Spectrum Stack

Welcome to Spectrum Stack, a vibrant puzzle experience where color, logic, and rhythm collide in the heart of a living, breathing city.

High above the skyline, a metropolis of brilliant hues waits to be awakened. Each building, each block, each glowing hex tile holds a fragment of color - and only you can restore the city's full spectrum. Your mission? Paint every tile, fill every corner, and bring the urban canvas back to life.

Each level is a colorful challenge. The hex tiles aren't just spaces on a board - they carry energy, direction, and purpose. Tap a hex to unleash its color, watch it ripple across the grid, and think carefully about where each wave of hue will travel. Some tiles spread smoothly like fresh paint on glass; others demand precise, deliberate strategy. Plan ahead, trace the flow, and turn a fragmented grid into a seamless masterpiece.

As you progress through 12 unique levels, the puzzles grow bolder and more intricate - new shapes appear, the grids expand, and every board becomes a new architectural puzzle waiting to be solved. One misplaced tap can leave tiles cold and colorless; one perfect move can flood the board in brilliant blue.

Whether you're unwinding after a long day or sharpening your pattern recognition skills, Spectrum Stack offers the perfect balance of calm and challenge.

Can you fill every hex, master every grid, and build the ultimate color city? The spectrum is waiting - tap your first tile and let the colors flow.
