Rows and columns of numbers may look random, but hidden rules are waiting to be found. Can you identify the number piece that satisfies both patterns?

This reasoning puzzle is easy to learn and satisfying to solve. Study the arrangement and use the numbers and their positions as clues.

How to play:
• Work out the pattern across the row
• Work out the pattern down the column
• Choose the piece that matches both conditions and move it to the crossing square

Knowledge is not the key—observation and insight are. Begin with two-digit numbers, then take on three-digit challenges as the stages progress.

There are 40 stages to complete. Think through each puzzle at your own pace and ask yourself: what rule is hiding in this sequence?
