About this book

Umi leads the Sharp Eyes Club, a team of six friends who love to change things when nobody is looking. Each puzzle shows two nearly identical pictures. Children look, compare, circle the differences in picture 2, then tick off the magnifiers when every clue is found.

The book climbs through four levels, 25 puzzles each: from one big, clear change per picture at Level 1 to four or five subtle but fair changes at Level 4. From Puzzle 36 onwards, a hint from Umi is printed upside down at the bottom of the page — just turn the book around when you are stuck.

There are no timers. Careful beats fast, and every puzzle was built from one master picture and changed on purpose, then checked against its answer key.

  • Compare two pictures and find every difference
