Ripple Effect 1.1

Ripple Effect is a highly-regarded logic puzzle game originating from Japan. In this engaging puzzle, players are challenged to fill a grid with positive integers while adhering to a set of specific rules.

Each section of the grid, referred to as a "room," must include consecutive integers ranging from 1 to the total number of cells within that room. Additionally, if identical numbers are placed within the same row or column, a separation requirement is enforced. Specifically, the separation must be at least equal to the value of the repeated number; for instance, if two cells contain the number '1', they cannot be adjacent and must have at least one intervening cell with a different number. This concept extends to higher numbers: two cells marked '3' in a row or column must be separated by at least three cells containing distinct numbers.
