Category Stack is a relaxing word puzzle that plays like solitaire. Every card belongs somewhere: find its category, stack it in the columns, and send whole piles home. HOW TO PLAY • Drag a category card to an empty pile to open it, then drop its words on top. • Stack cards of the same category in the columns, with the category card at the bottom, and move the whole stack home in one go. • Draw from the deck or park a card in the tray when you need room. • Clear every category before you run out of moves. WHY YOU'LL LOVE IT • 1000+ categories and thousands of cards: animals, food, music, space, and clever word play like "Fire ___" and "Things You Break". • Every card has its own picture, so even tricky words are easy to spot. • Combo streaks: put cards home in a row to earn extra moves and coins. • Golden cards: send them home before they fade for bonus coins. • Helpful boosters: Hint, Undo, Joker, Magnet and Hammer. • Daily Punch Card: claim a reward every day, with a big prize on day 7 and treasure chests along the way. • No rush, no timer: think it through and play at your own pace. • Play offline, anytime. • Made for iPhone and iPad. Perfect for fans of word games, solitaire, associations and brain teasers. Sharpen your mind one category at a time!
