SHIKAcookie: Shikaku Puzzle

SHIKAcookie is a rectangle-partition logic puzzle with a cookie shop to grow.

■ No guessing, ever
Cut the board into rectangles. Each rectangle holds exactly one number, and that number is its area. That is the whole rule.
All 486 puzzles are machine-verified to be solvable by logic alone — no lucky guesses, no "I just tried something and it worked".

■ Hints that explain WHY
Stuck? The hint tells you the next move and the reason behind it.
"This 4 must cover this square no matter how you place it." Read a few of those and you start seeing the techniques yourself.

■ Solve puzzles, grow your shop
Every solved puzzle earns coins, and coins build up your cookie shop — from a small stall to a full patisserie, 19 stages in all.
Even "just one puzzle today" moves you forward.

There is one small banner at the top of the screen.
Videos can be watched for coins or to refill your 3 hints, but both are entirely optional. Every puzzle is playable without watching anything, and clearing a puzzle refills your hints on its own. We never hold puzzles hostage behind an ad.
