Line Finder is a simple game I created during a hackathon in a couple of hours.

The theme of the game is “entropy.”

I implemented the game using JavaScript and basic DOM manipulation of HTML form elements to create the board.

Game Loop

The board cells are randomly assigned a value of either ╱ or ╲.

The player chooses a starting position on the bottom edge of the board and then presses “Go” to start the line-finding sequence.

The player’s starting point is like a laser and each cell acts as a mirror deflecting at a 90-degree angle based on its value.

The goal is to get the highest score by getting the longest chain of deflections without going off the board.

The line can revisit a previously visited cell. When doing so, the color of the line will change.

If you don’t like the board you’ve got, you can shuffle the board.
