Ages 9-10
Children learn a symbol cipher that is hundreds of years old. They make a decoder card with four grids, read the Academy motto and two other messages, then write a secret message in pigpen symbols for a grown-up to crack.
Ages 9-10
Children plan a sequence where choices have consequences. A ferry robot must carry a cat, a mouse and cheese across a river, never leaving unsafe pairs alone, and sometimes a passenger must be brought back. An expert torch-bridge puzzle then asks if four agents can cross in 17 minutes.
Ages 9-10
Children solve a classic puzzle in a child-friendly form. Four houses have different colours, pets and snacks, and eight clues give positions and links. Cut-out tiles let them slide ideas around before gluing, and the single question asks who owns the robot fish.
Ages 9-10
Children think sideways. Six riddles have obvious answers that are traps, and upside-down hint strips help when stuck. Two yes-or-no mystery cards let a family play detective by asking only closed questions. Children write a lateral riddle of their own.
Ages 9-10
Children shade a 15x15 grid using the clue numbers at the edge. A 5x5 warm-up teaches the method, then tips and checkpoints keep a long puzzle manageable. The shaded squares reveal a picture of what is inside the vault, and every square can be found by logic alone.
Ages 9-10
Children fix four wrong matchstick sums by moving one stick, then crack three letter sums in which each letter hides a different digit and the same letter is always the same digit. Tips such as 'a new first digit can only be 1' help them reason, not guess.

Children read short riddles closely, test each clue against a word bank (two words are extras), and underline the clue that gave the answer away. Number riddles use clues about size, even or odd and digit sums to find one number. Finally they write a riddle about an object at home.

Children make a real cipher wheel and learn how a substitution code works: every letter has a twin a fixed number of steps along. They decode three coded notes from the scene, each with its own key, and write a secret message of their own for a grown-up to crack.
Ages 7-8 · Grade 2Ages 7-8 · Year 3Ages 7-8 · Class 2Ages 7-8
Children use four different skills in one mission. Lock 1 is a number pattern, lock 2 a mini Sudoku, lock 3 a cipher word and lock 4 an odd one out. Each lock gives one digit, and the four digits open the museum door on a keypad.

Children become both the detective and the clue-maker. A grown-up fills in four clue cards (a riddle, a code, a map and an odd-one-out), hides them, and the child follows them in order to find the paper crown. Then they swap and the child writes the clues.

Children shade squares using the number clues at the edge of a grid. They climb three steps, a 5x5, a 7x7 and a 10x10, and the shaded squares reveal a picture that holds the last big clue in the case. Every puzzle can be solved by logic alone, with no guessing.

Children look at a problem in a new way. Wrong sums are drawn with sticks and moving one stick fixes each. A fence of three squares must be changed to two squares, and a six-stick teaser asks for four triangles. Children test ideas with real sticks.
