How to Play
The object of Loopy is to form a loop with your chips.
The rules are simple:
Players alternate turns placing chips on the game board. Red moves first.
As in Tic-tac-toe, once a chip is placed, it cannot be moved.
To counter the advantage of going first, the second move by red cannot be

connections must fully enclose at least one square on the game board,
regardless of whether or not that that square is occupied by a chip of
