Undyra – Wave Logic

Predict the first grid cell two waves can reach in the same number of steps in Undyra. Read obstacles, compare routes and test your spatial reasoning offline, without advertisements or a user account. Undyra is a fast and atmospheric spatial puzzle game. Two colored sources release waves across a changing grid. Once you choose, both waves travel across the board and reveal whether your prediction was correct. EASY TO LEARN, CHALLENGING TO MASTER Each wave moves one cell per step and must find its way around blocked tiles. The first shared cell that both waves can reach in the same number of steps is the correct answer. The rules are simple, but every new board creates a fresh spatial challenge. INCREASING DIFFICULTY The playing field quickly expands as you progress. More obstacles create longer and less obvious routes, additional visual elements test your concentration, and the available decision time gradually decreases. No two rounds feel exactly the same. BUILD YOUR STREAK Correct predictions earn points. Make several correct choices in a row to build a streak and increase your score. Fast decisions receive an additional time bonus, while three lives give you the chance to recover from mistakes. Try to beat your locally stored high score and enjoy the satisfaction of one more round. PRISM FLOW EXPANSION The optional Prism Flow expansion introduces a complete additional mode. A prism accelerates waves along selected paths, creating new route combinations and deeper strategic decisions. Prism Flow is available as a one-time permanent purchase and includes its own progression and separate high score. The complete original mode remains fully playable without purchasing the expansion.
