Classic 15 Slide Puzzle
Slide tiles into order — a classic test of planning
Arrange the numbered blocks from 1 to 15 by sliding tiles into the empty space. Only a tile next to the blank can move. Great for spatial thinking and looking a few moves ahead.
Sudoku
The world-famous logic grid — rows, columns, boxes
Fill the 9×9 grid so every row, every column, and every 3×3 box contains the digits 1–9 exactly once. No guessing required when you use pure logic. Three difficulty levels with fewer starting clues as you go harder.
Make 24
Mental arithmetic challenge — hit exactly 24
You get four numbers. Use each one exactly once with +, −, ×, ÷ and parentheses to make the total 24. Order of operations matters. Ideal for practising flexible calculation — the same skill used in Vedic mental maths.
Magic Square
Every line adds to the same magic number
Place numbers so every row, every column, and both main diagonals add up to the same constant. Easy and Medium use a 3×3 grid (sum 15); Hard uses a 4×4 grid (sum 34). A beautiful mix of addition and logic.
KenKen (Calcudoku)
Latin square meets arithmetic cages
Fill the grid so each row and column contains digits 1 to N once. Outlined cages must also equal the target using +, −, ×, or ÷ (for example 3+ or 8×). Combines Sudoku-style logic with real calculation.
Kakuro
A number crossword built on addition
Fill white cells with digits 1–9. Each run of cells must add up to the clue and must not repeat a digit. Gold clues are across; blue clues are down. Like a crossword where every answer is a sum.
