Quaddro 2 is an Android puzzle game developed by Mental Lab Games. It is a full version game that offers 80 levels with progressive difficulty levels. The game is designed to improve concentration and logic skills.

The gameplay is simple yet challenging. You move the dots freely until you form a square with 4 or 9 dots. You can move as many dots as you want at the same time, similar to dragging a snake across the level. The dots can be varied in up to 3 colors: red, green, and blue, but squares will only be formed by dots with the same color.

The game packs many types of modifiers that will make you think outside the box. There are movable platforms that change the layout of the level by moving pieces of the board vertically or horizontally. Turn Modifier allows you to rotate boards and its contents in 90 or 180 degrees. Mirror Modifier swaps platform places, while Wall Modifier blocks the access to certain parts of the level until you make a specific action. The Timer Modifier adds an extra level of difficulty to the game as the level layout changes every time the timer runs out.

Overall, Quaddro 2 is an excellent puzzle game that offers a lot of challenges and fun. It is perfect for people who enjoy using their brainpower to solve puzzles.
