Tips and strategy

• Follow the beam cell by cell before you place anything. It starts moving to the right from the emitter, so you only have to decide where to turn it.
• Know your mirrors. For a beam moving right, a slash mirror turns it upward and a backslash mirror turns it downward.
• The target sits on the bottom row, so plan for the beam to travel down a column and arrive from above. Think about which single mirror could start that descent.
• Cells off the beam path can hold mirrors that do nothing, so keep your layout simple. Tap a mirror until the square clears to remove it.
• Use the live beam path as feedback. The highlighted squares show exactly where light goes, and Show a Solution gives a written hint when you need one.

What it exercises

Reflex Beam trains spatial reasoning and cause-and-effect thinking. You predict how a beam changes direction at each mirror, test an idea, and refine it using immediate visual feedback, which is a friendly way to practise geometry-style intuition. Each puzzle is quick to try, so it is easy to practise little and often.

Frequently asked questions

How do the mirrors work in Reflex Beam?

Tap a square once for a slash mirror, again for a backslash mirror, and a third time to remove it. A mirror reflects the beam by 90 degrees depending on its angle and the beam's direction.

Where do the beam and target start?

The emitter is on the left edge and fires to the right. The target is on the bottom row, and its column can change when you start a new puzzle.

How do I win Reflex Beam?

Place mirrors so the beam reaches the target square. The game detects it automatically and shows a success message. The emitter and target squares themselves cannot hold mirrors.
