Connect the Dots.
The game is of n*m grid, with random dots. Among the dots, two of them are of same colour. We have to connect those dots. We can build a path between two dots to connect.

While connecting, no two paths should cut each other.
No path can be drawn on the dot.

Simply say, the game is colourful, you have to find the matching color for all those colors. Connect dots of the same colour and move forward.
