Number LInk : Brain puzzle

■ Draw rectangles to match the numbers! Every number owns a rectangle with exactly that many cells. Press a number, drag to draw its rectangle, and cover the whole board to clear the stage! The rules take 10 seconds to learn, yet every board is a fresh logic challenge. Meet Shikaku — the classic Japanese rectangle-division puzzle. ■ How to play • Press a number and drag to draw a rectangle • One number per rectangle — the cell count must match the number exactly • Cover the entire board to clear! • Green means it fits, red means think again ■ 1,000 handcrafted stages From a cozy 3×3 warm-up to massive 20×20 boards. Higher stages bring bigger numbers and deeper deduction. ■ Fresh twists along the way • Ice cells — each completed rectangle breaks one layer (3 layers!) • Steel plates — complete 5 rectangles to unlock the hidden number • Bombs — cover the bomb cell before the countdown hits zero! ■ Daily challenge & ranking Take on a special challenge puzzle once a day and collect ranking points.
