as long as the grown ups don't mind getting beat by a kid!
here is the description from the makers of the game, FatBrain:
"Acuity is the clever matching game of quick
visual perception where players race against each other or work
together to discover and match hidden patterns in the tiles'
arrangement.
First, 70 wonderfully durable and vibrantly mind-bending pattern tiles,
are set in a grid arrangement of 36 tiles. Your job will be to find a
match.
Here's the kicker. None of the tiles match. Not one. All 70 are
different. Sooooo that means to find a match, players must find two
side-by-side tiles that together, by looking at 2 adjacent squares on
each - would match the tile that you're hoping to match. Or-
alternatively, players could find the matching pattern by looking at the
corners of 4 tiles together. *If you can't see a match, you can turn
one tile one quarter of a turn to make one. It's easy.
Easy until your mind's eye tricks you! It's the surprise in finding a
match or thinking you've found a match (when you really haven't) that
makes Acuity a one-of-a-kind, long-lasting source of fun game play over
time. Acuity is never, ever the same game twice. Really. Not ever.
Featuring 70 wonderfully durable and vibrantly mind-bending pattern
tiles, Acuity will delight all ages. With simple rules, Acuity is a
game the entire family can play together. No reading required... simply
the ability to flip, turn and match!"
