Mahjong Keep is a calm mahjong solitaire with a story. Every board you clear earns a star, and stars rebuild a ruined castle on a floating island, and the lives of the people who call it home. MATCH, RELAX, REBUILD Match pairs of free tiles to clear the board. There are no timers. Every board is dealt so it can be solved, but a careless match can leave you stuck, and that's when Undo, Hint, Shuffle and the Magnet come in. CROWNS AND STREAKS Quick matches in a row build a combo and a bigger score, and every board gives up to three crowns. Fill a chapter with crowns to open its chests, keep a winning streak alive for bonus coins, and come back each day for the daily streak. A CASTLE TO BRING BACK Ten chapters and 160 boards in the shapes of a teapot, a loaf, a crescent moon and more, from the gatehouse to the ramparts. Mend the well, plant the gardens, hang the great bell, and choose how each piece looks. Martha, Bertram, Nell and Tomas, and the rest of Briarwood tell their story as the castle comes back to life, and Pepper the little dragon and Barley the horse move in along the way. EASY ON THE EYES - Big, clear tiles with three face styles: Easy Read (with numbers in the corner), Classic, and Home and Garden pictures. - Free tiles are brightened and blocked ones dimmed, if you like. - Stories can be read aloud. - Works with larger text sizes, VoiceOver, and Reduce Motion, on iPhone and iPad. A NEW BOARD EVERY DAY The Daily Challenge is the same board for everyone each day. Play any day this month you missed, and fill a month to earn a golden trophy for the castle. Free to play, all ten chapters, with free undos, hints, shuffles and a magnet every day. Careless matches can trap a board, so choose your pairs with care: a shuffle or an undo gets you out, or start the board over. From chapter 3 the game shows an occasional ad between boards, never while you play; Remove Ads (one purchase) turns them off for good and gives every reward without a video. Make the castle your own with tile and castle themes and more than twenty decorations, from beehives to a windmill on its own little isle. The Castle Club includes Remove Ads, unlimited help, every theme, and a new decoration each month. Castle Club is an auto-renewing yearly subscription. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before the end of the period. Manage or cancel it in your Apple Account settings, or in the game's Settings.
