Number Puzzle - online puzzle game

overview

Number Puzzle is a math logic game where you arrange number tiles to complete equations. Each puzzle gives you a set of equations with some numbers missing and a pool of tiles. Your goal is to place every tile into the correct blank so that all equations are mathematically valid.

rules

• Each equation has one or more blank slots that need a number tile.
• The tile pool contains exactly the numbers needed to fill all blanks.
• Every tile must be used exactly once.
• All equations must be mathematically correct when complete.
• Each puzzle has exactly one valid solution.

controls

• Click a tile in the pool to select it, then click a blank slot to place it.
• Click a filled blank slot to return its tile to the pool.
• Use Check to verify all equations at once.
• Use Hint to get one correct placement revealed.
• Use Undo to reverse your last action.
• Use New Game for a fresh puzzle.

scoring

Your performance is measured by solving time, number of moves, and hints used. Fewer moves and no hints yield a higher rating. Harder modes with more equations and complex operations earn bonus points.

tips

• Start with equations that have only one blank — there is only one possible answer.
• For division equations, the result must be a whole number. Use this to narrow choices.
• If stuck, try placing the largest or smallest tiles first — they often have fewer valid positions.
• Use Check frequently to spot incorrect placements early.
