## What is Ripple Effect?

Ripple Effect is a logic puzzle with simple rules. The puzzle consists of a rectangular board divided into "rooms". Each room must be filled with each of the numbers from 1 to the number of cells in the room. If two identical numbers appear in the same row or column, at least that many cells with other numbers must separate them. For example, if two 4s appear in the same row, then they must be separated by at least 4 cells.

### 1/5 — Doesn’t work

*2025-07-17*

No matter what i do, delete reload etc. none of the squares will highlight or populate for me. 😡

### 4/5 — マスが上に１マスずれる

*2021-04-27, version 1.1.4*

Androidを使っていた時は無かった波及効果がiPhoneにはあったので喜んで即インストールしました。が、入力したいマス目をタッチすると1マス下のマスに入力するようになってしまいます。全くできないわけでは無いのですがやりづらいです。直していただけたら有料問題も購入するのですが‥

### 5/5 — Excellent Game

*2013-11-02, version 1.0.4*

I have been looking for this particular Sudoku type game since I found it in a paper a short while ago. Fantastic game, played for just a sort while and then bought the upgrade for 69p, excellent value. Keep up the good work and thanks for a great game.
