Pixel: The Challenge
Collect every Pixel. Master ice, fire and traps. Reach the Plenum.
A 3D puzzle game in the spirit of the great tile-based logic classics — 80 hand-crafted levels, every single one provably solvable.
One grid. One plan. One way out. In Pixel: The Challenge you collect every Pixel on each level, find the right keys and cross water, ice, conveyor belts and monsters until the Plenum portal opens. The logic is grid-clear like the classics — the world is real 3D. And because a solver proves every solution in advance, no level is down to luck.
What makes it tick
80 levels, guaranteed solvable
Eight worlds, 80 hand-built puzzles. A solver proves every solution in advance — you'll never face an unfair or impossible level.
Classic logic, real 3D
Deterministic grid logic like the 16-bit classics, paired with fluid 3D animation. Think, plan, execute cleanly.
