📝 Our Take

AI-assisted editorial summary, grounded in our LEGO database and public community discussions. How we use AI

Spinjitzu Slam - Kai vs. Samurai is an action-packed battle set that delivers incredible spin-launching fun. This 2019 Ninjago subtheme successfully reimagined the classic spinner mechanic with ripcord-activated launchers, offering high-speed competitive play for fans of the ninja theme.

This set is perfect for younger Ninjago fans and tabletop gaming enthusiasts. The build is quick and accessible for kids aged 7 and up, while the included targets and dual spinners provide instant out-of-the-box play value and friendly competition.

Skip this if you are looking for a traditional building experience or large display model. At only 166 pieces, the focus is entirely on the play action rather than complex construction.

Investment Grade

⏳ Retired

As a retired 2019 Ninjago spinner set, 70684-1 occupies a niche corner of the secondary market. While battle packs and spinners traditionally appeal more to kids than adult display collectors, Ninjago remains one of LEGO's most enduring and resilient themes. The inclusion of exclusive Forbidden Spinjitzu (FS) variants provides a slight draw for completionist minifigure collectors. From an investment perspective, this set offers modest growth potential rather than explosive returns. The low initial MSRP of $19.99 means entry cost is minimal, but sealed copies are heavily reliant on niche Ninjago completionists. Sealed boxes hold steady value due to the popularity of the 'Secrets of the Forbidden Spinjitzu' season, but it is unlikely to outperform major display-oriented sets from the same era.

Great collection of trans-orange and trans-light blue elements, cheese slopes, and specialized spinner rotation plates, though heavily geared toward the action gimmick.
