Goal: Shade cells so all 5 rules are satisfied.
1οΈβ£ Shade cells to form "stones" in each region.
2οΈβ£ Numbers in regions = exact cells to shade. No number = shade at least 1.
3οΈβ£ Connected: Shaded cells in each region must be orthogonally connected.
4οΈβ£ No cross-border: Shaded cells can't touch across region borders.
5οΈβ£ Gravity: When stones "fall down", they must fill the bottom half completely.
π‘ Tip: The gravity rule means each column must have exactly half its cells shaded. Use this to deduce!
π±οΈ Controls: Click/tap a cell to shade or unshade it.
