About the game
Ripple Effect is a number logic puzzle where every number makes waves. The board is split into rooms, and a room with n cells must hold the numbers 1 to n, each exactly once. The catch is distance: if the same number x appears twice in one row or column, the two copies must be more than x cells apart. So two 1s can never sit side by side, two 3s need at least three cells between them, and big numbers push each other far away.
The twist is that you can see those waves. Select any filled cell and its number sends a ripple along its row and column, painting every cell inside its reach. That painted zone is exactly where the same number is not allowed, and if a twin is already sitting inside it, the clash splashes red. Small rooms and big numbers are the best starting points, and the later boards hide a step where you test a number, watch it ripple into trouble, and rule it out. Thirty puzzles grow from 5x5 to 8x8, every one with a single answer.
