4 in a row

Four in a Row against the watch, ported from wasp-os's four_in_a_row. You play red and the watch plays yellow.

Using it

• The menu has three cards. Tap a level button, 0 to 3, to choose how hard the watch plays. Each level makes it look one move further ahead; at every level it takes a win and blocks a threat.
• The bottom card shows the share of games you have won at the chosen level. Levels and results are kept for next time.
• Swipe down on the menu, or tap the top card, to start a game. You and the watch take turns to go first, game by game at each level.
• In a game, tap above or on a column to move your red counter over it, then swipe down to drop it. The watch answers with yellow; while it works out its move the top shows Thinking.... Its first counter or two go in a random column.
• A full column, or a swipe while the watch is thinking, gives a short buzz and drops nothing.
• Four in a line across, up or diagonally wins. The top then says You win! with a short buzz, You lose! with a longer one, or Draw once the board is full. Swipe down to go back to the menu.
• Swiping right on the menu, or left, right or up in a game, goes back.
