Brain Teasers for Kids

Hidden Pictures

Find hidden pictures inside the illustrated scenes. The images you’re looking for are below each puzzle, and they’re well hidden!


Draw a complete loop past each number, traveling only vertically or horizontally between dots. Each number cannot have more lines next to them than its number. So, for example, a 3 should have exactly 3 lines around it – not 2, and not 4.

Logic Grid Puzzles

Use the provided clues to finish the puzzle. Put an O in the squares you know are correct, and an X in the squares you know are false. Use deduction logic to figure out the rest.

Use logic to turn these numbers into an image. Each number means an unbroken line of black squares, and they appear in the same order as the numbers. Each row goes from left to right, and each column goes from top to bottom. Every unbroken line of black squares is separated by at LEAST one empty box. Use this to your advantage!


Draw a complete loop by passing through each circle in the puzzle.Your loop cannot cross itself, or move diagonally. You must turn before and/or after passing through a white circle, but your loop cannot turn inside one. You must turn in each black circle, but your loop cannot turn in the square before/and or after passing through one.


Move only 1 line to make a true mathematical equation. Sometimes you might need to move a matchstick from an addition sign, or onto a subtraction sign!


Connect each number with its pair using lines that do not cross. All spaces must have a line passing through them. You may not use diagonal lines.

This is a decoding puzzle. Decipher the quoted phrase by finding the substitute letters. Each puzzle will have a hint! Sometimes it’s about the person who said it, and others are about the quote itself. Careful – sometimes the missing letter and its code letter could be the same.

Math Squares

Fill in the missing numbers to complete each number sentence. They’re all equations. The trick is to use both rows and columns to figure out the missing numbers.


Fill in the missing numbers to complete the puzzle. Every column, row, and grid must contain the numbers 1 through 9 without ANY repetition.
