Logic Edition

Every row, column, and box holds each number exactly once.

Shade cells until every row and column reads clean.

Each symbol once per row, once per column.

Fill the grid with zeros and ones. Balance required.

Locate the fleet using row and column counts.

Connect every island. Build the network.

Sudoku logic, but the boxes become chains.

Each number once per row and column. Arrows point to the smaller.

Divide the balls into groups of six around a single white ball.

Jump diagonally, capture as you go, and keep the chain alive.

Each row belongs to one number, appearing exactly that many times.

Every strip of white squares holds 1 up to its length, once each.

Split the grid so every domino in the set is used exactly once.

Number the hexagons 1 to 18 into one unbroken trail.

Add tokens so no two ever touch, not even at a corner.

One star per region, row, and column. No two may touch.

Number every stone 1, 2, or 3. Touching stones never match.

One black and one white pawn in every row and column.

Each region holds 1 up to its size. The same number never touches.

Add pawns to hit the target count of three-in-a-row lines.

Two paths through one maze. They must never cross.

White squares take 0 or 1, shaded take 0 or 2. Hit every total.
