Hey Product Hunt, I’m Lena, and I built Nurikabe Islands after falling in love with this lesser known Japanese logic puzzle and realizing there was not a mobile version that felt simple and relaxing. A lot of puzzle apps add pressure with countdowns, interruptions, and clutter. I wanted the opposite: clean design, thoughtful puzzles, and the satisfaction of pure logic. What makes it different: • No countdown pressure. We only show your solve time after you finish • Minimalist themes that stay out of the way • Works completely offline • Hints are there when you need them, without blocking progress • Focused on solving, not on keeping you hooked If you enjoy Sudoku or nonograms and want a fresh logic challenge, I’d love your feedback. The app is free to download on iOS. What’s your go to logic puzzle when you want to unwind?
