Trò chơi câu đố với các quy tắc rất đơn giản có tác dụng phụ

Side effects is a puzzle game based on three very simple rules.

1. All grid cells must have the same value to win. All 0 or 1.

2. When a cell is selected, its own value is swapped as well as the North, South, East and West cells (but not diagonals).

3. Cells swap from 0 to 1 or from 1 to 0.

The first levels of each set are there to learn the principles.

You can challenge your friends through Google Play Services, publish your scores and compare.

There are two competition modes

- Free move: only the number to moves is counted, take your time before performing a move.

If you make the level in time and with a minimum number of shots, you maximize your score.
