Numbers

Numbers can be values, symbols or heights

Not every numbered grid is an arithmetic exercise. In these games, numbers can merge into a target, impose binary constraints or describe how a skyline appears.

Merge a value or complete a balanced binary grid

Number Merge slides tiles and combines equal values toward the selected target, including Sprint to 512. Binario is a Takuzu puzzle: every row and column needs equal numbers of zeros and ones, no three identical symbols in a row, and no duplicate completed rows or columns. Increasing the board size is not a calibrated difficulty rating.

A taller building hides a shorter one

Skyscrapers uses numbers as building heights. Rows and columns cannot repeat a height, while outside clues count the buildings visible from that direction. The same row can show a different count from its opposite side.
