"LoterĂa is a traditional Mexican game, similar to bingo, but using images on a deck of cards instead of balls with numbers. LoterĂa Go is a super-sized version of this that gets you outside and walking to neighborhood parks.
Can you find the LoterĂa cards we've hidden in the streets?"
They don't speak spanish either, there are so many mistakes on that flyer
Somehow that doesn't surprise me!
