Odd One Out Reasoning
Volume 2
The interactive edition for ages 6–9 (Year 2 to Year 4): 30 pages of five rows, six levels — shape families, turned or flipped, hidden numbers, shading and position, shapes inside shapes and symmetry. Tap the odd one out; a wrong tap tells you that picture still matches, a right one tells you why it is different. Same puzzles as the printed book.
