ECHO vs Equalize

Every digit you place echoes across the board. ECHO GRID is a fresh kind of logic puzzle about reading the ripples. Place digits 1-3 on a 5x5 board. Each digit sends an echo up, down, left and right, traveling as far as its own value and adding that value to every cell it passes through. Match the target sum of every row and column to clear the stage! SIMPLE TO LEARN, DEEP TO MASTER - One rule: place digits. You'll get it in a minute - A single digit affects several rows and columns at once - plan ahead - Every puzzle has exactly one solution.

Listen to the echoes. One digit changes the whole board.

Every tile on the board holds a number. A single target appears at the top. Your goal is simple: make every tile match it. Use operation cards such as +1, −2, ×2, and ÷3. Each card affects an entire row or column—never just one tile. Swipe a card across the board and every number in that line changes at once. That simple rule creates the challenge. Fix one tile and you may throw another off. The order of your moves determines whether the board falls into place—or falls apart. SOLVED, NOT SHUFFLED Every board is verified by an exact solver before release. The move count shown is not an estimate; it is the true shortest solution. No impossible levels. No filler. EVERY MOVE MATTERS You receive exactly the operation cards required by the shortest solution, with no extras. Waste a move and the game tells you immediately. Undo is free and unlimited. Stars reflect mistakes made while solving. Using hints does not reduce your stars. A REAL DIFFICULTY CURVE Take on 486 levels across five chapters, from Basics to Master. Boards expand up to 6×6. Later, ×3 and ÷3 introduce competing divisibility rules, while locked tiles add another layer of strategy. The final chapter is called Master for a reason.
