Cross Math Leo: Number Puzzle
Math brain teaser & logic game
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Place the digits, complete the equations! Train your mind with addition, subtraction and multiplication puzzles. Find the missing number and get sharper every level.
Cross Math Leo is a crossword-style math puzzle made for people who enjoy thinking in numbers. The board arrives with digits and operators already in place — your job is to work out the missing number and complete the puzzle.
ADDITION, SUBTRACTION, MULTIPLICATION, DIVISION
All four operations show up together. Sometimes a simple sum is all it takes; other times a single row combines multiplication and subtraction, and you have to think it through. Place the right number and the grid falls into place.
HOW TO PLAY
• Look at the digits and operator signs already on the board
• Figure out which missing number makes the equation true
• Drop that number into the empty space
• Complete the puzzle and move on to the next one
SIMPLE RULES, SATISFYING THINKING
There's nothing to learn before you start. The numbers and the operations are right in front of you — all you have to do is find the one that's missing. But each puzzle pushes a little harder, and sometimes you'll need to juggle a few operations in your head just to pin down a single value.
SHORT BREAKS FOR YOUR BRAIN
Cross Math Leo is built for the small gaps in your day. Solve a few puzzles while you wait for the bus, during a coffee break, or right before bed. There's no clock racing against you — think as long as you like and try as many times as you need.
MATH PRACTICE THAT DOESN'T FEEL LIKE HOMEWORK
The easiest way to keep the four operations sharp is to turn them into a game. Cross Math Leo keeps your mental math habit alive without drills or lectures. The more comfortable you get with numbers, the faster you'll notice yourself solving each grid.
FOR EVERY AGE
• Students who want extra practice with the four operations
• Adults who like giving their brain a number workout
• Fans of logic puzzles and number grids
• Anyone who'd rather play with numbers than with words
THE FUN OF PLAYING WITH NUMBERS
There's a small but real satisfaction in staring at a grid, asking yourself "what number belongs here?", and then watching the whole board complete when you get it right. Cross Math Leo was designed to give you that feeling again and again.
Think about the numbers, solve the operations, find the missing piece. Download Cross Math Leo and turn math into a puzzle.
