Overview
Tech is the difficulty showcase. Every level has obstacles, the board size changes constantly, and the piece count climbs higher than the earlier worlds. The puzzles are pure reading: route your beams around the blockers, find where coverage overlaps, and earn the solve.
The Mechanic: Peak difficulty
Tech adds no new rule. Instead it brings the blocked cells back on every single board, swings the sizes from 5x5 to 9x9 so you never settle into a pattern, and pushes piece counts to five. These are the hardest puzzles in the game. If you can clear Tech, you can read any board.

Level progression
Board sizes swing between 5x5 and 9x9 on purpose. Some levels are small and dense, others sprawl. Obstacles shape every solution.
