Futoshiki

Across the 5x5 grid in Futoshiki, every square waits for a digit from 1 to 5. Rows accept each number once, and columns follow the same rule. Inequality marks sit between neighboring squares and narrow the placement options. Early clues already point to spots for larger values and spots for smaller ones. Three difficulty modes set the puzzle layout before the grid fills in.

How to play?

Fill empty squares with the number panel below the board after selecting a cell. Work through the grid from top to bottom or move upward when another line gives a better clue. A wrong pattern at the end means an earlier placement broke the row, column, or sign rule. Go back through filled squares and replace the incorrect value. Change mode is available for edits. Double-tap a box to activate it, enter a new number from the lower icons, then tap the same box again to switch the mode off.
