TANGRID PUZZLE

Tangrid is not the only puzzle of its kind in our rating of games. There are also plots with unraveling lines. See, each level is a kind of puzzle, a tangle of lines (straight lines) with nodes, pulling on which, they must be unraveled. Unraveling should be understood as actions aimed at moving nodes, as a result of which, no segment will intersect another.

Intersecting segments are marked in red, and untangled segments (if they don't intersect) are marked in green. The white nodes are immobile, while the red and green nodes can be moved. Drag them so that all the lines turn green. Note that the keyword here is EVERYTHING! Only when all the lines on the field are green will you be able to move on to the next stage. The game has only 20 levels, and the first 15 are solved quite simply, but the remaining five will have to work on.
