Puzzle #664 - 24HPC Ripple Effect

I also contributed several puzzles to the Puzzlers Club rounds at the 2024 24 Hour Puzzle Championship this year. We authored two rounds, each with 24 puzzles. The first round had one puzzle themed on each Greek letter, while the second round was a double zodiac (signs and animals).

As construction was wrapping up there were a few missing Greek letters. None of the puzzles so far used the grid shape for the theme, and Ripple Effect is always a fun type to do on irregular grids. This puzzle ended up being only worth 25 points which is a bit lower than I would have expected, but I guess most of the solve path is pretty straightforward, and even though it's "10x10" there is a lot of empty space.
