Who builds the fastest, smartest and most precisely?
This colorful set of 8 sturdy blocks and 60 challenging challenge cards transforms every game into a fun mix of speed, strategy, and focus. The challenge cards increase in difficulty, making the stacking game suitable for a wide range of developmental ages—from young builders to adult enthusiasts.

The classic rule is simple: ready... action... stack! And yes, the clock is ticking relentlessly. But this game offers much more than just frantic action. Thanks to its visual-motor approach, it trains spatial awareness, planning, fine motor skills, concentration, and teamwork. Perfect for the therapy room, classroom, or home.

Game variations:
- With or without time pressure
For quick thinkers and calm planners alike. Without a timer, the focus is on accuracy and motor control, while the time pressure emphasizes speed, overview, and reaction time.
- Communication & collaboration
With two identical sets: one player builds, the other player is unseen and receives only verbal cues. Ideal for practicing language use, listening skills, spatial concepts, and executive functions such as inhibition and working memory.

This stacking game lets players experience the joy of building together, exploring, and challenging themselves again and again. An energetic, educational, and surprisingly versatile game that keeps you hooked.
