No.255The Talos Principle01The core loop
Action → feedback → next choice- 01Find source and receiver
- 02Place a redirector
- 03Check the path
- 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.
- T1
Turn 1 · The situation
Red and blue beams must each hit a receiver, but you only have three relays.
- T2
Turn 2 · The player chooses
Place one relay to catch both beams and redirect each to its side.
- T3
Turn 3 · The feedback
Blue arrives; red is blocked by a pillar.
- 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
02Start small
Scope is an editorial estimate for the minimum prototype, not the reference game or a production schedule.
03One mechanic, different implementations

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

Portal 2
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.
Case notes are Yoroll editorial summaries; rules may change between versions.
04What could you combine?
Swap beams for canals and relays for diverters, and the same routing rules make irrigation coverage puzzles.

Drone Logistics Network
No belts needed: flying units deliver where needed, but you have to keep them supplied.

Conveyor Routing
Moving items from A to B is easy; keeping every line from tangling is the game.

- 01Plan source and destination
- 02Lay belts around obstacles
- 03Watch flow and jams

Flow Splitting and Ratios
Feeding several machines from one input comes down to exact ratios and even splits.
