Every forestboard hides one stump for each row. Find them all by logic, before you run out of acornsmargaritas.
The rules
One stump in every row.
One stump in every column.
One stump in every color patch.
Stumps never touch, not even at the corners.
Controls
Tap a square to put an X on it, as a note that no stump is there. Tap again to clear it.
Drag across squares to mark them all. Start on an X to erase instead.
Double tap a square to reveal its stump.
-
A wrong guess leaves a red X and costs an acorna margarita 
.
You start with three, or one in silver acorn mode 
.
- Undo
Takes back your last tap or drag. Reveals, hints, and lost acornsmargaritas stay.
-
What if?
Opens a pencil layer to test an idea. Double tap for a pencil stump, which is never checked and costs nothing.
Keep turns your pencil X’s into real ones, and Discard throws them away.
Pencil stumps are small, and pencil X’s sit in the corner. A pencil stump that breaks a rule gets a red ring.
Hints
Each hint works once per puzzle, but not while What if? is on. A solve with a hint doesn’t earn the clean solve ★.
WoodpeckerParrot reveals a stump for you, in the patch with the fewest open squares.
Owl explains the next step you can work out, and makes that mark when you close it. It is also the only way to learn that one of your X’s covers a stump.
SquirrelGecko puts X’s on three random squares that have no stump.
