Take a deep breath. Theme Worlds is the relaxing word game made for quiet moments. No timers, no lives, no pressure, ever. Swipe a wheel of letters to fill themed crosswords, and watch every word you spell bring a painterly world to life. Most word puzzles fill their grids with random words. Ours do not. In Theme Worlds the words belong to the place you are in: TIDE, PEARL and REEF beneath the Coral Reef, EMBER, MAPLE and HARVEST in Golden Autumn, LANTERN and STREET in London Mist. It feels like solving a tiny story instead of a grid. A CALM ESCAPE, BY DESIGN • Zen pacing: no clocks, no energy meters, no game over. Solve at your own speed. • More than 3,500 themed levels: 100 in every one of 28 worlds, plus 30 in each of 28 Day Trip towns. • Painterly scenery under a serene glass interface. Skies drift from dawn to dusk as you advance. • Music written for each world, so New Orleans sounds like New Orleans and Tokyo sounds like Tokyo. • Plays offline. No wifi needed on flights, commutes or quiet evenings. ELEVEN FREE WORLDS Sunrise Meadow, Redwood Fog, Coral Reef, Golden Autumn, Aurora Winter, Desert Canyon, Lavender Fields, Monsoon Jungle, Stormlight Coast, Observatory Peak and Midnight Library. Eleven hundred levels plus the daily puzzle, free forever. SIXTEEN PREMIUM WORLDS TO COLLECT Travel farther with one time unlocks you own forever. Across America: California Coast, Florida Keys, New York Nights, Lake of the Ozarks, Chicago Winds, Vegas Lights, New Orleans Jazz, San Francisco Fog and Nashville Strings. Around the world: Neon Tokyo, Paris Lights, Kyoto Lanterns, London Mist, Rome Eternal, Sydney Harbour and Rio Carnival. And the deluxe Hawaii Island, a three act journey from dawn to torch lit night. Every premium world has bigger grids, its own music, and a friends leaderboard. TRAVELER CARDS Premium worlds award a Traveler Card every fifth level, twenty per world, and each Day Trip town adds six more. Finish a level flawlessly and the card turns gold. Complete a set for 1,000 coins, a gold set for 2,500, and a grand prize celebration. DAY TRIPS Every world has a small town beside it, and you earn your way in. Finish thirty scenes in a world and its ticket is yours, then the town opens for a small one time price: thirty more scenes and six Traveler Cards. Giverny from Paris, Rye from London, Kamakura from Tokyo, and twenty five more. WEEKEND GAMES Three small games open every weekend. Climb a word ladder, trace six hidden words in a grid, or turn over postcards to find every pair. Clear one for coins, clear all three for a bundle and a spare Day Trip ticket. FIND THE HIDDEN KEYSTONE A keystone word hides in the artwork of every level. Spot it for bonus coins. REWARDS EVERY DAY • A fresh daily puzzle with streaks, and Rest Days so one missed morning does not undo your progress. • Milestone chests and a bonus for finishing every world keep the coins coming. • Bonus words earn coins, so a big vocabulary is always rewarded. • Journey Album: a postcard for every world you complete. PLAY WITH FRIENDS • Invite friends with your six character code, and you both start with a bonus. • Game Center leaderboards for streaks, scenes and keystones. • A spoiler free share card for the daily puzzle. EARN YOUR WAY IN, OR PAY Nothing is locked behind money alone. Every world and every Day Trip town opens with coins you earn by playing, or with a purchase if you would rather not wait. Finishing a world earns roughly enough to open another. WHAT A PREMIUM WORLD GIVES YOU A third act: the scene carries on into night as you play, where free worlds close at dusk. Twenty Traveler Cards instead of five. Its own signature tile material. The ticket to its Day Trip town, included. A friends leaderboard, and a panorama when the set is complete. We would love to hear what you want next. Write to David@app-developments.com with ideas for new worlds. Pour a cup of tea. Pick a world. Unwind, one word at a time.

About

Whose Kitten?

Features
Read full description

A kitten is left at your shelter door. No name tag, no note. The only clue is the face — a folded ear, one blue eye, a paw with an extra toe. Read the parents in the kitten's face, then search the town to find them. ▪ A face never lies Coat color, pattern, eyes, ears, tail, toes — every cat in this town is born by real genetic rules. Why two black parents can have a calico, why odd eyes show up in only one of the litter: it is all in the game. One recessive trait in the kitten is proof that a parent is hiding it. ▪ Search the town Parking lot, market, park, playground, alley, riverside, abandoned factory. Each place has its own cats, and day and night bring out different ones. Sneak up and scoop a cat into your arms, lure one with food, or set a trap and come back later. Shy cats play hide and seek — catch their eyes and look under things to find them. ▪ Decide only when you are sure Observe the candidates you brought home, confirm their traits one by one, and name the father and the mother separately on the elimination board. Guessing will not get you through. ▪ Run the shelter Food and water, litter boxes, the right toy for each cat, wand play, brushing and lasers. Place the furniture wherever you like. As trust grows, cats greet you first, bring you gifts and show their own little habits. Well-cared-for cats are adopted by good families, and letters arrive later. Take photos for the album and fill your family book and family tree. ▪ What this game does not do · No gacha. Cats are met, not rolled. · Cats in your shelter never die. · No pop-up interstitial ads. Rewarded ads play only when you tap the button. · Nothing is sold to undo a failed case. ▪ Good to know · Sign in (Apple or Google) to keep your progress and purchases on your account across devices. Without signing in, everything stays on this device. · Portrait, one-handed play. A full loop takes 5-10 minutes. · Korean, English, Japanese, Chinese (Simplified/Traditional) and Spanish.
