a time. It's an old puzzle that I've seen a dozen times and can never complete. Ant idea where on the web there's a picture. I'd look myself, of course, but I have no idea what to call it.. Any help would make me a happy old curmudgeon.

I can't remember what that puzzle is called either, so can't look for a picture of it. Maybe someone else will know.

There are some more folks here with birthday wishes, if you care to see it.

It's a type of peg puzzle.

Thanks for the link. It is now copied, printed, and will be framed over my desk.

That's the spirit!!

The key to solving them is to never put two of the same color next to each other (until they reach the opposite end). Try to make alternate colors across the grid. If you think about it as making alternate colors across the grid, it's easier than trying to get the individual pegs to the opposite side. You can see how the alternating colors work in the solve at https://www.jaapsch.net/puzzles/froghop.htm
