كتاب ألغاز بديل لـ Spintronics Act Two

My kid tore through the first puzzle book in a week, so having a fresh copy of these challenges is a lifesaver. The pages are printed clearly, and the puzzles are just as engaging the second time around.

Ordered this after spilling coffee all over my original puzzle book, and it's an exact match page for page. The spiral binding lies flat on the table, which makes working through the later circuits way less annoying. Back to Act Two this weekend.

My cat chewed up the puzzle pages from my original set, so this replacement was a lifesaver. The print quality matches the first book exactly and the spiral binding lies flat while I'm working through the circuits. Back to Act Two without missing a beat.
