Regin count

One rule. Endless “aha!” moments.

Fill It is a number logic puzzle that’s easy to learn and hard to put down. Fill the grid so that every group of connected matching numbers is exactly that size: a 3 joins two other 3s, a 5 makes a group of five. When every region is the right size, the puzzle is solved!

HOW TO PLAY
● Drag from a number to grow its region across empty cells.
● Drag across empty cells to count them out, and the right number snaps into place.
● Groups that are too big or too small glow red, so you always know where to look.
● Tap a group to clear it and try a different idea.

NUMBER TRAY PUZZLES
Some regions have no starting clue. Their numbers wait in the tray below the board, and you have to work out where each one belongs. Count out the right number of cells and the tile jumps into place.

BEAT THE CLOCK
Every level has a timer, but it only starts when you make your first move, so take a moment to study the board. Running low? Use Time Freeze to stop the clock, or continue with extra time.
