A Sudoku book cover has people scratching their heads.
The cover for “Sudoku Challenger: Big 360: includes a basic mistake.
Did you see it?
The hand has just written a 5 in one of the squares–but there’s already a 5 in the block.
The book actually exists.
According to multiple listings on eBay and book store websites, it typically costs $5-$10.
That’s not the only mistake, apparently.
“Also the random kanji they picked 彩 has nothing at all to do with sudoku(数独). It means hue or color,” noted one Reddit user.
