Solving Four Small Futoshiki Grids
Begin with the 4s and the 1s. A cell facing the open side of a sign is the larger one, so it cannot hold 1; a cell on the pointed side cannot hold 4. In a row with two or three signs, these two remarks usually leave a single place for the 4, and the rest of the row follows from the signs and from the digits already placed in each column.
Easy, Medium and Hard Sheets
On easy sheets, each grid starts with three extra digits and four extra signs, enough to fill the first row almost at once. Medium sheets keep only the clues the solution needs. Hard sheets remove every digit: the signs alone decide the grid, which turns a 4x4 into a real little puzzle.
For Classrooms and Families
Four grids per sheet give a child a short series to finish alone, and the numbered sheets let a teacher hand out the same puzzles to a group. Printed in black and white on A4, each sheet stays legible for young solvers; the 4x4 Futoshiki page offers one larger grid per sheet.
