How to play Echo Sounding
A daily deduction puzzle: three new grids every day, the same for everyone.
- A hidden layout of reflectors sits somewhere in the grid.
- Ping any cell and the only thing you learn is the distance, in steps, from that cell to the nearest one.
- Narrow the reflectors down from a handful of pings, mark where they must be, and check your answer.
- Each ping costs a point, so find them in as few as the par, then share your result without spoiling the grid.
