Scoring & progression
Charge relays, then improve your timing
Each safe fork adds one charged relay. The saved record is relays charged; the Perfect count and streak are additional measures of your timing. The circuit accelerates as you charge more relays, and the displayed tier rises every three. A run ends when you take a breaker or let a junction pass without a choice.
Understand the challenge
What to watch in Signal Run
Follow the teal relay
Each junction presents a safe branch and a breaker. Read the current fork, then choose Left or Right. You can correct your choice until the fork. Once you have entered a branch, the next direction can be queued for the following turn.
Late switches build a perfect streak
Switching in the final 0.35 seconds earns perfect timing. That window rewards confidence, but waiting too long risks missing the junction entirely. Early safe choices still charge relays and count toward your personal best.
Build a better run
Signal Run strategies
- First practice choosing the safe branch early. Learn how the approach looks before aiming for the final timing window.
- After a turn, shift your attention to the next fork instead of continuing to press the direction you just used.
- If you spot an incorrect choice in time, correct it before the fork. Do not assume your first press has locked you into a branch.
Common questions
Before your next attempt
Do I need perfect timing to increase my record?
No. Every safely charged relay counts. Perfect timing builds a separate streak, so early choices are useful while learning.
Can I change my mind after pressing a direction?
Yes, until the fork. After entering the branch, a new choice can be queued for the next turn instead.
