Easy as ABC (Irregular) by Serkan Yürekli
or solve online (using our beta test of Penpa-Edit tools; use tab to alternate between a letter entry mode and a shading mode. CAPS LOCK is recommended for letter entry.)
Theme: Easy as
Author/Opus: This is the 379th puzzle from our managing editor Serkan Yürekli.
Rules: Fill some empty cells with the letters E, A, S, Y so that each row, column, and bold region contains each letter exactly once. Some cells will remain blank. The letters outside the grid indicate the first letter seen from that direction.
Difficulty: 2 stars
Time Standards (highlight to view): Grandmaster = 1:15, Master = 2:30, Expert = 5:00
Solution: PDF and solving video.

Impressive construction, especially with region symmetry! I think I like the irregular variant more than the normal Easy As type, but I probably need to do more puzzles in the vanilla version to become comfortable with the logic.
A note on penpa — not sure if I missed a setting, but I had to use caps lock to enter uppercase letters — shift-E just put a little e in the corner.
Correct that CAPS LOCK is a good way to interact here; I’ll add a note to these posts.
