## What is Echo Gap?

Two Ns echo and vanish when they are exactly N cells apart.

Echo Gap is a calm-but-tricky number puzzle about distance. Drop tiles numbered 2 to 5 into the board. When two equal numbers sit exactly that many cells apart in a row or column, they echo and disappear. Tiles fall, new gaps open, and a single smart drop can set off a chain.

EASY TO LEARN, DEEP TO MASTER
• One rule you learn in ten seconds: a 3 needs exactly 3 cells.
• Echo lines show where your tile will land and which numbers it will reach.
• Chains multiply your score — and every chain sends an Echo Shock through the gap.

KEEP THE BOARD ALIVE
• Every few moves a pressure row pushes the board up, faster and faster.
• Stones arrive later — break them by catching them inside an echo.
• Fill Resonance to earn a Hammer, a Tremor or a Hush when you need a rescue.
• Second Wind saves you once per run.

PLAY YOUR WAY
• Classic 7×9 for quick runs.
• Wide 8×11 unlocks at 5,000 points for longer runs and bigger chains.
• Daily Challenge: the same sequence for everyone, every day.
• Combo multipliers, gold tiles and risky Edge bonuses for high scores.

MADE FOR EVERYONE
• Plays offline, no account needed.
• English and Vietnamese.
• Colour-blind friendly tiles, reduce-motion option, haptics and sound you can switch off.
• Plays great on iPad and large screens.
