Features: โข Tap an edge to draw a line, tap again to mark it crossed out, once more to clear โข Numbers fade to grey once they have exactly the right lines around them โข A clue turns red if you draw too many lines around it โข Undo any move with a single tap โข Three difficulty levels: 7x7 Easy, 10x10 Medium, 12x12 Hard โข Progress saves automatically, so you can stop and pick up later โข Stats and best times for every difficulty โข Plays fully offline A calm, addictive deduction puzzle that rewards patient thinking.

Verdict
The clearest difference is ads: Slitherlink at none against Flatbias's shown. Flatbias's advantage is update cadence (daily vs every 6 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.
