About this challenge
Reef Echoes is challenge 3 in the ten-part Echo Steps collection. It uses the same core rules as the other challenges in this family, with its own settings: goal: 6; flash duration: 560 ms. Choose it when you want a easy round, or use the previous and next buttons to adjust the challenge.
Rules and controls
Watch the four illustrated pads in Reef Echoes, then repeat their flashing sequence in order. Tap the four numbered pads after the demonstration finishes. Your result appears above the board when the round ends. Restart begins a new round; it does not continue the previous board. The game keeps a small record of completed rounds in this browser.
Make your next round better
Group the sequence into small chunks rather than remembering isolated taps. Wait until the prompt says your turn. The sequence grows by one step after each successful round. If the current challenge feels too demanding, go back one level and focus on the basic pattern before increasing the pace or board size.
Playing on a phone
The board adapts to the width of your screen. Use the displayed buttons or direct touch controls. For word and number inputs, tap the text field to bring up the keyboard. Put your phone in portrait orientation for the clearest view of the controls. Timing games may feel different across devices because screens and input hardware respond at different speeds.
Part of a collection, with a clear goal
