Maths puzzles
Puzzles that practise real maths: adding and times tables, order of operations, factors, fractions and percentages, mental arithmetic and reasoning backwards — in games that make a fresh puzzle every time.
Where to start
New to these? Begin with Pot of Gold, Number Pyramid or Hundred Square Pieces — the gentlest rules here — then work along the list. Every puzzle has easy levels and a guide.
All 28 maths puzzles
Magic Sum
Place each number once so every row and column hits its target — by adding, subtracting, multiplying or dividing.
Magic Path
Find every number that fits the rule and join them all in one continuous path.
Dynamic Path
A maths question flashes up: find its answer on the grid and step onto it, building one connected path until every question is answered.
Pot of Gold
Start from a number at the bottom of the grid, apply the maths in each cell you step on, and climb to the golden pot with exactly the target number.
Sum Circles
Nine squares, four circles. Each circle is the total of the four numbers around it — plus colour totals and a 4×4 challenge.
Equation Square
A 3×3 grid of numbers with + − × ÷ between them. Make every row and column equal its answer — a crossword made of sums.
Number Chain
Double it, take 7, find a quarter… keep a running total in your head. Four levels from times tables to percentages and cubes.
Number Pyramid
Fill in the missing bricks by adding, subtracting — or multiplying in the times version. From first steps to algebra.
Make the Number
Six numbers, one target. Combine them with + − × ÷ to make it exactly — or play the kids’ version with four small numbers.
Letter Sums
Classic word sums like SEND + MORE = MONEY, and code sums that hide a ten-letter word. Column-by-column hints show how.
Number Order
Every row and column holds the same numbers and signs. Rearrange them until each line makes its total — BODMAS included.
Number Search
A maths word search: work out each clue, then find its answer hidden in a grid of digits — across, down, backwards or diagonally.
Number Memory
Study numbers in coloured shapes, then answer surprise questions from memory — counting, primes, digits, sums and positions.
Cross Numbers
Squares, primes, multiples, digit sums and links between answers — fill the grid so every maths clue fits.
BODMAS Game
Build equations that hit the target by applying the order of operations correctly.
Maths Crossword
A crossword where every clue is a maths question and the answers are numbers.
Times Grid
A multiplication square with the headers hidden. Divide to find them, then multiply to fill every square.
Number Triangles
Every side number is the sum of the two corners next to it. Find the hidden numbers.
Balance Scales
Shapes on balanced scales — work out what each one weighs. Algebra in pictures.
Hundred Square Pieces
Pieces of a number square with the numbers rubbed out. Use place value to fill every gap.
Factor Trail
Find the only trail to the flag, stepping only to factors and multiples, primes, or a times table.
Number March
Walk from Start to Finish where every step follows a hidden repeating pattern you have to discover.
Calcudoku
Fill an N×N grid with 1 to N — no repeats in a row or column — so every cage hits its target using its operation.
Killer Sudoku
Sudoku rules plus cages: the digits in each dotted cage add up to its total and never repeat.
Kakuro
A crossword with digits: each run of white cells adds up to its clue, using 1–9 without repeats.
Kakurasu
Each shaded square counts its column number in its row and its row number in its column. Make every total add up — addition practice disguised as logic.
Between Sums
Two shaded squares per line, 1 to N−2 in the rest; outside sums count what lies between.
Number Crossword
A crossword with no clues — place every listed number so the digits match wherever across and down numbers cross.
