DrawPath is an app that lets you challenge your friends to a series of puzzles. You can draw the path you need to connect the given bricks.

With each puzzle, you will get points based on how well you can connect the bricks. Use your logic and creativity to get the highest score you can.

You can play DrawPath in two different ways.

Multi-Player – Play with friends or other players from around the world. 

Single-Player – If you don’t have any friends, you can play the single-player mode. You can choose the difficulty level and the number of bricks.
