What makes ECHO³ a different online brain puzzle?
ECHO³ is a free online logic puzzle game that runs in your browser, with no download, login or payment. One directional input controls three independent 4×4 boards, but each board interprets it differently. In NOW the piece moves normally, MIRROR reverses left and right, and ECHO moves according to your previous arrow. A blocked move still counts, so a good solution requires planning several turns ahead.
Can I continue a puzzle later?
Yes. ECHO³ automatically saves the current level, every submitted direction, ECHO's remembered arrow, and your undo history in this browser. Open the same puzzle again to resume on the same turn. It works without registration. If you clear browser data or switch devices, local progress does not transfer automatically.
