Fillomino Puzzle

emoji_eventsGoal

Fill the grid with numbers so that every number 'n' belongs to a group of exactly 'n' identical numbers.

gavelRules

• Every number sits in a region of exactly that many cells
• Two regions of the same number may never touch side by side
• A finished region gets a solid outline; a wrong one turns red
• Fill every cell to finish the puzzle

sports_esportsHow to Play

• Pick a number, then tap a cell to write it
• Drag out of a number — a given or one of your own — to grow that region with it
• Drag across empty cells to paint a whole region in one stroke
• Tap a cell holding the same number to rub it out, or use erase mode
• Undo steps back a move — a whole drag counts as one
• Keyboard: arrows move the cursor, 1-9 write, Backspace erases, Z undoes

lightbulbTips

• Start from the givens — a 1 is a region all by itself
• A region that is already the right size is settled; the outline tells you
• Watch for cells that get walled in: a region that can no longer grow to its number turns red
• Two same-numbered regions touching is the same mistake as one region being too big
