Daily KenKen
The Daily KenKen offers one fresh arithmetic-logic puzzle each day, shared by every player. KenKen was invented by Japanese math teacher Tetsuya Miyamoto in 2004 to blend Sudoku-style placement with mental arithmetic. The once-a-day format turns it into a steady brain-training routine with a streak rather than a random stack of grids.
Daily KenKen Rules
Each day a single square grid loads — commonly 4×4 up to 9×9 — divided into outlined groups of cells called "cages," each labeled with a target number and an operation (+, −, ×, or ÷). The same puzzle is served to all players that date.
You fill the grid with digits from 1 up to the grid's size so that no digit repeats in any row or column, exactly like a Latin square. Additionally, the digits in each cage must combine using its stated operation to produce the target — for example a "12×" cage's cells must multiply to 12, and a single-cell cage simply holds its target number.
The puzzle is solved when every cell is filled with no repeats in any row or column and every cage's arithmetic checks out. Completing it extends your daily streak and logs your solve time.
Daily KenKen Strategy & Tips
Fill the single-cell cages first
A one-cell cage just equals its target, so write those digits in immediately. Each fixed number trims the candidates in its row and column right away.
List a cage's number combinations
For a cage like "6× over two cells," jot the digit pairs that reach the target. Then cross out any pair that would repeat a digit in the shared row or column.
Use subtraction and division both ways
Minus and divide cages don't fix the order — a "2÷" pair could be 1&2 or 2&4 or 3&6. Keep both arrangements open until row and column rules force one.
Solve daily to speed your mental math
Because the daily grid keeps a consistent size and difficulty, regular play sharpens quick arithmetic and combination-spotting. Track your time and the cages resolve faster each day.
Frequently Asked Questions
Is the daily KenKen the same for every player?
Yes. One puzzle is published per calendar date and served to everyone, so your solve time can be compared directly with other players who completed that day's grid.
How is KenKen different from Sudoku?
Both forbid repeating a digit in any row or column, but KenKen adds arithmetic cages — outlined groups whose digits must hit a target using +, −, ×, or ÷ — and it has no 3×3 boxes.
What do the numbers and symbols in a cage mean?
The number is the target the cage's cells must produce, and the symbol is the operation used to reach it. A cage marked "12×" needs its digits to multiply to 12.
Can KenKen be solved without guessing?
A proper KenKen, including the daily, has one solution reachable through logic — combining cage arithmetic with the no-repeat rule. Listing cage combinations and eliminating usually avoids any guessing.
