Laser Maze Jr. is a multi-challenge logic game where one must place a selected assortment of mirrors to ensure a number of targets are hit with a laser-beam. Unlike its more challenging counterpart, this version is aimed at younger audiences with simpler challenges. The grid comes more heavily themed and is surrounded in a protective wall that contains an immobile laser module. The laser can also not be calibrated as it can in the standard version, meaning that the laser often misaligns after a few bounces. Pieces include standard mirrors, a splitter, and blocking pieces.

For each challenge, place the noted additional pieces such that the laser hits all the designated targets simultaneously.
