Linx is a spatial puzzle game. It is a retro logic game where the objective is to connect all the same colored bases with paths. The game has forty levels, but along with the two expansion packs Linx: Easy Set and Linx: Hard Set, there are 120 levels in total.
The goal of the game is to connect all the same colored bases with paths on a grid. Paths of different colors can not intersect and each tile on the grid can only contain one color or be blank with no colors. There are also areas on the grid where the paths can't cross. If you are having trouble distinguishing colors, the game features a colorblind mode. The instructions in the game are available in four languages, English, Polish, French and Dutch.
Pick a color (or a texture in colorblind mode) by clicking on a node, then click and drag to draw lines on the grid with that color. If you make a mistake, you can use the eraser to remove lines or you can reset the entire level. The idea is to connect all nodes of the same color without any differently colored lines crossing each other.
The concept of the game is similar to the 3D Logic series of 3D spatial logic games, but in 2D and with additional puzzle elements. There can be any number of bases of the same color and they all have to be connected in order to beat the level. There are also single bases which needs to be connected to themselves, taking up space on the grid.
