Anagram Puzzles
A word puzzle where you rearrange all the letters of a jumbled word or phrase to form a different valid word or phrase, using every letter exactly once and no others.
Cryptic Crossword
A crossword variant, especially popular in the UK, where each clue is itself a compact wordplay puzzle — an anagram, a hidden word, a double meaning — rather than a plain definition of the answer.
Fillomino
A grid-division puzzle where you split the whole grid into regions (polyominoes) so that every cell's number equals the size of the region it belongs to — and no two same-sized regions touch edge-to-edge.
Slitherlink
A logic puzzle where you draw a single unbroken, non-crossing loop connecting dots on a grid, so the number of loop edges surrounding each numbered cell exactly matches that cell's printed number.
Hitori
A logic puzzle on a numbered grid: shade cells so no number repeats unshaded in any row or column, no two shaded cells touch, and the unshaded cells stay connected.
KenKen
A grid puzzle that combines Sudoku's no-repeat rows and columns with bold-outlined "cages" of cells that must combine, using addition, subtraction, multiplication, or division, to a printed target number.
Kakuro
A numeric grid puzzle, part crossword and part sudoku, where you fill cells with digits 1-9 so each run adds up to the sum shown in its shaded clue cell — and no digit repeats within a run.
Scanwords
A crossword variant where each clue sits printed right inside its own answer cells instead of a separate numbered list, so words interlock in a chain rather than the classic black-and-white grid.
Japanese Crosswords
A picture logic puzzle where number clues along each row and column tell you how many cells to fill in — solve them correctly and a hidden image emerges from the blank grid.
