Seven AI opponents rebuilt
- Hearts - scores now carry over between hands and the game ends properly when someone reaches 100. Hard now tracks played cards and voids, and takes less than half the penalty points Medium does.
- Spades - spades can no longer be led until broken, the opening lead rotates, and Hard counts tricks when bidding and avoids overtaking its partner. A Hard team beat a Medium team in about nine games out of ten in testing.
- Gin Rummy - you can now knock. Runs of five or more cards count as melds, layoffs and the gin and undercut bonuses are scored, and the hand is a draw when the stock runs down.
- Cribbage - full hands now play through: pegging with runs and go, then the show with the non-dealer's hand, the dealer's hand and the crib counted on screen, alternating deals and pegging out at 121.
- Pente - the AI now always takes a win before blocking, defends against capture threats, and Hard searches several moves ahead.
- Go - the AI passes when nothing useful is left instead of filling its own territory, ko follows the standard rule, and dead stones are removed automatically at the end.
- Chinese Checkers - a proper star-shaped board, and an AI that fills its home triangle all the way to the back row.
Puzzle fixes
- Kakuro - new puzzle generator that follows the real no-repeat rule, an on-screen number pad for phones and tablets, and arrow keys that skip clue cells.
- Mahjong Solitaire - every deal can now be cleared, the Large layout is genuinely larger (122 tiles), the Bamboo suit has been added, and scores are ranked by time.
- Nonogram - any grid that satisfies all the clues is now accepted as solved.
- Typing Speed - playable on phones (tap the board to bring up the keyboard), typing locks onto the lowest word, and switching tabs no longer costs lives.
Other fixes
- Four in a Row and Sea Battle load correctly again.
- Taps on phones now land on the right column in Four in a Row and the right pit in Mancala.
- The Forfeit button works again in multiplayer games, and timed multiplayer games end when the clock runs out.
- Account data is better protected: email addresses are no longer visible to other players.
- The homepage activity feed shows the difficulty each game was played on.
