GAME INSTRUCTIONS
What is the goal of the game?
In Prism Puzzle, students must guide a laser beam from the emitter to every crystal on the board. By rotating mirrors and using prisms, players redirect the light until all crystals are lit. With 50 levels of increasing difficulty, it's a hands-on way to explore how light behaves while practicing logical problem-solving.
Recommended age and educational level
Recommended for students ages 8 and up, from 3rd grade through middle school. Early levels introduce the mechanics gradually, while later puzzles challenge older students with multi-step solutions. It works well as a classroom warm-up, a science center activity, or a reward for early finishers.
How to play: single-player or multiplayer
This is a single-player game. Here's how it works:
- The laser fires from the emitter, and the goal is to light up every crystal.
- Tap a brass-ringed mirror to flip it between / and . The beam changes direction instantly.
- A prism (with a glowing center) lets the beam pass through and splits off a copy at a right angle.
- Walls block the light, and bolted steel mirrors cannot be rotated.
- A counter shows how many crystals are lit out of the total.
- Each level has a par, just like in golf: the optimal number of moves. Finish at or under par to earn 3 stars.
What do you learn from this game? Learning and skills
- Physical science (light and optics): students see that light travels in straight lines and that mirrors reflect it, changing its path.
- Geometry and angles: diagonal mirrors turn the beam 90°, reinforcing ideas about angles, lines, and direction.
- Spatial reasoning: players mentally trace the beam's path across a grid.
- Logical thinking and planning: solving each level in the fewest moves requires thinking several steps ahead.
- Computational thinking: breaking a problem into steps, testing, and debugging a solution.
- Persistence: trial and error builds a growth mindset as students retry levels to improve their score.
Tips to get the most out of this game
- Trace before you tap: encourage students to predict the beam's path before making a move.
- Start with the fixed steel mirrors: they limit the options and often reveal the solution.
- Use the par challenge as a goal: can the class find the optimal solution?
- Pair it with a lab: use flashlights and small mirrors to recreate a level in real life and discuss the law of reflection.
- Have students explain their strategy aloud or in writing to strengthen reasoning and vocabulary (emitter, reflect, angle, path).
