Browser memory and rule-shift puzzle

Read the relay, apply the rule, beat the static.

SignalStack turns short sequence memory into a sharper browser game. Every challenge shows you a live packet, then forces one rule change before you replay it. Some rounds mirror the lanes. Some shift every pulse forward. Some echo the tail. The win comes from staying calm long enough to rebuild the right signal under pressure.

Play SignalStack How to play
  • Four readable channels, four handcrafted towers, and one deterministic daily relay
  • Distinct modifier rules that make memory matter more than frantic tapping
  • Built for one-more-run score chasing, daily comparison, and future challenge sharing

Why it lands

  • The core loop is instantly understandable, but the modifier changes stop it from feeling like a flat Simon clone.
  • Rounds stay short enough for replay, while the rules add just enough mental friction to create tension.
  • Daily seeds and future community challenge codes give the concept room to grow without bloating the MVP.

Keyboard shortcuts: 1, 2, 3, 4 to enter pulses. Backspace clears the current entry.

Choose a tower

Pick a relay rule, then stack the right reply packet before the static closes in.

The daily uplink uses the current UTC date, so every player gets the same packet list on the same day.

Ready Watch first, then transmit.

Choose a tower to begin

SignalStack rewards clean reconstruction. The sequence flashes once, the rule changes how you must answer, and a shaky guess can break the whole run.

Scoring notes

Memory with a real twist

You are not only remembering the packet. You are transforming it correctly under a live rule.

Readable in one glance

The four channels stay consistent and high-contrast so mistakes feel like judgment misses, not UI confusion.

Ready for daily competition

Deterministic seeding makes today’s tower identical for everyone and easy to grow into shared leaderboards later.
