Grid-cells are numbered naturally, from top-left to bottom right and

• Player-1 and player-2 click cells/numbers alternately
• cells clicked by player-1 are indicated by a gray top-half fill
• cells clicked by player-2 are indicated by a green bottom-half fill

Player-2 is to keep his choices evenly distributed relative to those of player 1.

This is measured by the score at each cell n: the number of clicks in [1,n] that any player has achieved since the last click in [1,n] by the other player.

Rules

• Player-2 needs to keep the score of each cell below 5
• No player can pick any number he has previously picked
• Player-2 cannot click a number which is adjacent to one he has previously clicked.
• Player-2 may pass his turn by clicking outside the grid.

Player 1 wins when player 2 violates one of the restrictions above

Player 2 wins if he has not lost by the time player-1 has picked all cells.

Press Auto1 to play as player-2 against a random-picking player-1.
