Drag mechanics
Press and drag from a starting point. The line extends one cell at a time. Both games respect the grid: no diagonals, no jumping, no crossing your own path.
A single line drawing puzzle. One continuous stroke instead of multiple connecting pipes — same satisfying line logic, different shape of puzzle.
What changes
Flow Free has you connect every coloured pair without crossing — multiple short pipes that fill the grid. monostroke has you trace one continuous line from a single endpoint, with the goal of making that line as long as possible without crossing itself.
It is the same family of line-drawing logic, but the structure is different in a way that changes how you think. Flow Free is "all the pipes must reach their target." monostroke is "one stroke, find the longest valid path." Both are clean, both reward spatial reasoning, both are at home on a phone.

What stays the same
Both games reward the same kind of spatial planning: thinking ahead about which cells will be reachable later, planning around obstacles, undoing and re-routing when a path dead-ends. If you enjoy that kind of puzzling in Flow Free, you'll feel at home in monostroke.
Press and drag from a starting point. The line extends one cell at a time. Both games respect the grid: no diagonals, no jumping, no crossing your own path.
No timers, no streak nag, no daily-login pressure. Open the app, play a few levels, close the app. Your progress is local.
Designed for portrait, single-thumb play. Both games work well on phones; both also scale to tablet without losing readability.
