About

Transversal

Features
Read full description

TRANSVERSAL is a minimalist one dimentional (1D) perception puzzle game built around one simple idea: a line can hide more than it shows. Each level presents a clean, monochrome figure—often ambiguous at first glance. Your job is to spot the real shape, trust your brain’s pattern recognition, and type the answer. No clutter. No distractions. Just you, the line, and that moment when it suddenly clicks. Why you’ll like it: Minimalist design: simple, high-contrast visuals with a clean, flat look Fast, satisfying puzzles: short rounds that feel great in quick sessions Portrait-first gameplay: designed for vertical mobile use and limited screen space Keyboard-friendly: the game is built around quick typing and instant feedback You saw beyond the line. Now keep going.
