Logic puzzle. Divide the whole grid into rectangles so that each rectangle contains exactly one number and its area equals that number. Drag across cells to draw rectangles. Solve as many as you can in 150 seconds.
The grid is scattered with numbers. Your job is to cut the whole grid into rectangles, one rectangle per number. Each rectangle must contain exactly one number, and the number tells you the rectangle's area — how many cells it covers. A number 6, for example, marks a rectangle of six cells, which could be 1×6, 6×1, 2×3, or 3×2.
Draw a rectangle by pressing on one cell and dragging to the opposite corner, then releasing. To redo a rectangle, just drag a new one over it — the old overlapping rectangles are cleared automatically. Tapping a single cell inside a rectangle erases that rectangle.
As you draw, a rectangle's border glows white when it is valid (exactly one number, correct area) and turns red when it is not, so you can fix mistakes at a glance. The puzzle is solved when every cell belongs to a rectangle and all of them are valid — then a fresh grid appears at once. Solve as many as you can before time runs out.
Start with the clues that have the fewest shapes. A 2 can only be a 1×2 domino, a 3 only a straight 1×3, and a prime number forces a single straight line — so these have just one or two possible orientations and often only one position that fits. Lock them in first; every rectangle you place walls off cells and shrinks the options for its neighbours.
Work from the edges and corners inward. A clue near a wall has fewer directions to grow, and a number in a corner is especially constrained. Use the board boundary the same way you use already-placed rectangles — as a fence that removes possibilities.
Watch for cells that only one clue can possibly reach. If a cell sits far from every number except one, that number's rectangle must stretch to cover it, which often pins the whole rectangle. Conversely, if two clues both want the same cell, placing one correctly frees the other — find the forced one first.
Every cell must end up inside exactly one rectangle, so use coverage as a check: a lone empty cell boxed in by finished rectangles tells you a nearby number has to reach it, and a clue that cannot possibly cover its required area in the space left means an earlier rectangle is wrong. In the timed mode, place the certain rectangles quickly and let them cascade.
