It is quite a ex exhibition, for $8, u get a pokeball, and u can use it interact with 4 machines to get clues on what Pokémon is hidden in it. There are 8 machines, some with clues like height or weight is just a waste of time.
The funny thing is, when u use your pokeball at the end to reveal the answer, you pokeball is actually reset and u can play with the various machines again, like clue on their voice, shadow etc.
So, if u really want to have fun, go in a group, solve the puzzle, but do not tell each other the answer. Once u reset the ball and gotten your answer, swop it with your friend and play it again.
LOL... cheapskate I know ...
The photo taking session with pikachu is at 430 pm if u are interested.
