## What is NumCube?

NumCube is a 3D rectangle puzzle where numbers come to life.

Each number tells you how many cells its rectangle must cover. Drag to draw rectangles on the grid — every rectangle must contain exactly one number, and its area must match that number perfectly.

No timers. No penalties. Just pure logic.

FEATURES
• Tons of hand-crafted levels with progressive difficulty
• 3D top-down view — blocks rise from the grid, taller blocks mean bigger numbers
• Drag to draw, release to place — intuitive one-finger controls
• Hint and Skip tools to keep you moving forward
• No time limits, no failure — solve at your own pace
• Clean minimal design with smooth 3D visuals

NumCube reimagines the classic Shikaku puzzle in three dimensions. Numbers become towers, rectangles become regions, and the grid becomes a landscape of logic.

Can you divide the grid perfectly?
