Ripple Rooms Solver: rules, how to use it, tips

Fill each room with 1 to its size so that any two equal numbers in the same row or column have at least that many squares between them.

The rules

The grid is divided into rooms outlined in bold.
A room of n squares contains each number from 1 to n once.
If the same number N appears twice in a row or column, there must be at least N squares between them.
Given numbers can’t be changed.

Using the solver

Choose the size, draw the rooms (or press Sample), then type the given numbers.
Press Solve and step through each number with its ripple shown.

Tips

Single rooms. A one-square room holds 1, so the squares directly beside it in its row and column can’t be 1.
Big ripples. A 5 rules out 5s for five squares in every direction — place large numbers first.
Only place. If a room’s 3 can only fit in one square, it goes there.
Every ripple. If a room’s number must go in one of two squares, a square that both ripples reach can’t be that number.
