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…
