Cutle

What Is Cutle?

Cutle is a quick shape-cutting puzzle game. Your goal is simple: draw one clean cut through the shape and split its filled area as close to 50:50 as possible.

How to Play Cutle?

Press or click inside the game board, drag a line completely across the shape, and release to make your cut. Some Archive shapes contain holes or multiple separate regions. Cutle measures the total filled area across all regions. After a valid cut, Cutle separates the two sides and displays the rounded area ratio and precise score. The goal is to achieve a 50:50 split, but even a 48:52 split is a good result.

How does Cutle measure area?

Cutle estimates the filled area on a 600 × 600 canvas. It checks a regular grid of points spaced 3 canvas units apart. Points outside the shape are ignored. Every point inside the shape is assigned to one side of your cut line, and the number of points on each side becomes that side’s estimated area. This sampling method works with irregular SVG paths, holes, and shapes made from separate filled regions.

How is the score calculated?

Cutle divides each estimated area by the total sampled area to get the two percentages. The large ratio is rounded to whole numbers, which is why a close cut can appear as 50:50. The detailed ratio on the smaller line keeps one decimal place. Cutle takes the smaller of those two percentages and multiplies it by 2: score = smaller side × 2 For example, a precise ratio of 49.6:50.4 gives a score of 99.2%.

How do you get 100%?

You get 100.0% when the precise ratio rounds to 50.0:50.0. Before that rounding, the smaller side must contain at least 49.95% of the sampled area. The difference between the two sides must therefore be no more than 0.1 percentage points. Start with a line of symmetry when the shape has one.
