Solitaire 2G Double is classic Klondike played with two decks: 104 cards, nine tableau columns and eight foundations. More cards mean more moves and fewer dead ends, so you can relax and enjoy every game instead of racking your brain. HOW TO PLAY • Build the tableau down in alternating colors and move whole runs at once. • Only a King can fill an empty column. • Move cards to the foundations by suit, from Ace up to King. • Tap the stock to draw three cards. • In Easy games all three drawn cards can be played; in Hard games only the top one. FEATURES • Unlimited undo and hints — tap the empty table for a quick hint • Auto-complete once every card on the table is face up • Separate statistics for Easy and Hard: games played, wins, best score, best time, fewest moves and winning streak • 9 Game Center leaderboards • 4 card face styles, 36 card backs and 4 backgrounds — or use your own photo • Left- or right-handed layout • Portrait and landscape on iPhone and iPad, optimized for iPhone Duo • Play in English, Simplified Chinese, Traditional Chinese, Japanese, Korean or German Free to play, supported by ads.

unBlackjack is a real blackjack game built for the phone in your hand. A proper six-deck shoe, a dealer who plays by the book, and nothing between you and the next hand. THE RIGHT PLAY, WHEN YOU ASK Unsure whether to hit, stand, double or split? Ask, and unBlackjack shows the mathematically correct move for your hand against the dealer's upcard. It never nags and never interrupts. Over time, basic strategy starts to feel natural. A TABLE WORTH COMING BACK TO • A real shoe, dealt and reshuffled the way a casino deals it • A dealer who follows the house rules every hand • House rules you can set to match the table you plan to play • Ivory cards on deep green felt, with a calm, quiet table • A clear result and a clear payout after every hand KNOW WHERE YOU STAND Your bankroll and session result sit at the top of the table. Test an approach for a hundred hands and see what it actually did. If the bankroll runs dry, a free top-up is always one tap away, with no ad attached. BUILT FOR IPHONE AND IPAD The table is laid out for both, in the same refined design. FREE TO PLAY Every hand and every feature is free, supported by ads. A single $6.99 purchase removes the ads for good. There is no subscription, nothing renews, and there is nothing to cancel. If you bought unBlackjack when it was a paid app, you are already ad-free and there is nothing to do.
