Echo Frontier

One pulse of light. Multiple mirrors. All receivers must be lit.

Echo Frontier is a calm yet challenging logic puzzle. Emitters fire a single echo signal across the board; your job is to place and rotate mirrors so the pulse bounces past EVERY receiver before its energy runs out. It sounds simple—until the paths branch, the energy runs low, and you have less and less free space.

It's more than just matching patterns. You have to actually read the light's trajectory: each mirror '/' or '' bends the signal 90°, a relay recharges energy, and a wall absorbs the pulse. Plan the route, press EMIT, then watch the echo glide and light up the board.

■ HOW TO PLAY

Tap an empty cell to place a mirror.
Tap a mirror to rotate its direction ('/' ↔ ''), tap it again to remove it.
Lay out the path, press EMIT, and light up all the receivers.
