**Important! The Power Pack requires at least the Act One kit to use it. It requires both Act One and Act Two to complete all of the puzzles.**
The Spintronics Power Pack gives you parts to charge your circuits with more power: an additional 6 V battery and two low-value resistors. It also includes a puzzle book with 11 additional puzzles.
This kit includes everything you'll need to play and complete the Power Pack puzzle book:
The parallelism between electronics and these mechanical circuits is extremely well thought out and implemented. It's a way of visualising and conceptualising electronics, with challenges that encourage you to want to move forward. All this with circuits that are fun to manipulate and solidly built. I don't know of any other scientific games besides Turing Tumble and Spintronics that promise so many years of fun and discovery. A quick word about the after-sales service, which is on par with the quality of the games. A part replaced, a game offered following a lost parcel. A dream for young and old alike!
