Molehill: Brain-Logic Puzzle

Molehill is a brain-logic puzzle set in Momo the mole's garden.

Every board hides moles: one in each colour region, one in each row, one in each column, and no two moles ever touch — not side by side, not corner to corner. Every board has exactly one answer, and the game proves it before you ever see it.

How you dig
• One tap puts a ✕ on a cell. ✕ means: no mole here. Tap again to clear it.
• Two fast taps dig up the mole.
• Not sure yet? Press and hold to plant a maybe flag. Flags are free and never cost a heart.
• Slide to mark a whole line of empty cells in one move.
• Three hearts, and thirty seconds of clock for every row on the board.

Learn the techniques
• Boards start at 5×5 and grow to 11×11, and get cleverer as they grow.
• Five named deduction techniques — Lone Burrow, Full Row/Column, Tunnel Squeeze, Fence Count, Shadow Test — each with its own lesson.
• The hint shows you where to look and why. It outlines the row, column or colour that forces the answer, instead of opening the square for you.
• Four tools on the dock: Auto ✕, 2× Time, Mole and Hint.

Two more puzzles in the garden
• Plumber opens at level 27. Turn the pipes until the peanuts reach every burrow.
• Shikaku opens at level 34. Cut the field into boxes, one number in each, and every box exactly as big as its number says.
• After that, one of the two turns up every seventh level.
