Happy Glass Draw lines

Happy Glass Draw Lines is a puzzle video game developed by a mobile game studio, released for iOS and Android platforms. The game presents a series of levels, each containing a stationary glass positioned on a flat surface. A water source, typically a pipe or faucet, is located above the glass. The objective is to fill the glass to a marked fill line by drawing a single continuous line that guides the flowing water into the container. The drawn line acts as a physical barrier or channel, redirecting the water’s trajectory. Obstacles such as platforms, spikes, or moving blocks are often placed between the water source and the glass, requiring the player to navigate the water around these impediments. The game employs a physics engine that simulates water flow, gravity, and collision. Each level has a limited amount of water, and the line must be drawn using a finite length of virtual ink. Success is achieved when the water level inside the glass reaches or exceeds the designated fill line. Failure occurs if the water runs out, spills over the glass, or if the drawn line is too short to complete the path. The game includes a star rating system based on the efficiency of the solution, with fewer drawn lines or shorter line lengths earning higher ratings.

Gameplay and controls are executed through a touchscreen interface. The player initiates a level by tapping the screen. To draw a line, the player places a finger on the screen at a starting point and drags it across the surface to create a continuous path. The line is rendered in real time as the finger moves. Once the finger is lifted, the drawn line becomes a static object in the game world. The water then begins to flow from the source, following the path defined by the line. The player cannot modify or erase a line after it is drawn; the level must be restarted to attempt a different configuration. A restart button is located on the screen, typically in the upper corner. The game provides a limited number of line segments per level, indicated by a counter. The player can also view a replay of the water flow after a successful or failed attempt. The interface includes a level selection menu, a settings option for sound and vibration, and a hint system that may be unlocked through in-game currency or advertisements. The controls are designed for single-finger input, with no multi-touch or gesture-based commands required.
