The smallest room in the crooked house is locked with the smallest sudoku. Fill the grid so that every row, every column and every 2 × 3 box contains the numbers 1 to 6 exactly once.

Type a number in a square. Use the arrow keys to move around.

Four ghosts have drifted up to the séance table. Candid ghosts always tell the truth. Fibbers always lie. Tap each ghost to mark what you think it is, then check.

Place towers of height 1 to 4 so that every row and column holds each height exactly once. A number outside the grid says how many towers the giant can see from that side: taller towers hide shorter ones behind them.

Example: looking along a row that reads 2 1 4 3, the giant sees the 2 and the 4. The 1 hides behind the 2 and the 3 hides behind the 4, so he counts 2.

Every night at three, something knocks on the cellar stair. The knocks come in pairs: the first group gives the row of the square, the second gives the column. (The ghost knocks K as C, as ghosts always have.)
