This is a Christmas-themed game.
Look on the left for your target image. Now find it on the right and tap it before it disappears.
There's a variety of different games and 100 levels of 3 minutes each.
There are 3 levels of difficulty - choose a reindeer, elf or Santa (if you're brave!)
If you make no wrong taps then you get a Gold tree at the end of the level.
