OneWay vs ECHO

OneWay is a clean, satisfying puzzle game where your goal is simple: connect the entrance to the exit using tile pieces. Place tiles on the grid to build a continuous path from IN to OUT. Every tile must be used — no extras, no shortcuts. As you progress through 100 hand-crafted stages across 5 zones, new mechanics are introduced one by one: • CLASSIC — Learn the basics. Place tiles to form a clean path. • FAKE — Extra tiles are added to mislead you. Only the right ones form the path. • BRIDGE — Paths can cross. Figure out which tile goes over which. • PORTAL — Teleport between two points on the grid. The path continues on the other side. • MULTI-LINE — Two separate paths. Both must be completed at the same time. After clearing all 100 stages, Infinite Mode unlocks — endless puzzles with randomized zones and grid sizes. Simple rules. Deep thinking. OneWay.
