Quick answer
Choose Roly Poly if you want a playful, rounded character that tends to wobble and roll, making it a good first character build. Choose Strumpy if you prefer a sturdier, more upright figure that stands its ground during play. Both are Circuit Cubes STEM toys with online build instructions, so your decision mostly comes down to which personality fits your builder.
What each character build includes
Both Roly Poly and Strumpy come with all parts pictured in their product listings. That means you get the pieces needed to complete the character as shown, without hunting for extra bricks. Build instructions are available online rather than printed, which keeps the toy price lower and reduces paper waste. If you have questions about the parts or the build, you can email the store directly.
The main difference is in the character design. Roly Poly is a rounded, roly-poly style figure that likely rolls or wobbles, while Strumpy has a more grounded, stompy stance. These are character builds, not motorized robots, so the play pattern is about constructing and posing rather than driving or programming.
Price and value comparison
At catalog prices, Roly Poly is listed at USD 13.79 (compared to a regular price of USD 19.99), and Strumpy is listed at USD 12.39 (compared to USD 19.99). Both are discounted from the same comparison price, so the savings are similar. Strumpy costs slightly less, but the difference is small enough that you should choose based on the character your child prefers, not just the price.
Because both sets include all pictured parts and use online instructions, you are paying for the same core experience: a complete character build with no printed manual. If you want the most affordable option, Strumpy has a slight edge, but both are priced as budget-friendly STEM toys.
Build difficulty and play pattern
Neither product listing specifies a recommended age or exact part count, so we cannot claim one is easier or harder based on official data. However, the character shapes suggest different building experiences. Roly Poly's rounded form may involve curved or angled pieces that create a rolling motion, which can be fun for younger builders who like movement. Strumpy's upright design likely uses a more traditional stacked structure, which may appeal to builders who want a figure that stands on its own.
Both are open-ended enough to combine with other Circuit Cubes parts, but they are sold as standalone character builds. If you already own other Circuit Cubes kits, these characters can add variety to your collection.
How to choose between them
If your builder enjoys toys that wobble, roll, or have a silly personality, Roly Poly is the better fit. If they prefer a character that stands tall and looks sturdy, Strumpy is the stronger choice. Since both include all pictured parts and online instructions, the decision is mostly about which character design will get more playtime in your home.
Keep in mind that neither set includes a Bluetooth controller or motors like the Tracker kit does. These are purely character builds. If you want motorized movement, you would need a different Circuit Cubes product. For a simple, affordable character build, either Roly Poly or Strumpy works well.
