KernelLogic is a nonogram (picross) puzzle game wrapped in a cyberpunk shell. Every puzzle you solve decrypts a sector of a corrupted neural network, revealing the pixel art hidden inside a grid of clues. FEATURES - Classic nonogram/picross logic: use row and column clues to fill in the correct cells - Glitch cells that flicker and demand a fast, confident tap - Encrypted cells that need to be tapped twice to breach - Firewall cells that only unlock once their row or column is fully solved - Focus Isolation Mode: long-press a clue to isolate a single row or column when a puzzle gets dense - Dozens of hand-crafted levels across multiple zones, with new sectors added regularly - Clean, minimal cyberpunk UI with neon glow, glitch scanlines, and satisfying haptics and sound No ads interrupting your puzzles. Solve at your own pace: KernelLogic tracks your progress locally on your device. Unlock the full game once to access every zone and level, forever.

Verdict
The clearest difference is ads: KernelLogic at none against Polygrams's shown. Polygrams's advantage is iOS requirement (14.0 vs 26.5). On price, in-app purchases and device support there is nothing between them.
