What is the Cube Tower Challenge?
Instead of competing with single puzzles alone, you take on tower challenges which test your endurance. Each tower has a set of cubes that must be solved back-to-back and non- stop. Your speed and consistency across multiple cubes determine if you win a trophy or not.
This unique format created by Brain Studio tests:
- Multi puzzle mastery
- Transition speed between cubes
- Calmness under pressure
- Competitive creativity
It is fast, fun, and rewarding.
