Regionfill Area Puzzle

Survey the map, one plot at a time.

Regionfill Area Puzzle is a calm, offline number-logic game about counting. Every cell you fill must show exactly how many cells belong to its connected region — no more, no fewer. Fill a region correctly and its bold ink boundary locks into place, revealing the shape of the plot you just completed. Get it wrong and the plot glows red until you fix it.

THE RULE IS SIMPLE, THE LOGIC RUNS DEEP
• Every region's number equals its own cell count.
• Two different regions of the same size can never sit side by side.
• Some cells start as fixed clues; the rest are yours to work out.

TAP TO FILL, OR CONNECT FOR SPEED
Tap a blank cell, then tap a number to fill it. Prefer a faster hand? Switch on Connect mode, tap any numbered cell, then tap a blank neighbour to copy its number across instantly — perfect for finishing a region you've already figured out.

THREE PLOT SIZES
• Hamlet — a brisk 6×6 warm-up.

• Province — a 10×10 challenge for patient surveyors.
