Solitaire is a trusted timewaster for lonely people. Solitaire+ proves that the classic solo card game can be even more fun when played against someone else.
The idea is that you play a three-round, knockout tournament in real time against a random opponent. Both players begin with the same shuffle, with points awarded every time a card is sent to the "foundation".
It's a fun, manic race to clear the deck first, although the wait times between tournaments are excessive.
