NumCube
Read full descriptionHide full description
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?

Verdict
The clearest difference is in-app purchases: Merge Mania at none against NumCube's 6. Merge Mania also leads on update cadence (every 4 days vs weekly) and iOS requirement (13.0 vs 15.0). On price, ads and device support there is nothing between them.
