Take turns drawing one line between two neighboring dots.
Set your names right in the scoreboard — tap a name to edit it. Names lock once the game begins.
Complete the fourth side of a box and it's stamped with your color and number — you immediately get another turn.
Your target to win is shown in the scoreboard: a bit more than a fair share of the boxes for the number of players.
First player to reach that target wins right away — the grid doesn't need to fill up.
If nobody reaches the target before every box is claimed, whoever has the most boxes wins.
Turn on "Pre-drawn lines" before starting a game to have the computer sketch in a few lines first.
Check "Player vs AI" for a 1-player game. The AI always takes a free box when one's available, avoids handing you one when it can, and picks its sacrifices carefully when it's forced to open a chain.
Tap the small icon next to a player's name in the scoreboard to pick a token — it'll show up on their boxes instead of a number. Tokens lock once the game begins, same as names.
