Your new sickness : SingleOut.
At home, at work, on the bus, on an airplane, between two emails, when on break, in the toilet, in a commercial break, when and where ever is boring...
long story short, SingleOut will be an addiction for you!
Find the different coloured box from within the lying three, and send it to the empty space! Your excitement will increase while the time to play a hand decreases.
Since it does not require internet connection, you can play it anywhere.
Lets see your top score!
