Futoshiki is a Japanese number puzzle that blends clean logic with a clever twist. Fill a 5×5 grid so each row and column contains the numbers 1 to 5 without repeats, then satisfy the inequality signs between cells.

Every puzzle has a single solution. Use deduction from row and column constraints plus the < and > signs to narrow candidates.
Choose easy for a relaxed warm up, medium for steady challenge, or hard when you want deep thinking. A built in generator provides fresh boards each time.
Clear symbols and crisp layout keep attention on reasoning, perfect for short breaks or long, satisfying solves.
Place numbers 1 to 5 so there are no repeats in any row or column.
Respect inequality signs. For example, 3 > 1 means the upper or left cell must be larger than the adjacent cell.
Scan for strict inequalities to lock obvious highs and lows.
Use row and column elimination to form candidate lists.
Cross check neighbors against < and > to prune candidates.
Pencil in possibilities, then promote certain values when only one candidate remains.
🔍 Start with rows or columns that already contain many clues
📐 Treat < and > like arrows that order cells from small to large
🧮 Track used numbers per line to find singles quickly
⛳ When stuck, compare two neighboring cells to force a choice
