01The core loop

Action → feedback → next choice
  1. 01Find source and receiver
  2. 02Place a redirector
  3. 03Check the path
  4. 04Route around blockers

↻Feedback changes the situation — the next round starts from there.

Walk through one round

A simplified design example. Situations and numbers illustrate the mechanic, not exact rules from a reference game.

  1. T1

    Turn 1 · The situation

    Red and blue beams must each hit a receiver, but you only have three relays.

  2. T2

    Turn 2 · The player chooses

    Place one relay to catch both beams and redirect each to its side.

  3. T3

    Turn 3 · The feedback

    Blue arrives; red is blocked by a pillar.

  4. T4

    Turn 4 · The next decision

    Use the other two relays to route red around the pillar.

How it plays

Beams travel straight and stop at walls or objects. Players use a limited number of redirectors or relays to bend the path, and a lit receiver triggers a switch. Multiple colors or crossings add constraints.

What the player weighs

  • Use a relay here or save it for another beam
  • Take the short line or a longer clear route

03One mechanic, different implementations

The Talos Principle
T

The Talos Principle

P1

Players carry connectors to relay colored beams to receivers; beams can't cross through each other, and jammers and boxes complicate routing.

Portal 2
P

Portal 2

P2

Thermal discouragement beams are steered with redirection cubes, relays and portals to hit catchers, and they hurt players and turrets along the way.

The difference worth noticing

The Talos Principle emphasizes multi-beam topology; Portal 2 blends beams with portals and danger.

04What could you combine?

Fusion · Original design proposal · not an existing feature
Guiding the BeamPuzzles & deduction+

Swap beams for canals and relays for diverters, and the same routing rules make irrigation coverage puzzles.
