Tonight is Yuri's Night, the night that space exploration enthusiasts around the world celebrate Yuri Gagarin's first manned spaceflight on April 12, 1961 and the first space shuttle launch on the same date in 1981. If you are staying home with family and want to commemorate this event, you should check out the Space Race Card Match app from Kids Discover.
Space Race Card Match is a memory / matching game with an astronomy theme. The app is challenging as you have to successfully match every card on the board in a short period of time. If you make too many mistakes or take too long, you are forced to repeat the level. If you win the round, you are rewarded with beautiful images, diagrams and facts about the sun. The app ships with a free sun-themed level, and you can buy either a space exploration theme or a life in space theme. Both of these latter themes are available as US$0.99 in-app purchases.
