Whose Kitten?
Read full descriptionHide 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.

Verdict
The clearest difference is ads: Lucid Sudoku at none against Whose Kitten?'s shown. Whose Kitten?'s advantage is iOS requirement (14.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
