Button Patch - Logic Puzzle

Sew buttons onto a patchwork quilt.

Three rules, that's all:
• One button in every row
• One button in every column
• One button in every color patch
And no two buttons may touch, not even diagonally.

■ Solve by logic, never by guessing
Every puzzle has exactly one solution and can be solved with pure deduction. Notice "this color patch only has cells left in one row" and the next button practically places itself.

■ Hints that teach
A hint never just reveals the answer. It shows one cell you can be sure about and explains why in a single line. Get hints by watching an ad or spending coins.

■ 330 puzzles from 5×5 to 11×11
Start with easy 5×5 boards. Clear enough of one size and the next unlocks. 11×11 will make you think.

■ Controls that feel right
Tap a cell to cycle X → button → empty, or drag to mark many cells with X. Placing a button auto-marks the cells it blocks (you can turn this off). Unlimited undo, and unfinished puzzles are saved automatically.

■ A stitch to finish
Complete a board and a needle sews through your buttons one by one. Patches are told apart by color and pattern, so the game is comfortable if you have trouble telling colors apart.

■ Few ads
No banner ads. An interstitial appears only every few puzzles, when you move on to the next one. Hint and coin ads play only when you choose them. Remove Ads takes the interstitials away for good.
