Happy Filled Glass

Start by studying the level to identify the water supply and the container. Use your drawing tool to create a path from the water supply to the target glass. Make sure the line is solid to permit the water to move without interruption. Prevent obstacles that may stop the water's path. Finalize the line to trigger the water transfer. Observe as the water follows your drawn path to enter the glass. Adjust your approach in following levels as obstacles increase.
