Logic puzzles
Pen-and-paper classics. Work out the answer by deduction, with a guide for every one.
New
Fill the grid so every row, column and box holds 1 to 9. Three difficulties, one solution each.
New
Open every safe square without setting off a mine. Three classic fields, and the first tap is always safe.
New
Fill the grid to match the number clues and reveal a picture. Every puzzle solves by logic alone.
New
Fill each thermometer from its bulb, with no gaps, so every row and column has its number of filled squares.
New
Fill each region with 1 up to its size. Equal numbers never touch, not even at a corner.
New
Shade exactly two squares in every region, so every shaded square pairs with exactly one other into a domino.
New
Divide the grid into rectangles by dragging: each holds one number, and the number is its area.
New
Shade a wall that leaves each number its island of that many squares. One wall, joined up, with no 2 × 2 blocks.
New
Place bulbs until every square is lit. No bulb may shine on another, and each number says how many bulbs touch it. Also called Akari.
New
Fill the grid with buildings so every row and column holds each height once. The clues say how many buildings you can see from each side.
New
Give every tree a tent of its own beside it. Tents never touch, and the numbers say how many tents each row and column holds.
New
Place stars so every row, column and region holds the same number, and no two stars touch, not even at a corner. Also called Two Not Touch.
New
Fill the tanks with water so every row and column holds its number of water squares. Water lies flat in each tank.
New
Fill the grid so every row and column holds each number once, and every greater-than sign between two squares holds.
New
Shade squares so no number repeats in a row or column. Shaded squares never touch, and the rest stay joined up.
New
Fill the grid with two colours: no three alike in a line, half of each, and no two lines the same. Also called Takuzu.
New
Shade squares so every row and column adds up to its target. Each square counts its column number to its row, and its row number to its column.
