📱 Please note: Because of their larger size, these puzzles may be more difficult to solve comfortably on mobile devices.
Take on the challenge, put your puzzle-solving skills to the test, and see how high you can climb on the leaderboard. Good luck, and happy puzzling! 🎯

Shade some cells to leave behind a single connected group — the cave — with no enclosed, shaded cells. In other words, all shaded cells must be connected by other shaded cells to an edge of the grid. All numbered cells must be a part of the cave, with each number indicating the total count of cells connected vertically and horizontally to the numbered cell including the cell itself.
Grid control: Click the mouse button at the selected cell to change the color of the cell. Second click will put auxiliary cross sign, which doesn't affect correctness of the solution, but helps visually. You can also drag the content of one cell to another with the mouse. More details about grid control are at the help page.
