TrezeLines

TrezeLines is a masterclass in physics-based puzzle design, challenging you to draw exactly thirteen lines per level to manipulate gravity and guide colorful balls safely to the exit. This creative problem-solving game demands both precision and imagination as you craft slopes, ramps, and barriers that interact with the environment in real-time. The rule 'thirteen lines only' forces you to think economically—each line must serve a purpose, and wasted lines mean failure.

The gameplay loop is addictive: you start a level, observe the ball's path, pause to sketch your solution, then press play to watch the physics simulation unfold. The pleasure comes from seeing your cleverly designed lines work in perfect harmony—a ball curving around a spike, bouncing off a well-placed wall, and rolling into the goal. As you advance, levels introduce moving obstacles, anti-gravity zones, and teleporters that require multi-step planning. The timing challenge also intensifies because you can draw lines while the action is paused, which adds a strategic layer of foresight.

This is a perfect game for fans of brain-teasers, physics sandbox games, and platformer puzzles. The minimalist vector art style keeps focus on the mechanics, and the progressive difficulty curve ensures you're always learning. A pro tip: always leave one or two spare lines for fine-tuning—the most elegant solutions often require last-second adjustments. For speedrunners, line efficiency is your main score metric; try to solve levels with the fewest lines possible within the thirteen limit. The game also includes a level editor, letting you share your creations with the community.
