koushi - Word Fit Puzzles

Relaxing Word Puzzle & Logic Game — Experience Visual Silence with koushi.

Officially Teacher Approved: koushi brings the classic grid fill puzzle to your smartphone and tablet in a completely new, soothing dimension. Designed with an uncompromising focus on reducing sensory overload, koushi offers a relaxing word game experience for clever players of all ages. It's a fill-in puzzle: A blend of word search and crossword puzzle — but without the noise and without the stress. While other logic games disrupt your concentration with flashing banners, loud pop-ups, and artificial time pressure, koushi takes a completely different path.

Award-Winning & Designed for Pure Focus (especially suitable for ADHD, Autism & AuDHD)
Awarded the "Teacher Approved" badge by Google (ages 9+), the game gently improves vocabulary and concentration. We created koushi as a low-stimulus, minimalist puzzle space. It's ideal for people on the autism spectrum, with ADHD and AuDHD, and for anyone who just wants to unwind after work or school. There is absolutely no haptic feedback, no frantic animations, and no glaring red error messages. "Visual Silence" means a distraction-free interface with clear typography and an eye-friendly Dark Mode. Whether you're looking for a break from daily sensory overload or just want to train your brain without getting tired eyes — this is your digital retreat.
