Rita quickly found something near the shelf that looked like a game joystick. When she pushed it left and right, the falling block moved accordingly.
Beside the joystick sat a small square button shaped like a book. Each press rotated the block ninety degrees clockwise.
A few other players who recognized the game were trying it too, while those who had never seen such a thing before stared at them intently, watching every move.
Rita opened the team channel and began explaining her theory to her teammates, outlining how the game probably worked.
It was still just a theory, so no one rushed to act.
When their falling blocks lined up perfectly and actually disappeared, the rules became obvious.
The design of the arena made sure that every team who figured it out first had their every move observed by all others.
The gameplay wasn't complicated. As soon as Rita and the other quick learners confirmed how it worked, the rest of the watching contestants understood too.
