New Partnership Announcement!

We’re excited to announce our new partnership with US Games, BSN Sports, and OPEN Phys Ed! As the leader in curriculum development, OPEN is creating brand-new stacking activities that will launch ahead of this year’s STACK UP! event. This partnership brings teachers even more resources to engage students through fun, inclusive, and standards-based activities—helping make STACK UP! bigger and better than ever.

You can find Speed Stacks gear on the US Games website and explore free OPEN resources at open.varsityuniversity.org.

Group Order

Turn Sport Stacking into a Fundraiser! With our Group Order Program, students can purchase their own Speed Stacks® sets right at school—making it fun and convenient for families. Even better, every order helps your program earn funds that go directly toward new PE equipment. It’s an easy way to engage students, excite families, and support your program at the same time!
