About game
Logic enthusiasts will immediately fall for the brain-teasing challenge found in Walls & Limits. You need to fill a grid where bold lines dictate the rules for each section. Every segment of length N requires you to place digits from 1 to N without any repeats. Because these segments overlap, horizontal and vertical constraints collide to make every move matter. Solving these logic puzzles requires careful planning since every cell belongs to two different groups at once. You can start with tiny 4x4 grids to get the hang of the mechanics before moving to dense 8x8 layouts. Keep an eye on those wall placements because they dictate your path to victory across 100 levels. Walls & Limits tests your mental sharpness without cluttering your schedule with complex rules. Play this free browser game today without any downloads or annoying registrations.
How to play
Bold lines split the grid into segments. A segment of length N contains numbers 1..N without repetition. Tap a cell, pick a number below. 'Note' mode (M button) — for pencil marks. 'Check' button highlights errors. Fill the entire grid correctly — you win!
