You can now share your score on Swap it with your friends !
Using brand new Google Play Game Services, Swap it now helps you brag about your success. For each level solved, you get 20 points if automatic solver was not used, and 10 points if you look at the solution at least once (no further penalty for peeking).
Once connected to g+, you will be able to access to your success list and to the leader board. Which of your friends will score the highest ?
